I have had the N7 since release and after my one year was up it started having problems of only being able to use half of the screen. it shows the bottom portion but will not let me use it, I was wandering if there was a way to edit any internal (rooted) settings that would made it where the screen would only use the top half and keep the bottom half black, kinda faking it to think the screen is smaller than it actually is. I have tried re-rooting the tablet to see if it was a software issue but it seams to not be. I can plug a mouse into it and it will let me use the bottom portion so I have deemed it as physical.
