LG optimus l7 ii dual p715 red. LG Optimus L7 II - Technical characteristics. Communication between devices in mobile networks uses additional technology that provides different data transfer speeds

LG has become one of the first Android smartphone manufacturers to join the race to capture its share of the pie in the dual-device segment. The first attempts were unsuccessful, until the release of phones with support for two SIM cards, having obtained your right. At that time (end of 2011), the interface and ease of operation with two cards were the best among analogues, of which there were not so many. From the very beginning, LG began to adhere to one principle - to create two identical devices (the only difference is that there is an additional key for working with a SIM) - one is primary, the other is the same in design, functionality and capabilities, for the sake of support of another SIM, obviously The interface needs to work with them. Today we welcome the senior model of the updated line of stylish L-Style smartphones – LG Optimus L7 II Dual. As you might have guessed, this smartphone uses two SIM cards and is a successor to the popular LG Optimus L7 model.

Design and ergonomics

Exterior look LG Optimus L7 II Dual is its calling card. The smartphone looks compact, with a thin frame around the screen, not just on the sides, but above and below it. Rounded edges enhance this effect even more. It is true that this is a visual deception. The renovation showed that the dimensions between the devices are uniform despite the even greater height of the earlier models.

In numbers it looks like this:

LG Optimus L7 II Dual – 122.2 x 66.6 x 9.7 mm, 115 g
LG Optimus L7 II – 121.5 x 66.6 x 9.7 mm
LG Optimus L7 – 125.5 x 67 x 8.7 mm

And so in the photographs

Equal dimensions compared to other DualSIM smartphones with a 4.3-inch display

Model/Parameters	Dimensions, mm	Vaga, Mr.
LG Optimus L7 II Dual	122 x 67 x 9.7	115
	130 x 68 x 10.7	131
	129 x 66 x 9.9	145
	128 x 68 x 10	136

Whatever the case, the dimensions do not interfere with the attractive appearance of the LG Optimus L7 II Dual, so you will be amazed at its front. Varto look at this side, as if the enemy is viparous. Kumedno, but also with one type of alloy, L7 and L7 II are designated as devices of two different price segments. The first model looks more expensive and stylish due to the design of the later lines with a pussy-shaped top that harmonizes with the straight lines of the body. The Optimus L7 II does not have this. The sides of the body are rounded, and the edge on the corner, which is removed, has the appearance of a honeycomb, which in no way adds any appeal to the design. In both this and the other model, the back panel is slimy.

The difference of 1 mm of thickness allowed the Optimus L7 II Dual to accommodate a battery with a capacity of 2460 mA/year, which is approximately 45% larger than the front! Perhaps, not without reason, Ken Hong (director of communications at LG Electronics) in one interview stated that there is no difference between a phone with a thickness of 8 and 9 millimeters, which is confirmed in practice, in the application L7 and L7 II, y What difference does it make between people and the millimeter?

The vertical display of the same diagonal, with an additional 4 mm height in the Optimus L7 II, was inserted behind the frame of the view from the silver insert of the operating side of the body, which is present in the Optimus L7. If this frame is not fixed, the height of smartphones will increase to a millimeter, so there is no magic here.

On the front side of the LG Optimus L7 II Dual there was a VGA camera lens left-handed in front of the speaker grid and a proximity sensor right-handed in front of it. Between the screen and the display there is the printer's logo. Under the display, from the left to the right, there are several touch keys – “Back”, “Home”, “Menu” and “Change SIM priority”. Our copy does not have backlit keys, so you may have to use them manually. Rotating the keys and changing the priority of SIM cards under the display is not the best idea. Within an hour of using the smartphone, there were outages that, without even noticing, changed the priority of operators, thereby making calls and sending text messages from the “wrong” SIM. Since the doctor simply gave the device the addition of a hardware key “Swipe button”, we don’t understand why the same change would not be transferred to the SIM priority. This would have eliminated the hassle of hassle and allowed the placement of the interface control keys in a more thoughtful manner. I would like the LG Optimus L7 to have the same thing, with one mechanical button in the center and two touch keys on the sides next to it.

As in the LG Optimus L7, the front part of the body is covered with plastic. Doctors, as well as the presence of an oleophobic coating, will often have to wipe off their sore fingers, and it’s not easy to use a special fabric on the microfiber fabric. The maximum brightness of the backlight of the display can only cope with daytime lighting, but at times, it’s scary to realize what it will be like on a bright, sleepy day.

