Bought the new nexus 2013 and has absolutely no problems so far except for the fact that when my tablet is flat on the table my screen tends to not work at times but i'm always holding my tablet so it doesn't bother me too much. I recently just noticed however that i'm not getting a notification that anything has happened to my tablet. The notification shows up in the notification bar but i don't here my tablet going off alerting me or my LED light showing that somethings there. I made sure everything is turned on, notification sound and led pulsing. nothing changes. Running stock everything here on 4.3. Anyone else having this problem? Think its a bug in 4.3? i've passed my return day limit so i don't think returning at this point is an option.
