Hi,friends of mine here, here is the thing: I just got this PIXI PIUS 2 months ago,it worked ok in the last 2 months. The tragedy happened yesterday morning when i waked up--the sreen not working anymore,though the keyboard works fine. The last night,i put my PIXI on the touch-stone as usual,but second day,the screen became like this. I seeked some info about this,says charging on the touch-stone will cause over-heating,is that so? Except change a new PIXI,any other idea?
