It so happened that users of Meizu M3s have a massive problem when the Home / mTouch touch button does not work: the scanner and the "back" command do not work, there are also arbitrary reboots. There is a problem with the appearance of red stripes on the display, this is described in the article.

The reasons for the refusal of the button, as practice shows, can be different:

• crookedly installed firmware image
• moisture ingress
• manufacturing defects

The first option is found on Chinese versions of smartphones (usually purchased from Aliexpress), when an unofficial Global firmware image is installed on the smartphone.

Solved programmatically: install the Chinese version of Flyme firmware 5.1.5.1A with data clearing, check the button, if it works, then go to the official Global firmware by changing the id ()

When moisture or condensation gets in, oxidation is created in the button, as a result of which it refuses to work.

In some cases, disassembly helps, as well as cleaning the button and contacts from oxide. With this problem, it is better to contact the service center, especially if the smartphone's warranty has not expired.

As for the factory defect, this is a massive problem that appears some time after the purchase. The solution is to replace the button.

Is your smartphone under warranty? Then be sure to contact the seller with the warranty card or directly to the service center servicing the warranty.

If the smartphone was bought from China and there is no guarantee for it, then you have 2 options:

• carry to service for paid repair
• change the button yourself by ordering from China.

Important! There are 2 versions of buttons: "VF SF" and "VGS". If you install the VF FS button, over time the defect may reappear, and with the VGS version (judging by the polls on w3bsit3-dns.com), the problem appears extremely rarely.

You can buy the VGS version button on Aliexpress, for example, from this seller (LINK). This vendor will include the required tools with the order.

Replacing the button is not a complicated procedure, below we attach the instructions:

All actions you do at your own peril and risk !! We recommend contacting a specialized service center!
Before starting disassembly, you need to turn off the smartphone and remove the SIM card tray.

One of the weak points of Meizu smartphones is the fingerprint scanner (mTouch). Some owners complain that this button does not function immediately after purchasing a mobile device. For others, it fails after a certain time. If the phone is under warranty service, then the problem of non-working mTouch is solved by handing over the device to the service center. If there is no warranty, you can try to fix the defect yourself. Let's take a look at what to do if a fingerprint does not work on Meizu M3 Note, M3 mini or other gadget of this manufacturer.

Possible reasons for the failure of the mTouch key on Meizu

In all Meizu smartphones, the fingerprint scanner is built into the proprietary mTouch touch-mechanical button, which has three functions:

If the fingerprint button and the "Back" function do not work on Meizu M3S, the reason may lie in the following:

• mechanical breakage of the key;
• penetration of moisture under the mobile phone case;
• software malfunction.

Mechanical faults mTouch on Meizu

If all three functions ("Back", "Home" and "Scanner") stop working on your device at the same time, most likely, the mTouch button is simply out of order. A similar problem can show up after a strong blow, drop or wet phone. However, sometimes a malfunction occurs without any apparent reason.

If the warranty period for Meizu M3 has not yet expired, it is better to take it to a service center. Otherwise, you can change the broken key yourself:

If the cause of the malfunction is the ingress of moisture on the phone, after disassembling, carefully inspect the key contacts. If oxidized, clean them with alcohol and a soft cloth.

Troubleshooting Meizu Software Issues

If on your Meizu M3 Mini the fingerprint scanner and the "Back" function unexpectedly stopped working, you should not discount the software crash. On Android devices, such malfunctions occur quite often. To eliminate them, you will need to reset all settings on your mobile phone to factory settings.

To perform a hard reset, you must:

After a complete cleaning and reboot, the mTouch button should return all functionality.

The hard reset procedure removes not only all settings from the phone, but also user files located on the internal memory of the gadget. Therefore, before activating it, save important information to an external drive or computer.

If you bought Meizu on AliExpress or another Chinese platform and the fingerprint scanner does not work on it from the first days of operation, most likely, the smartphone was originally developed for the Asian market and it has local firmware or, at best, a Russified global image. To check the firmware, you need to go to the About phone section and see what is written in the Flyme version line. If the last letter is A, U, or C, then it is Chinese firmware. The global version ends in G or I.

To fix the problem, you will need to install the global firmware by changing the ID. This is done as follows:

1. Link your mobile phone to your Flyme account. This is done in the "Accounts" section.
2. Unblock root access in the "Personal Settings" tab.
   