The sides of the body are framed with plastic, which protrudes above the front panel to match the color of the body. The center of the body, as seen from the side, is separated by a silver insert “metal-like”. It has all the mechanical keys and connectors like a smartphone. On the left side there is a specially programmed “Shvidka key” at the top end and a key that is slightly lower. On the right side there is a life-blocking key. The sound and life keys are located on the same level above the body, so the key that can be programmed does not protrude above its surface. It is not easy to know it blindly, but there are no similar problems with two others. All buttons have a short and clear motion.

At the top end there are two openings, one for connecting headphones, and the other for noise reduction when talking. There are two openings at the bottom end. The central one has a Micro-USB interface connector for connecting a charger or data cable, and the right-handed one is the main microphone, which is also used for recording and recording sound with a voice recorder.

The back side of the body is rounded. As we have already written, its main part is visible in the form of honeycombs. There is a new 8 MP camera lens, an LED light, a logo and two slits under the speaker with a small protrusion between them, which helps to muffle the sound when the phone is lying on the table. There is no edge cutout for removing the rear panel. This device has a hole on the bottom (Micro-USB). Under it there is a battery with a capacity of 2460 mA/year, a slot for memory cards and two slots for SIM cards. The design allows you to change the memory card without removing the battery. Its dimensions can be compared to those that fit into the Optimus L7, being less than a trifle thin. Uninstallation of SIM cards will affect the battery.

The selection quality of the LG Optimus L7 II Dual is difficult to evaluate. Our early test sample does not have any fault with the gaps between the parts, so it “belongs” to someone else. Based on the LG Optimus L7, you can assume that commercial devices have problems with creaking and play.

Operating system and shell

There is no reason for doctors to be surprised by the fact that the smartphone runs on the Android operating system version 4.1.2. On top of the Google shell is the proprietary interface Optimus UI 3.0. For some reason, this interface could be avoided in . I'm worried about responsibilities.
First you start from the lock screen. Every day, select the screen unlock mode. And only those that are in , are primary and no longer as advantageous as those available in LG Optimus G. Primary include: “Swipe”, “Unlock by face”, “Pattern”, PIN and “Password” ", or completely without blocking.

The work table can be switched on from one to seven windows. The row of shortcuts at the bottom of the screen holds one to six shortcuts. The shell supports the creation of folders by dragging labels one on one. The notification panel displays a row of switches (11 pieces) that need to be adjusted, a brightness control knob, a date, an hour and a button to go to the “Adjustment” menu. Through a small part of the screen, the row with QSlide programs is visible.

When customizing the desktop, you can select the type of effect when switching between windows, one of four themes, set cyclic scrolling, and also activate the ability to work with the interface in landscape mode. Another feature that was not present in the LG Optimus G is the choice of the size of the icons, they can be either standard, which occupy one middle, or large, which occupy several parts. Perhaps the developers wanted to develop the interface for more handy people with a dirty eye, but it would be impossible to place such a label in the bottom row of a smooth launch. As a result, in addition to waste, there is no crust at all.

The digital keyboard for dialing a number emphasizes the Latin alphabet. The list of programs can be represented either in a 4x5 or 5x6 matrix. For your convenience, you can select song shortcuts, select a background image and sort programs by alphabet or date of purchase. Along with the shortcuts you can see the programs and widgets you are interested in.

Safety Care appeared in the middle of the program. It allows you to add your coordinates to text notifications on the task number in the box when you dial the emergency number. Make sure you know the coordinates if your phone is inactive for a period of time (from 12 years to 3 days, or manually perform tasks), including before the battery runs out or when you dial one of the saved numbers from afar from the phone book. This program can be useful in emergency situations, troubles, so that at this moment you do not lose money and/or pennies for storage. I wish all smart phones had something like this. It is possible that the reality of life lies.

Text messages have lost the ability to select a window with conversations and dynamic scaling, without changing the background image. The gallery, as before, supports a “pinch” gesture to change the amount of content that is displayed, and the video player no longer has such a function.

SIM settings allow you to select cards from the first and other slots, assign one of the five icons to them, set a color scheme, turn on data transfer by selecting one of the two SIM cards and allow them not to be cut off when found in roaming The type in the “Mobile Measurements” section can be changed to determine which cards will be used in 2G and 3G modes. In the “Data transfer”, “Call settings”, “Sound” and “About phone” menus, you can make fine adjustments, including the ringer melody and forwarding, or view the report information about the SIM card.

