Hi, Ive had the nexus7 for about a week and love it so far. It runs so smoothly. However... about 15 minutes ago while playing a game it suddenly crashed. I got a purple screen, with a black bar, then darkness. I have played this game a fair bit and although it is graphics intensive, there has been no problem whatsoever til now. I was not able to turn the machine back on with the power button as usual. It has now finally decided to switch back on but its left me a bit worried. I have a ridiculously unfortunate history with dud hardware and I wouldnt be surprised if I have an abnormal issue. Is it likely to just be overheating or should I be more concerned/Return it? Im particuarly eager to hear your advice as I was considering getting the nexus4 aswell when available. The game was dead trigger if that helps. Please let me know what you think I should do. Cheers in advance
