A friend sent me her old nextbook 3 today. I started playing with it and went to the app store that comes with the tablet to download angry birds. Afterward I got this message: Sorry! The process android.process.acore has stopped unexpectedly. Please try again. Below that it says force close. However, when I click it the message returns. I tried shutting it down and resetting with the button in the back with no change. Has anyone had this problem and if so, how did you fix it?
