How to Fix Auto Brightness Not Working

A short step-by-step path for auto Brightness Not Working that checks overlays, heat, and display behavior first.

Quick answer

Remove screen overlays and cool the phone first, because heat and bad touch layers often look like bigger problems.

Common signs
Touches register lateSome parts of the screen feel unresponsiveHeat or screen layers make the problem worse
1

Remove overlays and test bare screen

Bad screen protectors, gloves mode, or floating apps can create false touch problems.

2

Cool the phone and restart

Heat can make touch response feel worse than the real underlying issue.

3

Test touch in one simple app

Use notes or settings to see whether the issue is system-wide or app-specific.

4

Update display-related settings

Refresh rate, gesture mode, or a pending update may be part of the problem.

5

Back up if the issue stays

Persistent dead zones can point to hardware, so save important data early.
