I got a Galaxy A52 (4G with Snapdragon and 6GB of RAM). Everytime there's a lot of black on the screen, for example when using the Always On Display or showing a fully black picture the black pixels show with a grey glow.
It looks like the amoled display doesn't turn off the black pixels like it should. This only happens when the phone is not on maximum brightness, and it gets worse the lower the screen brightness is.
This doesn't happen on my A51 (4G with Exynos and 4GB of RAM). I've seen a lot of other A52 and even S21FE users complain about the same problem, for some S21FE users changing the refresh rate to 60hz fixed the problem, but for me it's exactly the same in 60hz and 90hz.
Example: If i turn on the AOD at full brightness, everything is normal. The screen is black, the clock displays normally in white. - If i turn on the AOD at lowest brightness, the screen has a really intense grey glow everywhere, but the clock still displays normally.
