Why My Mobile Screen Light Is Blinking?

You might see a tiny, one-pixel-wide flashing light on your Galaxy smartphone if it has an Infinity display. The proximity sensor’s activation results in the illumination of this light. The proximity sensor is situated beneath the display panel in devices with Infinity displays, like as the S20, S10, and Note10 series, due to the reduced bezel and increased screen size. The proximity sensor was tucked away near the top of previous devices, beneath the bezel.

On your smartphone, a light may flash at the top of the screen when the proximity sensor is engaged. This is expected and normal.

How do I fix my Android screen from flickering?

There are a few solutions to the flickering Android screen because desperate times call for desperate tactics. You must first realize that phone screen flickering is primarily a software issue, so we start there. Visit the service center as a last resort if the issue is hardware-related.

Reboot your phone instantly

Rebooting your device is a quick repair for Android screen flickering, just like it is for any other issue you might encounter.

Disable Adaptive Brightness (Mobile Screen Light Is Blinking)

In 5 out of 10 cases, the adaptive brightness feature on your phone is to blame for your Android or tablet’s screen flashing on and off. Your screen’s brightness is adjusted in various lighting situations through adaptive brightness, commonly referred to as auto-brightness. However, occasionally it may result in the display flickering problem due to software problems.

The adaptive brightness toggle should be located in the notification shade on the right side of the brightness slider on the majority of Android phones. To turn off adaptive brightness, simply hit the ‘A’ button. To disable it instead on your phone, go to Settings > Display > Adaptive brightness.

Disable Surface updates and Hardware Overlays in Developer Settings

Using the CPU or GPU, your Android smartphone chooses how to display content.
