There was a new jellybean update release 4.3 to most networks.
Its not with out its problems.
So be sure if your a S3, S4, Note 2 User the new features out way the potential issues around the internet listed.
Ive found one so far which has miffed me. My phone can no longer ping out due to a ICMP socket being blocked. Which as a net worker i use a few times a month.
* I have reset the phone, spending most of Christmas day getting it back up and running.
So my advice is to have a google about just to make sure you want to update. The 2 New main features that dont effect me are the group play, and support for the new gear watch.
Rant xda developers
Merry Christmas everyone
