Due to a fall on a hard surface, a manufacturing defect or other unpleasant situations, the display of a mobile device may stop functioning, and accordingly, controlling the phone becomes impossible. In such circumstances, you need to know what to do if the touch buttons or screen on your Xiaomi smartphone do not work?

The most effective option is to use the services of a service center, which have a high cost, since touchscreen repair in current device models involves the entire display. However, if there is no urgent need for repairs, but the gadget is required for current use, it is worth using practical recommendations.

How to check the screen sensor

To test the sensor on a smartphone, follow the steps below:

“Settings” - “About phone” - activation of “Kernel version” - in the engineering “Touch Sensor”.

Then, slide your finger across the screen. Once you find dead spots, turn on the mode that allows you to operate the device with one hand. If there are areas where the sensor is not working at all, you will most likely have to replace the entire module.

The following method will help if Xiaomi starts to glitch after a fall.

Xiaomi redmi note 4 buggy sensor freezes

Unfortunately for everyone, a problem with the sensor on Xiaomi Redmi Note 4 smartphones is by no means a rare phenomenon. The device’s display may light up on its own or, conversely, not respond completely to touching the screen, or in certain parts of it.

Users have encountered the fact that the touchscreen does not work every time, or the device does not respond to commands at all when pressing the touch “buttons”. If you also encounter the problem of a screen malfunction, let’s try to figure out the reasons and ways to fix it.

Connecting a mouse via OTG

The OTG function is designed to use a special cable through which you connect both external drives and a mouse or other peripherals. Android software allows, after connecting a wired or wireless mouse, to display a pointer on the screen, allowing you to control your smartphone in the same way as a regular computer. The technique is relevant for preparing the phone before contacting a service center, since in this way you can exclude all data that should not be seen by the technician.

↑ Failure in technical terms

As practice shows, most often the cause of spontaneous operation of buttons on the touch screen is a hardware failure. As a rule, a crack in the screen leads to a break in the mesh, so the failure of the part located above the crack is most often observed.

If, after its occurrence, moisture containing a conductive substance, for example, apple juice or another similar liquid, gets on the screen, then conductivity will appear and may occur in the wrong place. In this state, absolutely any buttons located, so to speak, in the damage zone can be triggered.

Also, one of the reasons for false operation of buttons on the screen may be various contaminations. As a rule, as a result of prolonged use of a smartphone, a large amount of foreign substances, including biological ones, accumulate on the screen. Due to their large accumulation, false positives may well occur.

In addition to contamination, there is a possibility of false operation due to mechanical damage in the connector. If the cable is dropped or even slightly damaged, such problems may well manifest themselves in the form of unauthorized activation of various functions on the device screen.

Such a defect can only be eliminated by replacing the display module assembly, because it cannot be repaired.

Reset your phone to factory settings

Every digital device has a subsystem that regulates system boot, selects boot media, and sets parameters for connected devices. Your smartphone has it too. And we will use it to restore the device settings to factory settings if the sensor in your mobile phone is faulty. And also the previous methods did not help eliminate the problems with it.

Since now we are talking about any phone model, you will need to independently fulfill all the conditions after which you can enter the “Recovery” menu:

Condition:	Explanation:
To get into this mode on the smartphone, you need to press two or three buttons at the same time and hold them until you see a menu that is unusual for your device.	This could be the power button pressed together with the volume up button. And the volume down and power button. You should experiment with combinations.
Before trying, be sure to turn off your smartphone.	You can launch the menu only when the smartphone is not working.
Connect the smartphone with the non-working sensor via USB to the computer and transfer the data to its memory.	If you have access to system folders, gallery, make copies of important files.

Only after all conditions have been met, launch the Recovery menu:

When the menu appears, select “Wipe Data/Factory Reset”;
Read also: It is impossible to connect the camera, close other Android applications
On the next window, select “Delete all user data”;
Wait until the recovery process for your smartphone is complete.

The mobile phone memory will be completely cleared. Perhaps the problem was at the software level. And after restoring the system settings, there is a chance that the device will again work stably and without glitches on the screen. Turn on your phone and check if the sensor responds to your touch. If, after applying the methods described in this article, your device does not work correctly, we recommend contacting service. Because most likely the problem lies deeper. And you can’t do without inspecting the device by competent people.

How to choose?

The touchscreen on my Redmi 6a stopped working, the screen lights up, there is an image, but it does not perceive touches on the screen. There is a crack on the protective glass after an impact. Does broken glass affect the sensor?

I spilled water and it got on the redmi 6a display, half of the sensor turned off and the rest doesn’t work. Why did this happen, because glass does not allow liquid to pass through.

The touchscreen is glitchy and reacts to touch the second time; multi-colored stripes have appeared. Is it possible to repair a xiaomi display or does it need to be replaced?

Repairing the sensor cost me 1,500 rubles, which I don’t think is a big price. This device module costs much more on the Internet. The cable was broken and they re-soldered it.

Repair xiaomi redmi 6a, the sensor does not work or is buggy.

The most fragile part of a phone is the screen. In Redmi 6 it is glued to the body, and in most cases there are silks into which water can easily penetrate.

Oxidation forms on the open contacts of the circuit, and the connection point of the cable malfunctions. Repairing the sensor in this case is limited to cleaning the contact group of the plug with alcohol, but before doing this, you should disconnect the battery.

A very discharged smartphone will not be able to turn on the backlight. This is usually indicated by a red indicator on the device panel. It is not the phone monitor that should be repaired, but everything related to charging.

The gadget slows down greatly, reacting to touch every other time. The operational storage of information can be constantly full, like the main memory, due to the fact that new information cannot be processed and therefore Xiaomi begins to slow down greatly. You need to free up memory, remove unnecessary programs through the application menu.

If the touchscreen is damaged, has a crack, or does not respond to touch. Most likely this module needs to be replaced. Unsticking the display and separating the touchscreen is not an easy task. With the help of wire and a hair dryer, peeling occurs, after completion, a new one is glued, and that’s it. The price for this part is from 500-1500 rubles, and the screen from 2000-4500 rubles.

The touchscreen on the smartphone freezes in one place

People encounter this problem quite often. When typing text or numbers in one specific place, the screen does not want to work in normal mode. Letters may not be pressed correctly. Instead of one letter “A”, press the adjacent “P” and the like. Such cases are still typical if you have been using the device for more than a year. The reason may lie in the smartphone battery.

The surface of the battery may be swollen. After some time this happens to them. Bloating should not be clearly visible. It can be determined by removing and placing the battery on a flat surface. Press on two opposite corners of the battery to see if the bulge can be detected. A working battery should lie flat on a flat surface and not dangle. And since there are already bulges on it, with one side it presses on the sensor from the inside. What could be causing poor screen responsiveness?

Also check whether a wire or an extra object has gotten under the battery. Any unnecessary or interfering objects can put pressure on the screen from the inside. You won't be able to replace the battery right away. And for a few days you can do a little trick. It consists of incomplete installation of the back cover. Hang it on the top mounts. Don't press down the bottom ones. So as not to pinch the convex battery.

Presses the power button (on, lock)
Hold for 20 seconds, usually this time is enough
As soon as Mi Logo appears on the screen, release the button
If nothing happens, then try holding it a little longer, 25-30 seconds.

The same method is suitable for both Redmi 3s and any other Xiaomi or Android phone.