The set of QSlide add-ons consists of one video programmer. As in the LG Optimus G, you can adjust the display level of the imager, move it around the screen, or pause or scale it. However, when using Optimus G, the smartphone interface supports horizontal orientation, and you can also watch videos in landscape mode. It’s impossible to launch a browser, calendar, calculator or notes, which is surprising, and even for one-hour work, these programs clearly require fewer resources than when watching a video in a local window. The nice thing about it was the ability to read and respond to information without going all the way to the supplement. The login notification is displayed in the pop-up window at the top left corner of the screen. To inform someone, you need to click on the empty row under the text until the QWERTY keyboard appears.

Hardware platform

The smartphone has a Qualcomm Snapdragon S4 Play MSM8225 chip system installed. The same vikorist in i. It is manufactured using a 45-nm process technology and includes two Cortex-A5 processor cores with a maximum clock frequency of 1 GHz, an Adreno 203 graphics core and 768 MB of RAM, for which the system has a storage capacity of approximately 620 MB. Due to the fact that it is turned on, before any program is running, you can lose a maximum of 295 MB. This, as well as the modest graphics capabilities of the processor, make it difficult to use the LG Optimus L7 II Dual as a device for running current 3D games. Let's talk about the weak performance results of tests of the smartphone's graphics capabilities. Well, if you don’t want to be incredibly powerful, forget about the power of the LG Optimus L7 II Dual, as well as the fact that the LG Optimus L7 has 512 MB of RAM, with only 390 MB available on any system, and even less for add-ons, close to 135 MB, everything is wrong and bad with the new product. Moreover, as we have already said, the same hardware platform runs HTC Desire X and the twin HTC Desire SV. The productivity results remain almost identical to those shown by the LG smartphone.

The strength of the received signal does not respond to problems with connections between the places. The loudness of the loudspeaker is sufficient for loudness in a quiet area, but without reserve for loudness in noisy places. The noise of the other speaker is average, the vibration and click of the ice is excellent.

The speed of GPS satellites and the strength of the received Wi-Fi signal are typical for modern devices without obvious weaknesses and strengths.

The strength of the LG Optimus L7 II Dual is the hour of work. The Antutu test showed 769 points or 4 years and 17 hours. With this result, you can safely pay for two jobs with a small number of calls, use Wi-Fi and 3G for reading news from social networks and browsing, 10-15 days of work with GPS, and listening to music every year. and for a day. In the mode of watching HD video from Youtube via Wi-Fi at 70% brightness, the LG Optimus L7 II Dual takes 6 years and 30 hours. At 50% brightness – 8 years 45 hours. At 0% brightness (comfortable for viewing in the dark) 11 years and 50 hours. An hour of work in player mode (MP3, bitrate 192-320 kb/s, volume is 12 out of 15 possible levels) becomes a little more than 23 years. In the reading mode (FBReader), you can purchase 8 years and 45 readings at 50% brightness or 15 years and 41 readings at 0% brightness.

Display and camera

The model is equipped with a 4.3-inch True IPS display with a separate section of 800x480 pixels, pixel density 217 ppi. The image brightness is adjusted to the LG Optimus L7. As we were told at LG, such hostility developed through test images, but commercial images have no problems. The main complaint comes down to the obviousness of the erysipelas on the white aphid, as well as the low cuticles that are not powerful to IPS matrices. I would like to believe that this display is, in its features, more similar to a TN matrix, lower than IPS.

Another advantage is the absence of a light sensor, through which the brightness of the backlight must be adjusted manually. It was hoped that 250-dollar smartphones would be equipped with such a sensor, not to mention the ones that would require you to pay $330. Brightness indicators range from 5.9 cd/m2 to 284 cd/m2. Half brightness shows a value of 66 cd/m².

100% display brightness on the first two photos and 50% on the remaining two photos

As is the case, for HTC Desire V and HTC Desire SV, LG upgraded the main camera, replacing the 5 MP module with an 8 MP one. However, unlike the HTC twins, the L7 is equipped with a front VGA camera.

Regardless of the fact that in the L7 II Dual the matrix with back-up irradiation (BSI) is used, the number of images lost at about the same level. The interface has become even more different. Added the ability to follow a voice command and the ability to edit and expand labels. The video mode has been adjusted for brightness. The maximum video size is 740x480 pixels. To make things more polished, HTC Desire SV can boast of a large 800 x 480 pixel resolution.

