The research if been doing the digitizer in the touchscreen could be going bad or the control unit which I believe is attached to the back of the touchscreen but not for sure. Yesterday on my way home from work I didn’t touch the screen at all and kept it on the home page and only Bluetooth connected. It barely twitched for a few minutes after driving thirty minutes like it was going to change pages but it never did. I want to try and check the touchscreen connections this weekend. The one thing I don’t understand is why mine acted up a month and half ago for a week then worked perfectly fine until last week.
