I have a cheap chinese tablet i bought for my girlfriend awhile back. When she was playing her bingo games on it, she want to go chase after our son & when she came back to it it was back to the start screen. She looked and saw that there was 0.00 internal memory and all the apps were missing. You can install apps and do all the password things for the wifi etc... but when you power it down and start it up again its back to the factory settings... No apps, passwords etc... I read somewhere that everything is still in there, just theres something missing in the prog, thats causing it to have issues. Any clues????
