Increase Brightness

For the first time when I encountered screen flickering on my device, I tried to adjust the brightness and observed that on full brightness screen flickering stops, while turning down the brightness to lowest, the screen starts sparkling. Try increasing the brightness and see if that happens on your device too or not.

Check for Damage
