I don't understand how no one is having problems with the K1. I had it for a week and could not get rid of the pink green lines going across the screen. I tried everything. It was just for my craft, no other apps except the GO app. I had the wifi off and air plane mode on. It glitched especially when I took pictures or switched it from jpeg to video.
I thought it was something wrong with it so I pulled out the note 4 and same glitches. When I pull out the ipad
mini 2 I did not have 1 problem. I tested all 3 back to back.
After reading all the positive post here I'm bummed I returned it. It is a nice table . Glad everyone is having better luck than I did.
