Problem after upgrading my iPhone 5s to iOS11
Hello,
I have upgraded my iPhone 5s to iOS 11. It works fine for less than an hour then all of sudden it shows a white screen with Apple logo and stays at this screen. I still can hear some notification sound in my phone but the screen is stuck at this logo.
I tried hard restart ( hold on power/home buttons together ) but no luck.
Later, the screen starts to flash at the edges.
How can I solve this?
Best
