Every app crashes, says 'not responding'
I just received this tablet, it was used but I factory reset it before using it. I can't run any app I've downloaded, they run extremely slow for about 2 minutes then say 'soandso app is not responding' and closes. The person I got it from said they had the same issue. I've tried everything I can think of and nothing has fixed it. Please help!
Is this a good question?
