I recently have the iphone 12 pro max and it is having a problem where its frozen on the lock screen on a tab and it wont let me power off my phone or get into any other apps. Iphone has been giving me so much problems and its getting ridiculous. I would expect a 12 pro max to be a good phone and better but clearly not. Trying these techniques are not helping me at all. I would like to know why this is happening.
