Hi,
Glad to be a part of the community of Androids!!!  I have an SM-V700 Samsung Gear.  Actually two of them.  Ummm, I'm getting ahead of myself.
Bought the watch from LETGO.  Good working condition.  Owner said the watch works fine.  Booted up and synced to my S6 edge +. 
All the apps on the watch work, except S-Voice.  Deleted and reinstalled the GEAR app 4 times!  Then factory reset the watch...nothing...
So, I take it to Best Buy, to the Samsung specialists.  The worked on it for 2 hours.  Then ended saying..'There's something wrong with your watch'.  Ok....
So I get lucky and find another Samsung Gear 1!  This time I ask the guy to show me that s vice worked....on his Note 5, it worked.
I couldn't get it to work on my edge plus again.  Called Samsung, they said it's compatible with my phone.  Took it to the Samsung phone techs.  Again, they said it was the watch!!! No way!!   Someone please a little help here!!!  Thanks in advance!
