Hello there, I have a coby mid7022...my problem is: Due a hit, half of my screen dont work, I mean, the touch..I can see all the screen perfectly but I can Touch in anything. I tryied factory reset and nothing works to me. Should I open the device and remove the battery? Cause I belive that here in Brazil there is not any coby support..what should I do?? Thx for the help.. sorry about the english.