3. Install the SuperSU program for managing Superuser rights and Terminal Emulation on the device.
4. Load the chid.sh script to the root of the internal memory. It is he who changes the old ID to a new one.
5. Also download the latest global firmware for your Meizu model. The file should be named update.zip.
6. Start Terminal Emulation and enter two commands in it via Enter: "su" and "sh / storage / emulated / 0 / chid.sh".
7. After successful ID change

The main reason why home button stops working in Meizu M2 or M2 mini - moisture gets into it. Perhaps you spilled water on this button or just got caught in the rain - it doesn't matter. After getting moisture, it will no longer work normally. It is very strange that the manufacturer did not take care of at least some kind of moisture protection.

Inoperability of the Home button manifests itself in different ways. It may fail completely, the sensor may stop working, while the presses work normally, or vice versa. I had the following case: the Home button on level ground in my Meizu M2 Mini started to work incorrectly. Touches didn't work at all, but push did. I already thought it was a problem with the Android operating system and decided to do a factory reset, but it didn't help.

My solution to the home button not working in Meizu M2 Note / Meizu M2 Mini.

The hairdryer solution that I saw on YouTube helped partially, the problem returns 5-10 minutes after drying. I found the solution to this problem very simple - using regular alcohol and a cotton swab, gently wiped the Home button around the entire perimeter, while pressing it so that some alcohol got inside. The bottom line - for more than two months now, the Home button in my Meizu M2 Mini has been working properly.

I just suggested one of the options for fixing the problem of the broken Home button in Meizu M2 Mini. If you make it worse, it’s not my fault.

If my solution did not help you, do not panic - try returning the phone to an authorized service center, perhaps you can replace the home button under warranty. If they refuse to do this, or you do not have an official guarantee for the device, then there is only one way out - buy a home button for Meizu M2 on some Chinese website, for example on Aliexpress, good

Meizu conquered the market with its affordable and fairly productive gadgets, however, not all users of new smartphones were satisfied with the build quality and operation of the devices after purchase.

One of the most popular problems is the touch button on Meizu M3 s stopped working (although this also includes Meizu M3e, Meizu M2, M5 and other models).

Mechanical and movable parts are always a weak link in any device, so eminent manufacturers try to anticipate possible problems and maximize the MTBF of all buttons on devices.

What are the reasons for the button breakage on the Meizu M3

For example, Apple, starting with the iPhone 7, went even further and replaced the mechanical button with a fully touch button with active feedback (to emulate a real press).

But be that as it may, Meizu was not able to pay due attention to its devices and therefore the following complaints are encountered on the network:

• The sensor on the button of the Meizu phone does not work immediately after purchase (especially important for remote sales through Aliexpress, etc.);
• The button stops working after several months of use;
• The button does not work the first time after pressing;

Failure most often occurs after the device falls or falls into water.

If everything is clear at once for mechanical damage, then the causes of other malfunctions may be different.

For example:

• Water ingress (after falling into water) or condensation (operation in high humidity with a sharp change in ambient temperature);
• Quick wear of the button (unlikely, but possible), this also includes the low quality of the original components;
• Software error (bugs in the device firmware);
• Poor soldering of the Meizu M3 Home button cable (the so-called "head on pillow" effect, which is characteristic of a large number of modern digital devices due to the peculiarities of factory soldering).

Replacing the Home Touch Button on Meizu M3 Smartphone

Of course, the first thought that comes to mind in case of any breakdown of a complex device is to contact an official service center, and if the warranty is still valid, the seller or manufacturer will eliminate the defect completely free of charge, and also keep the warranty until its full expiration.

However, it is not always possible to contact such a center (not within reach, the product was bought without a guarantee, etc.).

If there is no way to visit the service center, there is only one solution:
the problem with the Meizu M3 home button is solved only by replacing it completely.

Below we denote the algorithm of work with our own hands.

Buying a button.

There are 2 versions on sale - VF SF and VGS, the latter is more reliable according to user reviews, so you should choose it. The cost at the moment is about 600 rubles.

Disassembly of the phone.

