I've been using my ticwatch 2 (2016) scarcely with all its settings turned on. I like it as a watch by it self, what really bothers me is every time the watch goes down to zero percent power and is charged back. It wont update time until and unless my smartphone is reconnected to it.
The watch has built in wifi, it can install complete apps from mobvoi store, but cant update the time simply from the internet !
Its plain stupid
