Why does my iphone 4 zoom into the lock screen?

Sometimes when i take my iPhone out of my pocket it is zoomed in to the lock screen and i have to restart my phone because it won't let me un zoom it. Why does this happen?

You somehow accidentally enabled the zoom function. You double tap with 3 fingers to enable it on or off.

To turn off
Settings > General >Accessibility > Zoom

  • Why does my iphone 4S hangs up calls if I lock the screen? I have noticed my iphone 4s hangs up calls if screen is locked and the thing is it does it pretty randomly. So sometimes it hangs up while other times it won't. Today I made a call and locked the screen and nothing happened so the call was maintained but a few minutes ago, I received a call but locking the screen ended the call. So I called the person back and tried again, the call was ended again. Does anyone know what the problem is? Any help is appreciated.

  • What Zoom is best for my iPhone 5? I'm going to a music concert next week so i decided to buy myself a extra zoom for my iPhone 5 on ebay so my pictures will be able to see closer and be more clear instead of buying a camera, but as i have come to buy the zoom it has gave me 2 options, Aluminum Zoom and Optical Zoom. What is the difference and what one would be most suited for me? Hope you can help, thank you!
