Hi! I recently purchased a Samsung Galaxy A55, and now Iām encountering an issue with black lines appearing as an animation after unlocking my phone. This happens quite frequently, and despite updating the software and disabling the transition effect during unlocking, it still bothers me.
I tried lowering the refresh rate to 60, but Iām still seeing black lines after unlocking. And it is more obvious if I use light background wallpaper.
Overheating screen burnout, impact, dropping your phone can cause lines on the screen. You can restart your phone and see if the lines disappear. You can also reflash your phone with latest Samsung firmware, thus will tell you if it's a firmware or hardware issue.
