I have no experience with it but check out Samsung android watches
I would say they do almost all the functions of the Apple Watch.
My daughter-in-law the only android user has a Samsung watch as well. I would say it is the showcase of the android world as far as watches go.
There have been some other comments in here about the effectiveness of how you would use a watch as a communication device.
All I can say is millions of people do it and an incredible convenience for people who have hands on jobs where it’s not practical to hold the phone in your hand.
As far as Apple Watch, yes you can effectively communicate with it and I suspect Samsung watch would be the same.
Personally, I do not use the Apple Watch much to communicate. But wow, is it handy when you can’t miss a call and your phone is someplace else in the house or you were in the middle of something. Now that I think about it, I will pick up a call frequently or fairly frequently and then if it’s going to be a long conversation, I’ll seamlessly switch to my phone.
You can use voice text or the watch even actually has a tiny keyboard. When I use text from the watch. It’s only sometimes to acknowledge a message. I send a quick reply.
To answer your question, yes, my watch is very smart. As another pointed out, it also has built in GPS. It also does a lot more and I can’t emphasize the word a lot more than enough. It would take me a full page of a post in here to outline everything that it does.
