Sometimes the buttons and short cuts for the apps light up when touched but nothing happens. Sometimes some will work and other don't. The lock screen will just pop up. I'm using ADW. The location of the buttons on the screen isn't the problem on one page one will work on the next page same location different app won't. It doesn't seem to matter if it's connected to the computer or the hardwired charging system I put in but seems to happen more when I use that one. But once I disconnect it and restart the phone the problem continues. I pulled the battery and left it out for over 30 minutes also.
