This is just to have this useful tip for my own use.
On my iPhone 13 the screen freezes from time to time. It’s not totally, totally inoperable. I was able to enter my PIN but not to be able to take an incoming call. But mainly just stuck on the screen of one app.
So what you do is:
- Press and release the up volume button
- Press and release the down volume button
- Hold the side button
- The screen turns black. Keep holding that side button!
- An Apple logo appears. Finally you can release the side button
You should now be good to go!
Why does this happen?
Wish I knew. If I ever find out I will document it here. At present I can just speculate that the phone runs out of memory.
