iPhone 6s Plus is unresponsive after 12 update
2 issues:
screen becomes unresponsive, and it does random actions later...
top of the screen flickers too
both issues happens almost all the time, so it is not possible to work with this phone.
My actions:
I had iOS 12.1.4 (I think) and I decided to update to 12.2 Today, I was hoping you realize and fixed this issue, and everything become worst (same issue even without any third party app installed on the phone).
IMPORTANT: Please I can't live without my iPhone for weeks or even days until it is fixed.
I have tried to come back to iOS 11 until you sorted it out but it looks like it is not possible officially, so I really need an official & supported apple way to come back to my previous iOS asap (I don't have full backup).
A quick reply will be appreciated, please I live and work with my phone.
Thanks, Christian.
