Lots of odd things started happening today, 1st problems in more than a year (and I seldom use it). Keyboard entries (Swype or Android) don't register in fields. Scrolling wallpaper stopped scrolling. Amazon App store real slow if not dead. Browser works (if you don't have to enter anything with a keyboard). Phone calls stopped working. Hate to factory reset, but looking likely. I'm rooted... can I reset rooted? Any suggestions before I go for that?