1. First of all, 2 screws are unscrewed from the bottom of the case along the edges from the charging connector.
2. The back cover is removable from the edge with the designated screws.
3. Another 6 screws are unscrewed under the battery on a plastic insert.
4. After removing the insert, access to the board opens. The loops are disconnected, the retaining screw is unscrewed, the board rises.
5. A touch button is mounted under the board. It is attached with 2 screws to the body of the smartphone, the ribbon cable is connected to the main board.
6. The old button is removed and replaced with a new one.
7. The screws are unscrewed, the cable is disconnected. The new one is mounted in the reverse order.
8. The smartphone is going back.
9. The performance check is in progress.

If you are not sure of your actions, you can contact the nearest repair shop with your own button. The procedure will cost about 500 rubles more.

Troubleshoot button problems without replacing

What should you try to restore the device's performance on your own without replacing the Home touch button?

If the phone was purchased immediately with a defect, in some cases flashing or resetting the phone's settings may help.

It is important to remember here that in the process of flashing the smartphone may become "okay" and then no one will help you, the warranty is automatically canceled in case of interference (especially if the firmware is not official).

Information about all the procedures performed, as well as stable firmware versions, can be viewed on specialized resources (for example, the w3bsit3-dns.com forum, or on the official website), there you can also familiarize yourself with the experience of other owners with similar problems.

VIDEO INSTRUCTION

If the flashing did not help, or the defect appeared after several months or even weeks of use, the most likely the reason for the breakdown of the Home button on Meizu - moisture ingress (in some cases moisture can get in even without the smartphone operating in the rain or falling into a puddle).

1. You can try to eliminate this defect by drying the phone with an ordinary hair dryer (just not a construction one, it gives out too high a temperature).
2. Some users manage to develop the button after drying (due to repeated pressing in a heated state, warm air comes out along with excess moisture).

If both of the above methods did not help, you can try to disassemble the phone yourself and wipe the button with alcohol (something sticky that could not be blown out by a hairdryer could get in).

Another alternative solution is to replace the functions of the hardware button with a soft button (a special widget will be displayed on the smartphone screen, activated in the phone settings in the section with accessibility features).

However, the fingerprint scanner will still be unavailable, which deprives the phone of some of the important functionality. This solution can only be temporary (before going to a service center or workshop).

Button not working in Meizu M3s - what to do?

The Meizu M3s smartphone has become widespread among fans of modern gadgets and mobile phones. However, some time after the start of sales, many owners began to face the problem of a non-working mechanical Home button with a built-in mTouch fingerprint scanner. Thus, the functions "Back", "Home" and unlock the screen with a fingerprint became unavailable.

In this article, we will tell you about the causes and solutions to this problem. And if you urgently need to fix your smartphone, or any other device, we recommend contacting the service center https://m-service.com.ua/.

So, there may be several reasons why a mechanical key in Meizu M3s may fail. The most common ones are as follows:

Incorrect firmware installed;

Penetration of moisture inside the smartphone;

Factory defect or mechanical damage.

The first case - an incorrect firmware version, as a rule, is found on Meizu M3s smartphones imported from China without certification. Such devices are usually purchased from Chinese online stores - Aliexpress, TaoBao, etc. The smartphones have Asian version of the firmware, while the official Global firmware is needed.

The solution to this problem is very simple - you need to install the Chinese version of Flyme 5.1.5.1A and clear all data. Next, check the button for functionality. If the problem is solved and the mechanical key works, you need to switch to the international Global firmware by changing the ID

The next problem is related to the ingress of water, moisture or condensation into the device, with the subsequent oxidation of the mechanical key (possibly other parts of the phone), which is why the button refuses to work in the future.

In this case, disassembling the smartphone and cleaning the button from the formed oxides can help. However, if you are not "strong" in disassembling mobile phones, it is better to contact a specialized service center (one of which we recommended above).

It is very good if the Meizu M3s smartphone is still under warranty. In this case, it is better to contact a certified service center, where diagnostics and key replacement will be carried out free of charge. However, users of Meizu M3s phones focus on the fact that the problem begins to appear 1 year after purchase, which means the warranty expires in this case.

Please note that if you decide to repair yourself, you will need a new mechanical key. You can buy it either in the online stores of service centers (by the way, in"M-Service" such a button is in stock), or purchase directly from China viaAliexpress ... When buying from China, pay attention to which key you are purchasing. There are two versions "VF SF" and "VGS". In the first version of the button, according to customer reviews, the defect may appear after some time, and the VGS version does not have such a problem.
