Weird thing. I get email notifications even when my Nexus 4 is completely powered down. It wakes me up at night. I have to power up, wait for the wifi to connect and then read the email. It's completely weird and I can't figure out how the device can receive emails and notify me without power or even a wifi connection. Seems like the 3G never shuts off maybe, even without power. Can someone help before I go nuts. -- Sleepless in Toronto
