iPhone 4 impossible to reduce screen unless turn it off & on
After upgrade of iPhone-4 to iOS7 screen sometimes changes to magnified size especially happens when touched screen somehow during bell ringing.
It is never return to oprdinary mode by multiple gesture, two finger use or so, but turn off and on again. It make me difficult to answer the call or turn off as slide the button to unlock or turn off button is too big.
Please help what is the solution.
iPhone 4, iOS 7.1.1
