Hi Guy i have also buy this tablet from Sunsky from China. Surprise when i have try to make a hard reset for to have a Factory Setting it don't make this work. Why? I have contact the seller but they are so complcate, also o have send they a videi where i show hot the tablet failed this operation. I have ask they: If i want to resell this tablet how can i to erase all my account there? They suggest me to connect at the pc and link the tablet at the pc, now i format the memory and is done. Not true, is all the same. Why it don't make the Master Reset? They will asking at the engineers! I need to laught so much?
