My new iPad seems to have gone completely mad! At least 3-4 times a day while using an app such as safari, mail, setting, games etc. it seems to freeze but then the screen starts jumping around, zooming in and out, copying text, opening and closing the keyboard, while this is going on it is unresponsive to touch. Clicking the home button seems to stop this but as soon as it goes to the home screen it starts stuttering again with the screen shifting to the right then left until it opens the search screen and keyboard whereupon it freezes again.Resetting works for a while as does restoring, but then back to the crazy behaviour.Yesterday i reached the end of my tether when while on settings it actually set up a lock code all by itself and I couldn't stop it. Restored with great difficulty once again. Many times this happens when I wake it from sleep and more or less 5 minutes into using an app. Any ideas anyone ? Has this happened to somebody else? Would also add that using , say a google search or typing in words, after the stuttering/ freezing has happened , if I tap the 'u' or 'n' once they come out as double letters.
