I don't think its just the she's i have a flip 4 and it started having screen issues after the update in sept. I had to start leaving the phone open or it would take an hour for the screen to be usable. It would get calls and messages, but the screen was blacked out. After this last update, it updated, I watched the screen it was lit the whole time, and when it booted back up the screen went dark, and its stuck on the login screen, which I physically have to put my pass code into to boot up.....and I cant. Its been a week and all I've been able to use it for is an alarm clock.... for preset alarms