Pouches

The new generation of L-Style is even better in front. The LG Optimus L7 II Dual smartphone has a compact body, with which the capacity of the installed battery has almost doubled. The hardware platform has been upgraded, now the current Qualcomm Snapdragon S4 Play with a 1 GHz dual-core processor and 768 MB of RAM. The separation of the camera has increased, although this has not greatly affected the storage capacity of pictures and videos. They finalized the interface, which is practically in no way compromised by the top-end LG Optimus G. Overall, the smartphone is deprived of attention, and given the fact that its price at the start is lower than that of the LG Optimus L7, one can assume that it is also popular for LG Optimus L7 II Dual will be significant.
The Optimus L7 II Dual has fewer competitors. The main one is that it will be on the same hardware platform, with a display of the same diagonal and a separate camera. On the HTC side there are clearer materials and folding. The LG laptop has an hour of operation, dimensions, the current version of the operating system and functional shell, as well as the presence of an additional key that can be programmed, and the ease of setting up SIM cards. Among the other strong competitors of the product are the popular i, as well as models with a 4.5-inch screen. All of them have a common low price, which can be compared with the Fly IQ446 Magic, and the functionality of the smartphone significantly exceeds LG and various other devices on the basis of the unique rotation of the life button or two speakers Acer has the same flexibility and productivity as Prestigio and Fly. The vibrator is foldable and stowable depending on your strengths and the breadth of your target, as well as the most compact device in this class.

Another generation of L-Style, now supported by two SIM cards

In the spring of this year, TV channels were broadcast with a strong advertisement of LG and Euromerges of smartphones of another generation of the “stylish” L-Style series. For the first time, the famous actor Kostyantin Khabensky, having acquired the European sales force, bought himself an LG Optimus L7 II Dual phone and said that “the battery is weak, that’s important.” Later on the screen appeared an advertisement for the same LG Optimus L7 II, but without the support of two SIM cards. And what’s surprising: these two seemingly contradictory models (nowhere else) turned out to be completely different from each other. Moreover, the significance here lies not only in the internal reality (which would be logical): there is no real similarity between the two models.

Since the single-camera model can rightfully be called a representative and spastic agent of the same L-Style, almost all LG smartphones in the middle and low price categories are new, so the current appearance of the product is new, described today, - LG Optimus L7 II Dual - correspondent It is not possible to find any characteristics similar to L-Style. That same “style”, featuring a typical urban design with a touch of industrial roughness, is what the single-family LG Optimus L7 of another generation still fully resembles. The two-dimensional version of the new “seed” looks completely different: a completely streamlined body from all sides, no sharp cuts, sharp transitions and straight chopped rice - everything is smooth and round. The headband itself is “metal-like”, running along the entire perimeter of the body, not flat, but also domed-rounded, folding together with other parts, which are smoothly rounded on the edges. Another notable note: the LG Optimus L7 II Dual does not have a mechanical hardware key in the middle under the screen, like some representatives of the L-homeland, then there are about three other touch buttons, another one, confirms for the militia change of SIM cards .

External appearance and handiness of the vikoristan

So, what is the LG Optimus L7 II Dual? It’s worth it to have a smartphone that’s small by today’s standards, with a body that has a candy bar form factor made of parts that have no place in metal. Everything here is made of plastic: the frame, the back cover, which can be removed to access the insides of the smartphone, and the description of the rim around the perimeter, which mimics metal. However, the dryness that covers the rare-crystalline screen is more mineral here. entirely clear, but with weak oleophobic coatings.

Due to the small dimensions and materials that are used in manufacturing, the smartphone is very lightweight, and due to the size of the selected shapes and small size, it miraculously falls into the average valley and sits comfortably there.

There are practically no sticky or soiled parts here: the back cover, like a back cover, and becoming most of the body, is made of matte plastic with textures applied to the outer surface. The main part of the lid looks like this, the bottom parts of it have been covered with a thick sandpaper, and the side parts are decorated with a grainy texture of a fluffy texture. Before speaking, at this point it is important to note that, depending on the color of the body, the texture of the outer coating of the back cover is different: in the white version, the entire purple surface of the cover, and not just the side edges.

And the axis is dry on the surface of the screen here, and, perhaps, is not protected by oleophobic coatings, so the display is already scratched with fingertips and it is important to wipe them off. Despite the fact that other parameters are completely neglected, the body “sags” compared to most of the smartphones we have tested before: the screen of the LG Optimus L7 II Dual is extremely dirty, and from this you won’t need anything. You can, however, stick some dry spittle here, but not without the Rozmov okrema.

It is true that due to the quality of the materials of the body itself, we soon began to have complaints about them. Over the course of several months, the soft plastic of the back cover of the device has become covered with a large number of large and small smudges, scuffs and tiny abrasions, so that lovers of pristine beauty can enjoy even more from the early days of the beautiful design. Sty this smartphone in a dry case and transfer the device to a new one.

