I'm have problems with my tablet. It's just a basic Nextbook tablet. The problems started a few days ago when all of my apps loaded and preloaded were "stopping". It gave the alerts of all of apps stopping. I turned it on and off several times and I never technically fixed the problem. I planned to restore/reset it. I turned my tablet off and back on again and it somehow manged to reset all by itself. I figured that the issue was solved so I set it up again. I tried updating the preloaded apps but it's not working they won't download and it's the same with apps I tried to download. The main problem is that when I now turn off the tablet, it resets itself again when I turn it on! What do I do?
