Quite often people complain that the display itself starts to flicker. And the flicker can be very different.

- Damage to the screen.
- Problems with battery operation.
- Software failure.
- Problem with the video controller.
When the screen flickers, it’s difficult for a person to concentrate on watching content. This type of flickering is particularly annoying when the display is deprived of backlighting for a fraction of a second.
In turn, the variant when the display flickers without turning off the backlight is the most harmful. In this case, people’s eyes begin to get tired quickly – the feeling of “sand” in the eyes, next is a strong headache.

What should you do if the reason is faulty battery
Quite often users dismiss all causes except mechanical damage to the gadget. In reality, flickering or streaking can appear due to a weak battery. The problem is associated with a loss of power, especially when the battery has been in use for several years.
This option can be easily checked. It’s enough to connect the gadget to the charger and look at the screen while charging. If all image problems are gone, then the cause is related to battery power.
The way out is to use a different battery. Insert the new battery into the gadget and check if the screen flickers. It’s advisable to buy the battery from specialized stores and check its originality.
If your device has a non-removable battery, you can only buy a new device.
What about software failure
First, users are advised to check what brightness level is set on the device. If you are using automatic brightness mode, the gadget will constantly adjust it.
The screen will dim every 2 to 4 seconds. If you have a constantly decreasing or increasing brightness, then set the necessary parameter in the settings.
If the screen functions normally in quiet mode, but when you start tapping on it, the device lights up in different colors, check some of the options. It’s likely that the functions that show have been activated:
- Screen update.
- Window update.
- Hardware updates.
In order to fix this:
- Select “Settings” on your phone.
- Press “Additional Settings.”
- At the bottom, find the “Developer options” tab.
- Find the “Drawing” section.
- Press “Show surface updates”.
- In the window that appears disable all of the above functions.
The phone may also flicker due to hidden software glitches, OS clogging, and virus activity. The user is recommended to clean the phone, and roll it back to the factory settings.
Problem with the video controller
The graphics subsystem provides the picture output to the screen of the gadget. It consists of the processor, memory, and “wrapping”. If any element on the chip is broken, then the screen appears with stripes, flickering, interference, and other problems.
In this situation, it’s also not recommended to do the repair yourself. Only professionals are able to repair the screen and not damage the video controller.
To summarize, it’s quite difficult to detect screen malfunction. The cause is not only severe mechanical damage and partial failure of the software but also problems with the battery or battery charger. The battery loses power over time and causes unpleasant consequences in the form of flickering or “flickering” displays.
The only true solution, in this case, will visit the service center, where with the help of special equipment will hold a complete diagnosis of the device and identify the root cause of the failure. And most likely, you will replace the screen module with a new complete set.
