My iPhone is suddenly in a weird mode where I can’t really use it. To get into it I touch one of the buttons which brings up the lock screen, but swiping the thing at the bottom to open it instead draws a box around that thing. Holding down the top button to turn the phone off gives me a slider I’m supposed to swipe to confirm turning it off, but doing that just draws a box around the slider instead.
After some experimenting I discovered I can double tap anything with a box around it and get the effect of sliding it, but then other stuff is weird, and mostly I keep getting boxes around the different control elements in each screen. I can’t get it to do anything useful.
What is this and, more importantly, how do I fix it? Or has it died a weird death? It’s a 4S with the latest or next to latest OS. I don’t know what started this, it was a few hours ago.
Thanks!
