I have on one occasion had the screen seem like it went to one handed mode but I could not unlock my phone cause the fingerprint sensor would not read my finger. It also was not aligned correctly with the picture on screen. In addition I could not get in via pin cause the numbers would not match up where I pressed. The button layout was bigger than what thescreen showed. Reboot fixed the issue.
Today I tried opening the phone app and it kept wanting to go to split screen. I swiped away all open apps and then I was unable to select the phone app which is in my bottom bar. Reboot fixed this as well
Just had that happen this morning before work...made it very difficult to navigate.i was unable to find a cause or what was pressed and had to reboot the phone as well
