I refers to the after-sales return, they detect a software error and update service, I now get my tablet, I deliver my apps and the problem comes back, I want to say that this problem also occurs when we reset the tablet, so the apps are not in question. I go to the store and I had the idea to make a video of the bug that the seller may well see this problem, it will again return. A week later, back of the tablet, an update was made again and changed some elements, I do not have a description. But after an hour, the problem comes back again, I return to the store and they gave me a standard exchange, but the same problem occurs again on the new tablet (less frequent, but it is reproduced)
I think the update is the cause of this problem. Sorry for my english, I'm french.
