the seller told me that they sent to the factory for repair.
if they tell me something about the model, I will tell the truth, which is that I received this tablet and no other, I asked them, and they did not answer me.
for me it was, and it is, a great problem, because I had bought a case and a keyboard for X16, now I have, but I can not use.
and now, I also have a X2 keyboard, and if they tell me this can not been, I reclaim.
although I admit that if they refund me 100%, I would not mind
