recently, my Nexus has been dropping- and not regaining- data through the night. the phone is left bedside, on a charger and when i wake up, i have no data. this is independent of me CONSTANTLY losing LTE connectivity. i thought that the backup assistant may have caused it, so i deleted that due to the backup happening around 2am nightly. nothing changed. i tried turning on airplane mode.. and then turning it off to jumpstart the data with no luck. the only fix is rebooting the device... every morning. any ideas?
