Is anyone else having this problem? When my Nexus 7 (32 GB) is in standby mode, it often won't wake up. It happens whether charging or on battery. To wake it up, i have to perform a soft reset by holding the power button down for over 10 seconds. It occurs about 75% of the wime. Usually it happens when it has been in standby for a while but sometimes it happens even when it has been in standby for only a few minutes. I've read that many people are having issues powering up when they have shut their tablet off, mine has never had that problem. It only occurs in standby. I'd hate to send it back for this because everything else about it seems fine. Any ideas?
