Is there a setting or program out there that can lock the screen and buttons on the phone so that the screen light doesn't turn on until you press the lock button to unlock. I don't use the holster for my phone as i get a white screen of death when i use it, I simply lock it and put in my pocket. The problem is that when the screen or buttons on the side are pushed by accident (which is very frequently), the screen turns on. As a result my battery is running down very quickly. Any ideas?