The cover is securely attached and can be easily removed, for which it is enough to apply a fingernail to the same place as the Micro-USB connector. Beneath it, a completely familiar picture emerges: the damaged SIM cards, separated one from the other, are supported by the rechargeable battery when installed, so there is no way to talk about “hot swapping”. And the slot for the memory card is completely accessible at any time, just by removing the outer cover.

Before speaking, SIM cards here use the “old” Mini-SIM format, so some people who have switched to Micro-SIM (or Nano-SIM) may need an adapter. And in especially important situations there are two, because the LG Optimus L7 II Dual smartphone, as already mentioned, supports operation with two SIM cards. The battery here is also significant and has a great capacity for such a small thing (2460 mAh), so the smartphone will delight you with its survivability within reasonable operating modes. We'll talk about that later, but for now let's take a closer look.

There are more ceramic elements on the body of the LG Optimus L7 II Dual, but they are lower. First of all, at the bottom of the front panel under the screen there are not three, but several buttons, one of which, additionally, allows you to quickly change the priority SIM card. The icons of these buttons are painted with silver paint and do not light up. The big downside is that in your mind you have to press the buttons over and over again until you remember how to change them. Absolutely senseless and logical and unreasonable decision.

In another way, and this is already a welcome novelty, on the left side of the device there is one additional mechanical key, which can be assigned to the function itself. To select the robot mode, use the Quick button in system setups to select the next menu item.

Other keys are rotated: the tension adjustment wheel is on the left side, the live and lock button is on the right. The keys, it seems, are “correct”: they smell great, and stick out from the body long enough for them to be easily smeared. The move is soft, pressure-laden, there are no complaints at all, especially since the lock button of the LG Optimus L7 II Dual is moved not to the side, but to the side, which is handy, both for a right-handed person and for a shuffle.

As for the decision of elements, the audio output for headphones and headset (3.5 mm) is traditionally located at the top end of the device, and the universal Micro-USB connector is at the bottom, next to the opening of the main microphone. Another, additional microphone can be found at the top end, next to the audio output.

The LG Optimus L7 II Dual has two cameras, as every smartphone you love today, and one of them is flexible - there is a single LED light on the back surface. The camera window does not interfere with the frame that protrudes, and does not protrude beyond the surface of the body, so it can easily get dirty, which makes it easier. The speaker contains one curved rod, which serves to ensure that the cover of the smartphone rises in this place above the surface of the table. In this way, nothing interferes with the sound output from the speaker.

And finally, I would like to earn the respect of readers in this section of the article: although the LG Optimus L7 II Dual smartphone looks good and attractive in any of the color options - black or white - it is more practical to them, the unmarked and long-lasting ones here, definitely Try the best option. It is not anyone's fault that most of the descriptions of smudges and abrasions on the wrist, as well as fat and padded fingers, mean that the commercial appearance of the device in a white viconan can be preserved much longer.

Screen

The LG Optimus L7 II Dual is equipped with an attractive-looking IPS screen with a separate screen and unique color transfer, which is unfavorable for such a small thing. In most details and on both sides of the fonts, pixels can be viewed at a density of 217 ppi, of course, it is possible, however, in the dark picture there is no need to be careful about the unpalatable friability. In numbers, the physical parameters of the smartphone screen are as follows: screen dimensions – 57×94 mm, diagonal – 109 mm (4.3 inches), separation – 800×480 pixels.

You can only manually adjust the brightness of the LG Optimus L7 II Dual display; there is no automatic option. Multi-touch technology allows you to process up to ten documents simultaneously, which is confirmed by tests. Є a proximity sensor that blocks the screen when you bring the smartphone close to your ear. Devices can also keep your eyes on the other front camera and keep the screen dark for an hour until you look away.

A detailed examination of the prevailing trends of the regions is carried out by the editor of the sections “Monitory” and “Projectors and TB” Oleksiy Kudryavtsev. We bring this expert thought about the screen of the completed test image.

The smartphone screen is covered with a glass plate with a mirror-smooth surface and, judging by the image in the new bright light, does not have an anti-glare filter. On the outer surface of the screen there is a special oleophobic (fat-resistant) coating (not as effective), which means fingerprints come off easier and are less flexible at the bottom of the edge.

With manual bathing, the maximum value was 380 cd/m2, the minimum - 7 cd/m2. The brightness is high, so that during the day on the street the screen becomes less readable, and the brightness is reduced, allowing you to comfortably use the device in the dark. At any brightness values ​​of the modulation, the backlight is silent (no more than 100 kHz), then the minimum is a day.

