My iPad Air is on iOS 8.4 & freezes
since updating to iOS 8.4 my iPad freezes & when using keyboard to type it can be sensitive & adds extra letters I never typed & also if it can freeze too. I've deleted most apps & have pressed at the same time the home button & on button hoping to reset it but I still have freezing problems. What can I do to stop this so that I can use my iPad Air without any probs. I only had these problems since I updated to the iOS 8.4, before that it was fine . Help please! Thank you.
