I am also facing this issue after OneUI 4.1 update.

Is it the exact same thing as the video I gave?

Reported by numerous users here, reddit, xda etc on mainly A52 models and S20 fe

So it's a common issue. Is it hardware or software? I tried a lot of things but no fix

[Gourav_Mistri]

Yes... Absolutely the same problem is happening with me.

[mashrukh]

Do you think it's software or hardware?

[Gourav_Mistri]

I think it's a software based problem and can be resolved by a software update.

Try and use on tap AoD with AoD's auto brightness on. See if the AoD goes to full brightness sometimes and then normalizes. If that happens then AoD app is the culprit (Which is an issue I face too).

Have you faced this issue and could you elaborate your answer?
