Recently, I have been having issues with my tablet restarting automatically and I have no clue of what's causing it. I'm also noticing the screen is displaying a bit of choppiness or hiccuping. Is there some caches I need to clear or something? I know my phone (Nexus One) does this every now and then and I reboot into the system and clear some caches, anybody have any advice on what to do? Thanks in advance.
