As the title says, I found a Samsung watch Galaxy Gear S. It is unlocked and I can use it. How can I find something (e.g. email address) to contact the owner? I have no idea how to use this thing.
Agreed. I can't access any of the user contact data (e.g. email) since it is out of bluetooth range from the owner's cell phone. It seems like a trivial addition to add such a thing. I'll probably resort to posting in the lost and found section of the local craigslist/kijiji.
I have a gear S also. If the owners phone is turned on it should go into call forwarding. There will be an icon in the upper left hand corner.
Swipe upwards from the clock screen and choose contacts. I would try calling one of his contacts and see if they could maybe help you.
