When you find your phone display flickering, there are several reasons for this odd behavior. These include buggy software or loose internal connections that could make the display malfunction.
In order to resolve the problem and get your display back to its stable self again, try these fixes.
How to fix phone display flickering
Restart the phone
A reboot usually fixes any temporary software or technical hiccups that can cause the display to flicker. It also kills any processes and third party background services, while refreshing the components of your phone in case any crashed at some point.
To do this on Android, open Settings>System>Reset options> Erase all data. iOS users can also perform a hard reset on their devices by going to Settings>General>Reset>Erase all content and settings.
The process will take a few minutes depending on the amount of data in your phone.
Boot in Safe Mode
This works only for Android devices. Switch to Safe mode by doing this:
- Press and hold the power button
- Touch and hold Power off
- The phone will restart in safe mode and the phone display flickering will stop
Exit safe mode using the same steps but select Restart instead of Power off option.
Disable Auto brightness
This setting alters the screen’s illumination based on the light sensor data. A hardware defect or software update can also lead to phone display flickering, so you can disable the auto brightness option by doing this:
- For Android: Open Settings>Display
- For iOS: Settings>General>Accessibility tap Display Accommodations
Check your phone for updates
A messy software build can cause the phone’s display to flicker. Wait for any fixes, patches or updates from the manufacturer and then install them. Sometimes you can revert to older firmware depending on your device.
Disable Hardware Overlay
In order to render graphics, the CPU or GPU can be interchanged in your phone, but for older devices, the transition can be a struggle as it forms the composites. This causes minor delays between tasks so your screen will fluctuate and the display flickers.
To resolve this, set the phone to assign graphics to the GPU via Developer options under Disable HW Overlays. However, this consumes more power as GPU is meant for more intense apps.
If nothing works, get your phone checked by a professional.
