It is not a problem with neither your smartphone not the Android OS. On every modern Android with a brightness sensor when the screen is on low brightness, browsing causes the screen to flicker. If you do encounter this situation, quickly post on our forum to see if you can fix it yourself.
Why is the Android screen flickering issue arising?
They key reason for the flickering issue, is that the OS is not able to decide between hardware GPU or software CPU. The issue is more common when searching apps. This encountered a flickering issue when opening small apps and when browsing on the Chrome app or when using your phone’s screen.
How to fix Android screen flickering issue
If the issue of a flickering display arose after installing a bunch of apps or just out of nowhere, you can hold off the visit to the service center for now. Here’s our quick guide on what you can do to fix the Android screen flickering issue with ease.
Method 1: Boot the device in Safe Mode
A fail-safe feature built into the Android OS, safe mode enables you to go back to the stock Android device you got out of the box and test out any abnormalities that you’re facing. When the Android screen flickering issue pops up, you can put your device into safe mode, check to see if the issue still persists and then diagnose accordingly.
From the home screen of your Android device, press and hold the Power button until you see the power menu screen pop up.
On the menu screen, press and hold the Power button icon until you see the safe mode pop-up menu appear on the screen.
The screen will ask you to confirm if you wish to “Reboot to safe mode”, so go ahead and press the “OK” button to boot your Android device into safe mode.
Now that your Android device will boot into safe mode, all the third-party apps that you have installed on your device will be disabled and hidden.
This should leave you with only the stock apps, giving you the room to see if the Android screen flickering issue is app-related or connected to the hardware.
Method 2: Modifying the Developer options
Apart from all the awesome hidden features offered by Developer options, there are some options in the menu that can help you fix Android screen flickering. Developer options give you the ability to disable options such as Show surface updates and Disable HW overlays, which have been associated with Android screen flickering issue by several users.
If you don’t have Developer options enabled already, do so by heading over to Settings >About phone and tapping 7 times on “Build number”
The Developer options menu will be added to the bottom of the Settings app, so access it and scroll down to the Drawing
The first tab under the Drawing section should be Show surface updates, so simply press the toggle switch next to it if the option is already enabled.
Similarly, use the Developer options menu to find Hardware accelerated rendering section on the screen.
Under this section, you should be able to find the Disable HW overlays option on the screen.
Press the toggle switch right next to it to enable to option and set screen composting only to GPU.
Basically, the Android screen flickering issue occurs when the system hardware switches between the CPU and the GPU for displaying content on the screen. By toggling on the Disable HW overlays option, you can physically eliminate the Android screen flickering issue by putting the display operation under the GPU.
Method 3: Disabling Adaptive brightness on your device
The Automatic/Adaptive brightness option means that the brightness of screen changes according to the outside light. So when you cover your phone’s photometric sensors, the screen becomes dark and when they are uncovered, the screen becomes bright again.
Go to Settings > Display > Brightness
Find the option Automatic/Adaptive brightness and deselect it.
Since the screen flickering issue in relation to screen brightness is more transient that instant, this might not be the solution you're after. If none of the above methods work for you, you might need to consider the last resort.
Final resolution – Getting Android screen flickering issue checked out
If none of the methods above helped you get the Android screen flickering issue to be resolved, get your phone checked out at a service center. You may have a hardware issue, which means you’ll need to have the front glass panel or the entire display screen replaced.
Depending on your mobile device and how old it is, it might cost you a fair amount to have the hardware replaced. However, in some cases, it isn’t the screen that is damaged, but the proximity and brightness sensors, which still requires you to bring your phone into the customer service center, but might end up costing you a lot less.
If your device is out of warranty and you aren't afraid to experiment, you'll find a range of experts on the XDA Developers Forum that have a fix for you. However, these experimental processes need some amount of repairing knowledge and a bit of courage as well, so tread with caution.
