Hi. Just got my son a tablet for Christmas (2nd hand). Seems very nice and all, but can't seem to do anything on it and he is VERY disappointed! I don't actually even know the brand. Model # says generic. Firmware version 1.6. Build # WMT2.0_105. Somewhere I read that is fake and no good. What does that mean? What can I do? Basically it all looks fine except that it shows I'm connected to the internet, but won't open anything. Why is this? The other weird thing is is that we charge it and the battery runs out in no time at all. Any thoughts? Thanks so much!
