Screen becomes unresponsive after iOS 12.4 update
I've upgraded to iOS 12.4 on my 5s today, and after the update the screen gets stripes and shades (on the pure blue&violet surfaces) and then it becomes unresponsive to everything (home & volume and power buttons work) that i have to lock the phone and keep it locked for a few seconds and then unlock it to make the screen function again. I had iOS 12.3.1 ipsw downloaded via iTunes and iOS 12.3.1 backup, so I tried to "downgrade" it thinking that it'll turn back to its previous state before the update but it didn't work either. Any comments?
iPhone 5s, iOS 12
