I just got one for my son and his has some crazy touch issue. On mine craft it's like you push on multiple places on the screen at once. Downloaded a multi touch test application and it shows that periodically there are more touches registering than what you are actually touching. I was planning to use this to root but may have to return it! Did some research and seems to be a common problem!https://youtu.be/5FaLm4qrDkA it seems like the problem exist only while on charge.
