Hi Folks, first post on here and new to tablets,so I'll try to be clear as possible. I received my 7015 yesterday, it powered up ok and I saw the battery indicator was yellow so I shut it down and charged for about 15 hours. Today after powering on tablet the screen is full of lines and jumping around crazy. When it clears up enough to see ,the battery indicator is still yellow and powers down after a few seconds. Did I get a dud out of the box or has anyone experienced this before? Adapter outputting 5.28v.
