At only 10.17 MB, the update is quite small and so is the list of fixes:
Settings > About Gear >Update Gear software.
And that’s it, your battery drain headaches should be in the past! Unless you’re using the Gear Sport, in which case you’ll have to wait a bit more until an update is released for it as well.
The fix wasn’t the fastest one we’ve seen, but still, Samsung deserves credit for taking the issue seriously and providing people a proper solution.
