If your phone becomes excessively hot while charging or gaming, remove the protective case and allow it to cool.
4. Disable Adaptive Brightness
Adaptive Brightness occasionally causes constant brightness changes.
Settings → Display → Adaptive Brightness → Off
Restart the phone afterwards.5. Lower the Refresh Rate

7. Update All Apps
Some applications conflict with Android graphics rendering.

8. Boot into Safe Mode
Safe Mode disables third-party applications.
If flickering disappears, a recently installed app is responsible.
Remove apps such as:- Screen dimmers
- Blue light filters
- Custom launchers
- Gaming boosters
9. Free Up Storage Space
Low internal storage affects Android system performance.
Keep at least 15–20% storage free.

- Remove charging cable.
- Close heavy apps.
15. Reset Display Settings
If your phone offers display reset options, restore them to their default values.
16. Factory Reset
If software corruption is causing flickering, a factory reset may resolve the problem.

17. Inspect for Physical Damage
Check whether:
