On my Samsung Galaxy watch, if I get a notification from my Unifi security cameras, for example, I get a little thumbnail image appear on my watch. There's no special app on my watch, just the app on my paired Galaxy phone.
Will it do this? Or would I just get a text notification? I don't understand smart watches well enough to know how much they are doing themselves vs how much of what they do is to be a mindless projection of whatever the paired phone tells them to do.
