I have noticed that every so often, the touchscreen on my phone will go a little crazy. For instance, on the keyboard, it will randomly start typing "vvvvcvccvvbbvbbvvccv" and so on and so forth. It is that general area of the screen. Eventually it will stop, but the 4 main buttons on the bottom will become unresponsive. Then I lock my phone and then unlock it and it works fine for a bit, but starts going crazy again. Any thoughts? Note: I originally thought it was because of my Zagg, but after taking it off, it still goes crazy. So it can't be my screen protector doing it.
