The only physical navigation key in Meizu smartphones is combined: it combines mechanical and touch control methods. She is responsible for the following options:

• recognition of the owner's fingerprint pattern and further unlocking of the screen;
• "back" command;
• return to the main screen.

The first two functions are implemented on the key sensor, the last one is carried out by its mechanical component. If the key has ceased to perform its functions, this signals the owner that a breakdown is taking place, and may be of a systemic or mechanical nature.

The most common causes of problems

System failures are:

• single short-term braking;
• incorrect settings;
• problems in installed version updates or firmware.

Mechanical factors:

• penetration of moisture and condensation into the phone body;
• impact, fall, squeezing of the device.

Possibility and methods of repair

Elimination of system defects

Before you start fixing defects in the system, it is advisable to create a copy of all important information.

When the touch button of the Meizu M3 s does not work, the user needs to at least temporarily be able to control the phone during repair procedures. To do this, you can replace the failed main key with a special virtual analogue. In the settings menu in the accessibility section, activate the mTouch emulator. The widget appears at the bottom of the screen and performs all the functions of the main button, except fingerprint identification.

At first, it’s wise to simply restart your smartphone to clear all assigned tasks, a large number of which may have caused the slowdown.

Incorrect phone settings are checked in the corresponding section of the menu, set required parameters. If the fingerprint button does not work on the meizu m3s, assign it again or perform full reset all settings.

You can try to calibrate the key using the smartphone's engineering menu, but this will require special knowledge.

An incorrectly functioning update or firmware is replaced with a working version, or a return is made to the previous one, which was fully functional.

If the result is not achieved, and the meizu m3s button (print) still does not work, proceed to correcting mechanical failures.

Smartphone electronic component repair

If a key does not function due to damage in the device's hardware, it can usually only be fixed by completely replacing the button module.

When the culprit of the failure is a small amount of moisture that has entered shallowly into the gap of the key, and the user notices this at the same moment, he can make an attempt to revive the gadget. It is necessary to immediately turn off the smartphone to prevent oxidation from spreading to nearby electronic components. Then take a cotton swab and, lightly moisten it in alcohol, wipe the key groove with it. Alcohol will dry moisture that is close to the surface, but will not have an effect on moisture that has penetrated deeper. The situation when the meizu m3s button does not work due to heavy wetness requires a quick complete replacement of the key module.

Damage caused by squeezing, falling, or blows can affect only some elements of the key block, or render it completely unusable. It is possible to replace only one of the elements of the entire module, but it is impractical due to the cost and time required to select a compatible spare part. In such cases, it is cheaper and faster to replace the entire module.

In this case, users can easily and quickly purchase a button module on the GadgetParts.ru website. You can also find any other spare parts for smartphones there. different manufacturers, tools, and detailed guides replacement for each spare part.

Meizu has conquered the market with its affordable and fairly productive gadgets, however, not all users of new smartphones were satisfied with the build quality and performance 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 moving parts are always the weak link in any device, so renowned manufacturers try to provide possible problems and maximize the time between failures of all buttons on devices.

What are the reasons for the button failure on Meizu M3

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

But be that as it may, Meizu was unable to pay due attention to its devices and therefore there are complaints of the following nature online:

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

Breakdown most often occurs after the device has been dropped or dropped into water.

If everything is immediately clear about mechanical damage, then the causes of other malfunctions may be different.

For example:

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

Replacing the Home touch button on the Meizu M3 smartphone

Of course, the first thought that comes to mind when a complex device breaks down is to contact the official service center, and, if the warranty is still in force, the seller or manufacturer will eliminate the defect completely free of charge, and will also maintain the warranty until it expires.

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

If it is not possible to visit a service center, there is only one solution left:
The problem with the Meizu M3 home button can only be solved by completely replacing it.

Below we outline the algorithm for doing it yourself.

Buy button.

There are 2 versions on sale - VF SF and VGS, the latter, according to user reviews, is more reliable, so it’s worth choosing it. The current cost is about 600 rubles.

Disassembling the phone.

1. First of all, unscrew 2 screws from the bottom of the case at the edges of the charging connector.
2. The back cover is removed from the edge with the screws indicated.
3. Under the battery on the plastic insert, 6 more screws are unscrewed.
4. After removing the insert, access to the board becomes available. The cables are disconnected, the holding screw is unscrewed, and the board is raised.
5. A touch button is mounted under the board. It is attached with 2 screws to the smartphone body, the cable is connected to the main board.
6. The old button is removed and replaced with a new one.
7. The screws are unscrewed and the cable is disconnected. The new one is installed in the reverse order.
8. The smartphone is being put back together.
9. The functionality is checked.

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

Fixing button problems without replacing

What should you try to restore the device’s functionality on your own without replacement? touch button Home?

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 during the flashing process, the smartphone may become “bricked” and then no one will help you; in case of intervention, the warranty is automatically canceled (especially if the firmware is not official).

Information about all procedures performed, as well as stable versions The firmware can be viewed on specialized resources (for example, the 4pda forum, or on the official website), where you can also read the experiences of other owners with similar problems.

