Samsung shows off One UI Watch for Wear OS
As it does with its smartphones, Samsung will be putting a skin on top of the new Wear OS platform that it is co-developing with Google. This new One UI Watch for Wear OS aims to "make the Galaxy Watch and smartphone experience more deeply connected" and to create "an entirely new Galaxy Watch experience."
Some of the things we can expect from the One UI Watch experience include auto-install of compatible apps from your phone to the watch, different clocks for various cities will be ported to your wrist, and numbers you block on your Galaxy Watch will be blocked on your phone.
