- Screen damage.
- Problems with the functioning of the battery.
- Software malfunction.
- Breakage of cables or other elements.
- Problem with video controller.
Below in the article we will look in detail at each reason and ways to remove flicker.
Types of screen blinking
The difference most often is the visibility of the problem with the normal eye, as well as its frequency.
- Flicker often appears in the form of stripes or ripples, which can be barely noticeable at low screen brightness, or significant, with a change in colors, brightness in certain areas of the display, vertical and horizontal, or even mixed.
- Individual areas of the display may go dark for a short time, and this can be either one specific place or a completely unpredictable piece. At this time, the phone can either respond or not respond to presses.
- The screen can turn on or off entirely at different frequencies, and when the backlight is turned off, it will continue to respond to finger presses.
Screen damage
If the screen flickers after your phone comes into contact with water or is seriously dropped, it may be damaged. If you have this problem, contact a qualified technician at a service center. It is difficult to replace the screen yourself, because... you need to have special equipment.

Solving a problem related to the operation of the video controller
The graphics accelerator is responsible for displaying the image on the smartphone screen. It displays an image on the screen in the form of points on a plane and consists of memory, a matrix and binding. The chip is the most important component of a smartphone. The performance of graphics and, first of all, the most intensive applications and video content depends on its technical capabilities. If at least one of its internal elements fails, problems arise on the dielectric plate. The following appears on the screen:
- ripple;
- flashing;
- glow and stripes of different widths.
It is unlikely that you will be able to replace the graphics subsystem yourself without special skills. Therefore, in this case, it is advisable to take the phone to a service center.
Battery problems
Quite often, users reject all reasons other than mechanical damage to the gadget. In reality, flickering or streaking may occur due to a weak battery. The problem is related to loss of power, especially when using the battery for several years.
This option can be easily verified. All you need to do is connect the gadget to the charger and look at the screen while charging. If all problems with the image have disappeared, then the reason is related to the battery power.
The way out is to use another battery. Insert a new battery into the gadget and check if the screen flickers. It is advisable to purchase a battery in specialized stores and check its originality.
Often, Chinese counterfeits break within a month after purchase. In some situations, counterfeiting can lead to more serious damage to the gadget.

Smartphone screen flickering: reason
1. Display failure
.
I won’t hide that this was the first thing I thought about. This may be strange for some, but for me this is one of the easiest solutions to the problem. Firstly, I already have a spare display, and secondly, I can easily solve the problem myself, without the help of a service center.
2. Chip problems
, which controls the screen. This is what I feared most. I wouldn’t carry out the repairs myself at home, and I don’t have specialized equipment. In addition, the work is very painstaking. And as far as I know, this problem appears quite rarely.
3. Outdated/broken firmware
. I was hoping for this breakdown. On the one hand, I was always waiting for the moment to have a reason to reflash the gadget, on the other hand, it was not a very expensive procedure.
4. The display may flicker
if moisture gets in. I ruled that out right away.
5. Battery
.
Here's something, but I didn't attach any importance to the last point. As they say: “But I didn’t even notice the elephant.” Most likely because you are always waiting for something more serious, for which you are constantly preparing, but in the end it “shoots” in an unexpected place. And the test programs did not show any problems with it.
The reason for the flickering and turning off of the screen was the exhausted battery. Replacing that, I got rid of the problem.

Screens can be regular or touch screens and may differ in size, resolution, pixel density, and production technology. Touch screens differ in the type of touchscreen design, that is, a touch surface that responds to touch. Screen failure leads to a number of inconveniences for the user.
A dark screen, stripes on the screen, or image distortion interfere with the normal functioning of the device. To resolve any problems, you need to contact a phone repair service as quickly as possible. The longer you use a faulty phone, the more difficult and expensive it will be to repair.
Causes
The causes of screen problems can vary. Phone repair specialists note several of the most common problems:
— Malfunction of the display itself. The breakdown is usually corrected by replacing the display with a new one. Many people perform this procedure on their own, but we do not recommend interfering with the mobile phone device. This task should be entrusted to specialists who know the structure of a mobile phone well and have sufficient experience in performing such a procedure.
— Failure of the microcircuit that is responsible for controlling the screen. One of the most complex breakdowns that can occur. To carry out repairs in this case, special equipment and tools may be required, so the only right decision in this situation would be to go to a workshop, where it will be done quickly and efficiently.
— A display malfunction may be due to a firmware failure. To fix it, just perform a flashing. However, you should not perform the procedure yourself or trust your phone in the hands of non-professionals. By contacting our workshop, you will have the opportunity to correctly install licensed software on your phone and configure all the necessary parameters.

Every day, users of Android devices come to service centers complaining that their phone screen is flickering. This problem is far from new and has a number of reasons for its occurrence. Let's sort things out in order.
Despite the rapid development of mobile technologies, they have not yet made it possible to create a device that can withstand strong shocks or software failures. For each gadget, the cause of a display malfunction can be very different, so before drawing final conclusions, let’s look at each of them in more detail.
Troubleshooting if it's a software issue
- First of all, you need to check the most obvious method - restart your phone and perhaps the problem will disappear;
- Incorrect auto-brightness adjustment can cause annoying screen flickering, so turn off this feature in the settings and restart your device;
- The flawless functionality of the display is ensured by the software core. As a rule, it is initially present in the firmware installed on the smartphone, but can be added separately. Flickering often occurs after updating or reinstalling the operating system, as well as changing the kernel. In this case, the problem is resolved after installing other software that uses a working main part, or selecting a special kernel that will be ideally combined with the hardware or software.
- Although individual software components may be configured correctly, incorrect customization can also cause significant inconsistencies in functionality. The xiaomium.ru project recommends using only proven firmware designed for a specific model.
If all else fails
Excluding problems in the software, you should diagnose the hardware of the smartphone.
In most situations, display failure is caused by significant physical impacts, for example, a strong fall of the device onto a hard surface from an average height, as well as its fall into water or use in the rain. As a result, the stable operation of the backlight is disrupted, which begins to flicker cyclically and the entire interface acquires a rippling effect.
- If the smartphone was purchased recently and the factory software is used, and the operating conditions were careful, then there is a high probability of a common defect, since even popular Xiaomi devices may have a flashing display due to a manufacturing error. Therefore, provide the seller with an appropriate guarantee confirming your purchase. It is also recommended to demand that the device be replaced with a new one and start counting the warranty period again, so that similar situations do not arise in the future and you do not have to constantly visit service centers;
- If water gets into the case or is unexpectedly dropped, the display matrix may be damaged. As a result, inactive areas may appear on the flashing screen that do not always respond to touches. Under such conditions, you must contact the service for help to install a new matrix;
- It should be noted that, due to an impact, the cable displaying the image becomes disconnected and does not create the required contact;
- Check the battery, as a defective battery may not provide enough power to operate a demanding screen correctly, which can be seen by almost imperceptible flickering, which can be annoying.
A flickering screen is one of the most problematic problems in terms of interaction with a smartphone. Therefore, identifying the real problem will help correct this defect and return the gadget to stable operation.
Secret codes for testing
There are several more ways to find a possible problem; to do this, refer to the service codes, which are suitable for all smartphones running Android. The codes can help in setting up the system and identifying the reasons when the smartphone screen begins to tremble (twitch) or shimmer with all the colors of the rainbow.
