I got a large update this morning, download and installation went smooth just a very long process this time with a lot of changes. Seems to be running fine any problems I will advise.
Google it.. There's a few articles published but they don't really say much more than the upgrade notice.
I noticed though that I can now reorder the watch faces again in the app (wasn't mentioned in the notes). That went away just after I got the watch at release but looks like it's back.
I got the update on a UK version of the watch (no LTE). No internet, no theater mode widget. Update took nearly an hour and all this version got was some auto calibrate for the altitude thing (that still can't count floors). I don't know why Samsung keep holding back stuff for some regions, they're the same with their phone themes.
Mine is non LTE. Just realized I must of put this widget on the watch from the Galaxy app store when I bought the way home in January.
Search for theater mode on the Galaxy store.