Which smartphone has an IPS matrix installed? The microphotograph demonstrates a typical IPS subpixel structure:

The screen can be viewed well without inverting the colors and without a significant change in colors, which is a great benefit when looking at a perpendicular angle to the screen. The black field with an enhanced diagonal brightens greatly, but loses a close to neutral gray color. When viewed perpendicularly, the evenness of the black field is average - on the borders of the screen there are local sections with increased brightness of the black field. The contrast is high – close to 950:1. The hour of play during the black-white-black transition is 21 ms (10.5 ms on + 10.5 ms on), the transition between the two tones is 25% and 75% (for the numerical values ​​of the color) and back the total takes 35 ms. The gamma curve was generated at 32 points and revealed a slight decline in the light areas, and in the shadows the brightness should increase significantly. The indicator of the approximated static function is 2.21, which is actually older than the standard value of 2.2, but at which the real gamma curve clearly deviates from the static value:

Color color close to sRGB:

The spectra show that the light filter matrices gradually mix the components one by one:

Through the war of colors, this screen's richness is close to that of nature. The balance of shades on the gray scale is imperfect, since the color temperature of the object is beyond the standard 6500 K. However, the variation in the spectrum of an absolutely black body (delta E) is not very large, and the variation in color temperature and delta E is still m is small, which has a positive effect on the visual color balance. (The darker areas of the gray scale may not be correct, since the balance of colors there is not of great importance, and the loss of fade of color characteristics at low brightness is great.)

The overall screen does not have the best color rendition and a relatively high contrast, but other characteristics are in the middle.

Sound

Nothing special can be said about the sound of the LG Optimus L7 II Dual. The middle of the sound is the sound of the Dinamikiv, the middle of the gochanist, the worship of the low frequencies, the yak і і і І І і Р Ін іven, the maximum rowen gutnosti is so shortly able to characterize the soundsista of the pre -saberujuyuvyu an album. Tim is no less, his functions of the loud and loud resentment of the dynamics are completely decent. The speaker’s language is well marked, the timbre of the voice and intonation of familiar voices are recognized.

Camera

LG Optimus L7 II Dual is equipped with two digital camera modules, like most current smartphones. The front VGA camera here has a simple 0.3-megapixel module and can be taken from just one separate area – 640×480. The clarity of the photographs can be judged by hovering a test photograph below.

The main rear camera of the LG Optimus L7 II Dual is equipped with an 8 MP sensor with rear LEDs. Behind the scenes, the camera takes pictures in standard mode with a maximum resolution of 3264×2448 – such pictures will be captured by the LG Optimus L7 II Dual with settings out of the box. To view photos with widescreen aspect ratios, you must manually switch to the 6 MP split resolution, and the photos will be output in the 3200x1920 split frame. Below is a number of test images collected from different minds from different departments in automatic mode.

	The sharpness is too bad, and other objects are filled with noise.
	Sharpness drops to the right edge of the frame.
	The box and the inscriptions are well-made, and the axis of the tree is uniform.
	The other numbers on the shield are clearly marked; other car numbers are not visible.
	The camera chooses the exposure poorly, but again due to noise.
	Zagalom allowed for a hint of disgrace.
	There are a lot of writings in the background. The grass in the great vista still resembles grass, and trees are similar to trees.
	Macro tsikave, that y botsi turned out bad.
	Just change the lighting a little, as the camera raises the light sensitivity, and the noise immediately starts to pop up.
	The attached camera takes bad pictures.
	The text is heavily distorted.

At first glance, the camera looks bad, but then people start thinking that maybe it’s not 8 megapixels. However, plenty of photographs confirm the camera parameters. Perhaps, as in most cases, the main problem is with the program. Perhaps the camera also has an extremely loud sensor, which sometimes gives away an even worse picture from the optics. Of course, this can explain the unevenness of sharpness and resolution across the image field.

The camera does not know that high light sensitivity values ​​are contraindicated. And the highest values ​​for it start at ISO 300, as in another photo of ashberry. Align this photo with an ashberry nail (shaded 1/100 s, ISO 300), the traces on the street, and the photo with the anniversary (vintage 1/50 s, ISO 200), the traces in the room. Of course, the composition with the anniversary itself is bright, and there are not a lot of natural colors in the photo, but still - what a great difference in noise! The text of the LG Optimus L7 II Dual also did not achieve success. Knowing that the font is different, we risk not reading the text later.

The camera is ambiguous. It's bad enough to deal with the details, so it's no good for a good documentary. Noise control is poor, so I can’t claim the title of mystic. You can consider it a bad camera for capturing large, well-lit objects, because its range is extremely stagnant. The camera is not so bad, but it is even more vibrant to the minds of the wife.

