One common one is swiping up to go home from the camera on the lock screen and seeing your home screen wallpaper for a few frames. It's such an odd bug as it's really in your face and hard to miss, yet it hasn't been fixed, even on my Galaxy s21 ultra? Hopefully when one ui 4 comes up, samsung can stop focusing on the skin they put over top of android 12, and spend some quality time improving animations (which still are slow and on occasions entirely missing?) and better optimising the software. And adding a vertical app drawer, which I still don't understand why it isn't an option.
That does help, but the bug is still there even if its only for a couple frames. It's not that big of a deal, but it is just to show how Samsung really needs to work on optimising software. I would send a screen record but I can't go to the lockscreen while recording lol
