I'm having the same problem, i actually have2 aristos but it only does it in one off them. I'll open up the internet browser and it will work for a few minutes then crash. I open it again and it will crash right away. I then open up the camera and it crashes as soon as i try to take a picture or change a setting. It just does it randomly. If i open the browser again and not do anything it will work for 10 minutes the crash on its own. I have plenty of memory space and ram space. The crashing isn't logical.
