I made the mistake of purchasing the k1 shield tablet and i lost soo much respect for nvidia. Any pressure on the screen causes color shift in the center. Picking up the tablet eith ur fingers on the bqck causes color shift. The back cover of the tablet is loose and the top and bottom and lifts up a little when you move ur hands. The new marshmallow update has been a joke. It deletes apps with no indication because of a bug and the cpu gets pegged at 100% and the battery lasts 2 hours with the screen off and gets burning hot. You can only charge it when the device is off. Its that bad. To make it worst, nvidia has not pulled the update and it affects every single shield tablet running marshmallow. Its been 3 months and no update has been pushed to fix it. All these problems are very very very comon on this device. Just going on the shield reddit and nvidia shield forums will prove that. To make matters worst, nvidias response seems to be pretending its not an issue at all. The first kindle fire was built soo muxh better im so disappointed. Sorry for the typos im on my cell.
