my 2 week old 8x died the other day. latest updates. was likely at about 30% battery, I took some pictures and left it to go to sleep. came back an hour later and it was totally black, no lights blinking. would not respond to any button. I charged it for about 10 mins and then pressing the power button for a long time turned it on again. perhaps the pictures I took drained the battery completely, I find that unlikely though..
