My phone has the locked symbol on the top.
I can't turn off the phone. It doesn't respond to any normal button commands. What do I need to do?
If a button or switch isn't working on your iPhone or iPad, here are a few steps that might fix the issue. If they don't, you'll need to set up a repair. Remove any protective films or cases that might block the button or switch. Check for debris or dirt around the button or switch and clean with a soft cloth.
