I was wondering what would cause this and how I can avoid it? The only way I can fix it is to do a reset. Sometimes it happens at the most inconvenient times.
Might you accidentally be zooming by either spreading two fingers out or double tapping the screen?
Make sure you have zoom turned off: Settings>General>Accessibility.
I should have mentioned that this also happens on my "Slide to Unlock" screen as well as my home pages which are not zoomable.
Sounds like you should contact Apple to see if there's a hardware issue.
I just checkedthe Accessibility option and now see that it is possible to zoom any screen by double tapping with three fingers.
Thank you very much. It's nice to learn something new. It's a bit of an odd zoom in that you can't move the image around like you normally can when you zoom.
