I have an Android Tablet and I is fully charged but when I power it up it only shows me the ANDROID sign on the screen in stead of the home page coming up. What should I do? I order It from NOMORERACK.COM. I got it in the mail about 3 weeks ago. I got up with them and they said that I've had it over 7 days so there's nothing they can do. Please help. Thanks Brandy
