Okay I'm so tired of this screen issue with my galaxy zflip4, ive only seen one similar report with nothing helpful. All of a sudden when I fold the phone just a little bit it starts lagging like crazily and then if you expand it back out it will either stop or persist. sometimes it stops after refolding it all the way and then opening it back up but other times it takes hours for it to stop even after restarting the device, folding it and opening it back up, clearing the cache, updating it, etc. im so sick of this issue and I don't wannna pay hundreds just to get it looked at. another thing is when expanding it back out during the lagging you'll often see a horizontal white bar appear quickly anywhere on the screen and then disappear. please give any advice because ive found no resolve for this issue.
