I only have 3 games on my Nextbook tablet. Hardly ever use it for anything else. I look up things on my phone. It stops and locks up after a few minutes of a game. Then goes to Powerup and reboot. I try playing again. It will let me play for about 10 minutes. Does it again. After a while, I put it down. Help, I'm sad I love playing games that's why I got it.
