Yesterday we heard that the Samsung Galaxy S4 would support the Galaxy Gear smart watch from next month, but it would appear that the Samsung Galaxy S4 already works with the Galaxy Gear.
The video below was out together by the guys over at Planete Galaxy, and you can see the Galaxy S4 connecting to the Galaxy Gear smart watch, and quite a few of the functions work.
Watch this video on YouTube.
So it looks like the basic functions work on the Galaxy Gear and the Samsung Galaxy S4 at the moment, the full functions will work when the software update is released next month.
