I just received this tablet from a friend of mine since he was selling it for cheap. My wife was using a facebook app that was android. Now, it was doing a strobe light like effect and currently is not turning on the screen or anything of that sort. I am not sure what happened with it or how to fix it. So this is a two part question..... 1) What model of the tablet do I have since the box I received it in is just called a MID? 2) How do I fix this problem so I can use it again?
