I recently bought this MID7042 tablet from Frys and settled on the unit I got on the second device exchange. The first had a problem with the screen and wifi (kept getting interruptions and buffering on netflix). The second would not stay connected to wifi unless I stood right next to the router and even then wifi would die after 10 mins or so. The third unit seems to be better by far though the screen is still a bit dim for my taste. I rooted the tablet (without flashing a custom rom) and installed gapps. All seems to work fine in this regard. However, I don't get email notifications (using standard email app) or alarms when the device is in sleep mode (screen off). The pending notifications all pop-up at the same time when I unlock the screen. On the good side, running apps seem to stay connected (Pandora, Tunein) when I turn the screen off by pressing the power button. But even these eventually die after some time. Anyone else experienced this behavior? Could it be a hardware issue? TIA.