VIDEO INSTRUCTION

If 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 using a regular hair dryer (not a construction hair dryer, it produces 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 could have gotten in that couldn’t be blown out with a hairdryer).

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

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

The Meizu m3 smartphone has a sensitive key with a built-in sensor under the display. It is designed to identify the owner’s fingerprint, activate a menu section, and execute the “back” command. The inability to perform these actions, or one of them, indicates that the meizu m3 touch button does not work.

There are several reasons why such a breakdown occurs.

Reasons for failure of the Meizu m3 touch button

Failure may occur due to software and hardware faults. Errors in the system shell can cause this defect when:

• the official OS update was installed incorrectly or contained errors;
• a minor shell failure occurred, such as when the system was overloaded big amount simultaneously activated applications.

Problems in the hardware of the smartphone most often lead to the fact that the meizu m3 button sensor does not work. They may be present initially, or appear as a result of improper use by the owner.

The sensitive module may have suffered mechanical damage due to:

• falling and subsequent impact of the phone;
• strong pressure;
• flooded with liquids or dampness.

Damage to your phone due to moisture can occur when you use it in the rain, touch it with wet hands, or stay in a damp room.

After these destructive influences, cracking, splitting, and oxidation of the button elements occur; in fact, the entire component becomes unusable and requires replacement.

How to fix the problem

Correction of software failures

It is recommended to start solving problems with the system by simply rebooting the gadget. If this does not help, you need to install the official update, or replace the entire system with a licensed one. In some cases, the situation can be corrected by a standard reset to factory settings. Before starting these procedures, it is advisable to make a backup copy of all valuable smartphone data.

If the button sensor of the Meizu M3 does not work, users who know how to operate engineering menu device, it is appropriate to use software key calibration. In some cases, this completely eliminates the problem.

There is an unconventional solution to the problem: the non-working module is replaced with a virtual one. This is accompanied by the visualization of a special widget on the display. This feature is available in the device's accessibility menu and can serve as either a temporary or permanent solution. It should be remembered that the virtual button cannot read a fingerprint, so this method will not work for users who use this method of protection.

Physical tampering with the hardware

When the touch button on the meizu m3 stops working due to moisture getting into the key module, you can try to eliminate the problem if you do this immediately after the incident, when the wetness is very weak. The first necessary action is to turn off the power to the phone in order to prevent oxidation from spreading deep into the digital component of the device.

Then gentle drying with non-hot air is possible. To do this, the phone can be partially disassembled if the owner has the necessary knowledge and skills. During the procedure, stimulation of the key is useful: pressing it multiple times expels heated air, which takes with it particles of moisture.

After warming up, treating the button assembly removed from the phone with alcohol may be effective, since alcohol has the ability to dry out moisture.

When disassembling the phone, it is appropriate to pay attention to the button cable - it may not be tightly inserted into the connector initially, or it may be partially disconnected due to an impact. In this case, securing it tightly helps.

If the cable has an incorrect connection, or the key module turns out to be broken, jammed, or substandard, then such defects usually cannot be repaired and the most reasonable solution is to completely replace the entire sensitive unit with a working one. You can purchase a spare element at the GadgetParts store, where prices for all products are quite affordable. Here you can also find full instructions for their replacement.

The button does not work in Meizu M3s - what to do?

The Meizu M3s smartphone has become widespread among fans modern gadgets And mobile phones. However, some time after the start of sales, many owners began to encounter the problem of a mechanical Home button with a built-in mTouch fingerprint scanner not working. Thus, the functions “Back”, “Home” and unlocking the screen with a fingerprint have become unavailable.

In this article we will talk about the causes and ways to solve 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 of them are the following:

Incorrect firmware installed;

Penetration of moisture into the smartphone;

Factory defect or mechanical damage.

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

Solving 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 is working, you need to switch to the international Global firmware by changing the ID.

The next problem is associated with water, moisture or condensation getting inside the device, followed by oxidation of the mechanical key (possibly other parts of the phone), which is why the button subsequently refuses to work.

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’s very good if the Meizu M3s smartphone is still under warranty. In this case, it is better to contact a certified service center, where they will diagnose and replace the key free of charge. However, users Meizu phones M3s emphasize 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 carry out the repair yourself, you will need a new mechanical key. You can purchase it either in online stores of service centers (by the way, in"M-Service" such a button is available), or purchase directly from China through Aliexpress . When purchasing from China, pay attention to what kind of 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, but the VGS version does not have such a problem.

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. Once moisture gets in, 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.

Home button failure manifests itself in different ways. It may fail completely, the sensor may stop working, while pressing works normally, or vice versa. I had the following case: the Home button out of the blue in my Meizu M2 Mini started working incorrectly. Touching didn't work at all, but pressing did. I already thought this was a problem operating system Android and decided to reset the settings, but it didn’t help.

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

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

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

If my solution doesn’t help you, don’t panic - try taking your phone to an authorized service center, they may be able to replace the home button under warranty. If they refuse to do this or you do not have an official warranty for the device, then there is only one way out - buy a home button for Meizu M2 on some Chinese site, for example on Aliexpress, fortunately
