Top half of my S21 5g randomly dims, not completely blacked out , but at least dark enough to be a nuisance. Returns soon after, locking the screen or going to home page.
 Is this a fault or some kind of auto battery saving setting?
This started from day one. This never happened on my previous device, S10.

yes but why does only the top half dim?
I will try it without auto brightness on👍🏻

not sure about the top half dimming. I also have the s21 and I haven't seemed to have that problem. Still I think maybe try turning of auto-brightness?

I managed to catch a screen shot..
Am I missing something or is this normal?
I used Google search to get to this page. could this be a factor?
I don't want to send my phone of to Samsung as in the past it has taken 3 weeks to return!

does it do it just in Google? might be a software bug that requires factory reset

I'm going to try and replicate it using Google search widget, Chrome app and then Samsung's Internet app, in that order and hopefully see where and when it happens.

That is definitely a defect, no doubt about it. This is not normal behaviour of automatic brightness or any display function for that matter. Contact Samsung and get your phone replaced is my suggestion.
