What if you cracked your glass display cover can you fix it and how do you know if you cracked you LCD also?

The bluetooth could be a way of tracking people or something i think someone is controlling my IPT because it will close out to the home screen in the middle of a game and that makes me mad anybody know why it does that and if it can be fixed?

My IPT did not come with a polishing cloth doese every IPT come with one?
