Nexus 7 LTE 2013 receives surprise Android 4.3.1 update

The Nexus 7 LTE 2013 is receiving a surprise update bringing it to  Android 4.3 .1. It’s most likely an update with bug-fixes and patches, however Google had updated the non LTE version a few times with bug-fixes and had not changed the version number, so this is a bit odd. There might be more to this update than we currently know.
The update is OTA obviously, so if you haven’t received it yet, you will soon. Be patient!
