I think it seems certificate issue.

Please use samsung certificate when you build and execute your app on Samsung Wearable devices such as Galaxy Watch or Gear S3.

If it's not certificate issue, please give us detail information with error message.

 

 

 

I've followed the guide, and now the installation on visual studio stays stuck in "initialize debugger".... i've created the certificate (including the duid of my galaxy watch), set it as active, cleaned and recompiled the solution and retry to install...nothing to do

With the guide of your link, i can't install my app to my galaxy watch due to -12 error
