Lately, my phone has sometimes displayed a home page with only the top and bottom icons. When this happens, I can drag down and see the notifications as usual, but touching one of them does nothing. This happens up to 4-5 times per day. I have to power off/on the phone. Any ideas?
Does this happen in Safe Mode?
If not, this is being caused by an app you installed.
