LB1120 new firmware released this week

I upgraded a few days ago after I got the notification (LB1121 i think, but essentially the same), and have had several issues although I can't say it's 100% due to the update.  So far I've had it switch from LTE to 3G (and not back to 3G until rebooting), have had it lock on to a different tower with poor signal (even though i use external directional antennas), and this morning I had reset it again when none of my devices could connect to the internet.  Pre-update, I rarely had any issues over several months.  The 3G and bad tower lock have happened before but extremely rare, so maye there was some tower maintenance in progress.  Bottom line is I see no benefit after the update, only possible issues, so I would avoid it.  I don't see any release notes to know what it fixes.  Hopefully I can revert back.
