AnonD-405901, 17 Jan 2017Thanks I bought it anyway & it's awesome! How can you customise?Open the Samsung Gear app on your phone and then go to Settings and Quick Messages. Unfortunately it doesn't seem to work with all apps, I'm not sure if it's a bug or if it's supposed to be that way. The ones for rejecting calls appear, but the message responses don't, at least not for WhatsApp (haven't tried SMS, maybe there it would appear).
I agree, it really is a great device.
AnonD-405901, 22 Dec 2016Does it show notifications from 3rd party apps?Yes, it does. You can even respond to messages (SMS, WhatsApp, BBM, etc.) with predefined (also customizable) responses.
