Ancient iPad Air 2 has begun typing by itself and opening apps by itself. Difficult to log in because it starts typing at the login screen, eventually causing enough errors to lock me out. If I do manage to log in various apps open by themselves. Browsers open infinite number of tabs until lockup. I've reset the iPad restoring it to it's factory only content and deeply cleaned the screen. Nothing has helped. Is it fixable or should I just forget it? I really like its light weight. Great for reading in bed. I have several othe iPads, including an original and a Series 10, all working fine. Of course the original is basically useless, but still boots up and connects to my network. Any ideas would be appreciated.
