This is a long shot, but if it were mine, I would do a complete reset to factory defaults and then test the device BEFORE I ADDED ANY APPS. Make sure the thing actually works, test the WiFi, surf the 'Net, test the camera (still and video), add some music (not too much, just a few songs) and make sure the songs will play. Plug in a set of ear buds and make sure both the right and left channels can be heard.
If the device isn't reliable with the factory defaults, then I'd pass.
If the device is reliable, then add your apps ONE AT A TIME and TEST, TEST, and TEST AGAIN before you add the next app. If you add an app and the device gets stupid, delete the app and test again. If the device is stable, then you just found a "bad app." This is a tedious process, but it works, trust me.....