The smartphone can record video that is not available in Full HD, nor in separate sources at 720p. The maximum resolution that the LG Optimus L7 II Dual video camera can take is 720x480 pixels, and this format is configured as TV mode. Afterwards, the camera records video from a VGA-separated area (640×480). It is clear that this smartphone is not intended to be a camera phone, but in their marketing messages to people, LG representatives still want to include the ability to capture the minds of insufficient light among the smartphone’s specific functions (they are respectful of the functionality of the sensor at the back BSI-listed). However, this is quite logical, because when the separation distance is reduced, the noise is not visible, and the camera cannot detect color noise on 8-megapixel photographs. Below is a pair of test rollers, taken with maximum adjustments and with the least amount of separate parts that are installed at the factory after cleaning. Videos are saved in MPEG-4 container (AVC video, [email protected], sound - AAC LC, 96 Kbit/s, 44 kHz, 1 channel).

• Video No. 1 (3.19 MB, 720×480)
• Video No. 2 (3.32 MB, 640×480)

The camera setup is standard for smartphones based on the Android operating system. The icons are clearly marked and large, in the brightest light they are completely visible. The settings have the ability to link geotags, add graphic and color effects, select a scene, panoramic capture, serial capture and voice control by releasing the shutter during the hour of washing out the different layers, from “what” to National Korean "Kimchi". The shutter sound, unfortunately, as in many Asian devices, cannot be turned off. There are a number of options available to control the storage of the LG Optimus L7 II Dual. You can do this either by tapping on the icon on the screen, or by pressing the hardware key, which in photo mode turns into the shutter button. The shutter release function can also be programmed with an additional hardware key, which is configured in this device, for obvious reasons, and it’s also a waste of money, since the volume button is used for photography. ku. On the positive side, you can note the ability to take a photo while recording a video.

Software security

LG Optimus L7 II Dual runs on the Google Android software platform version 4.1.2. On top of the standard OS interface, the company installed a graphical interface called Optimus UI version 3.0. The shell here is absolutely the same as in most of the LG smartphones we tested earlier - for example, the old Optimus L9.

At the time of writing, the firmware of our test copy was updated to the latest version. At this point, it is important to note that with the new firmware version P71510f, the smartphone interface will begin to work much faster and smoother. Now the programs are opening faster, and the pressure has never happened. So, it’s only good news that after purchasing the LG Optimus L7 II Dual, you will start to install the updated software with this device (the update “arrives on the winds” in a number of stages).

There are a lot of additional add-ons, as is traditional for LG, and most of them, again, are familiar to us from the previous models of the L-Style series. The most important of them are a file manager, a task manager, an add-on manager, a backup program, and a dictionary-transfer with one dictionary-free dictionary. And the cost axis for full-time work with office documents here is a lot of hassle.

Telephone and communication

The smartphone operates as standard on current 2G GSM and 3G WCDMA networks, the device does not support fourth-generation networks (LTE), and also reduces the ability to communicate over short distances using additional NFC technology. The radio part of the smartphone being tested is stable, there were no significant losses in the signal and no loss of communication with the operator. The marking of keys, numbers and letters in the number dialing and virtual keyboard for dialing SMS notifications must be completed manually.

Mimovilnykh rezavantazheniya/vyknen for an hour the test was not taken care of, except once it crashed so that the device froze. The power supply was simply overloaded, although in particularly important situations the battery could be damaged. You can independently reactivate your smartphone by pressing the life key and selecting the appropriate item in the drop-down menu. There is no such light indicator of the inputs of the smartphone, which, due to the number of backlit buttons, can be recorded in the unique minus of the device. Everything about the buttons is completely rotten: here you can suddenly press the one that indicates the change of the priority SIM card, and then click from a completely different number from which you chose to call Anyway, in the dark, be especially careful sim device.

In addition to the special button for quickly changing the priority SIM card, the implementation of work with two SIM cards is standard: only one can be active, only one of the cards operates in 3G mode, the other is surrounded by 2G, although the You can change card modes without physically changing slots, It’s just that the 3G mode can only be supported by one of them.

Productivity

The LG Optimus L7 II Dual hardware platform will be based on the Qualcomm MSM8625 single-chip system (SoC). The central processor has two ARM Cortex-A5 cores that operate at a frequency of 1.0 GHz. The RAM of the device is transferred to 768 MB, and the storage space available for storing powerful files is approximately 1.7 GB from the nominal value of 4 GB. It is possible to expand flash memory using microSD cards, and the USB host mode is not supported by the smartphone.

All the numbers we collected during testing of the LG Optimus L7 II Dual smartphone in popular benchmarks have been compiled into a table for ease of reference. The productivity of the hardware platform of the monitored word was found to be low in all tests, as additional comments here, perhaps, say - the numbers speak for themselves.

