Having similar touch screen issue
I am having a similar issue to yours except It happens at random times during the day none of which are when it is charging, I have had the bionic for three days now and it had started happening the morning after I bought it, I charged it the night before using the charging dock that comes with the extra battery. Most of the time what happens is the notification bar at the top will start to pull down on its own and the screen will be unresponsive to any touching. I had the same issue with my previous droid which was the original but that was much more extreme as it would go to webpages, download files, make calls, store contacts, and even send texts all on its own. Never saw anything like it that is why I ended up buying a new phone and now im scared the same thing is happening. Is this a common problem droids?