While the graphics subsystem is being tested in the cross-platform 3DMark test, in new testing it also showed a far from record result - 2441 points.

In addition to the mysterious result in SunSpider, the newcomer LG entered on the level of the most advanced solutions of competitors, the results of the tests were the same: for the LG Optimus L7 II Dual, the platform with low productivity was tested, and for the tests this smartphone would definitely lose to any flagship of the past. u.

Created video

To test the “omniversity” of created videos (including support for different codecs, containers and special capabilities, such as subtitles), we have selected the widest possible formats, which will form the bulk of the content found in Merezh i. Please note that for mobile devices it is important to support hardware video decoding on the same chip, since it is often impossible to obtain current options for devices without processor cores. It’s also not possible to decode everything from a mobile device, since the leadership in flexibility lies with the PC, and no one is going to disgrace it. All results are compiled into a single table.

Format	Container, video, sound	MX Video Player	Standard video player
DVDRip	AVI, XviD 720×400 2200 Kbit/s, MP3+AC3		appears from the shadows
Web-DL SD	AVI, XviD 720×400 1400 Kbit/s, MP3+AC3	appears with minor touches	appears from the shadows
Web-DL HD	MKV, H.264 1280×720 3000 Kbps, AC3		not pretending
BDRip 720p	MKV, H.264 1280×720 4000 Kbps, AC3	appears with noticeable shadows	not pretending
BDRip 1080p	MKV, H.264 1920×1080 8000 Kbps, AC3	appears with noticeable shadows	not pretending

In addition to synthetic benchmarks, video tests that also showed a lack of productivity for the device are disappointing. One thing is that you won’t be able to score 10 thousand points, and the whole thing is that a film made through a smartphone is not suitable for such a popular leisure activity among the rich. However, here you need to make sure that the separate part of the screen on the smartphone is only 800×480, and if you display the video on the other display device of the LG Optimus L7 II Dual, it’s still not the same, then in principle All you need to do is open SD-enabled files. Here, according to our tests, not everything is perfect, but still, when you select the right player and ripple, you will be able to enjoy the series of your favorite series without serious complaints about the bitterness.

Hour of autonomous robot

The capacity of the battery installed in the LG Optimus L7 II Dual is 2460 mAh. Prote, to our surprise, has demonstrated only an average hour of autonomous operation, similar to other tests we have previously tested with smartphones in similar standard modes of operation.

	Battery capacity	Reading mode (2 years)	Video mode (2 years)
LG Optimus L7 II Dual	2460 mA year	13%	23%	5 year 00 xv.
Huawei Ascend Mate	4050 mA year	11%	17%	5 year 00 xv.

Continuous reading with the FBReader program at a minimum comfortable level of brightness (brightness was set to 100 cd/m²) for 2 years consumed 13% of the full battery charge, and for a two-year review of YouTube videos at a high level bones (HQ) via home Wi-Fi -Fi Fi device has consumed 23% of battery capacity. And even with maximum intensity in the continuous 3D game mode (100% brightness, 60 fps), which we tested using GLBenchmark, the smartphone was wiped longer than usual - as much as 5 years. Fully charging the LG Optimus L7 II Dual takes a long time and takes about 2 years 50 minutes.

Here we are interested in drawing attention to the fact that the low-productivity platform of this smartphone turned out to be not very economical: when equipped with an LG Optimus L7 II Dual processor, it lasts about the same as current flagships with a similar battery capacity Yes, and the smaller screen does not help me. the brightness of the matches was normalized). The only gaming mode for this smartphone is 3D games with maximum brightness of the screen, and flagships with intense 3D acceleration, high separation of the display and a large bright screen are “squandered” by Mitevo, and the hero of ours is like the hero of ours commercials, everything works pratsyuє.

Pouch

At the moment, the official price for LG Optimus L7 II Dual is set at 10,990 rubles in our stores. For such a simple smartphone, the price is insanely high. There are no luxurious materials to the body, no hard hardware filling here, and the doors of the “blunders” of the distributors, such as buttons that cannot be illuminated in the dark, add to the negative. However, for the sake of fairness, it is important to respect that the phone has its advantages. In front of us, there is a bright silk screen with bright colors and a rich transmission of colors. The advantages include an even compact body with a screen measuring more than a few inches, as well as an additional hardware key with a function that is indicated. And yet, the price for this device is very high, installed by LG in our region, it is important to clarify that we would like to get this smartphone on our shelves at a more affordable price, which is consistent with the product.
