Maybe I'm missing something here and if so I'm sorry in advance. Is there a way to have your messages synced with your phone like on the apple watch?
Using the stock messaging app will allow you to access history from your phone, but not on the standalone version as SMS is NOT a cloud service, and Samsung's messaging app, unlike Google's, which isn't supported on the Galaxy Watch, doesn't support cloud sync.
I'm using Google messages. Mine sync.
Nope, they don't. You can see unread messages on the notification (like any other app). Try to see the WHOLE conversation, however, and that's where you will find yourself stumped. In WearOS only the stock Samsung messaging app has this ability. WearOS, on the other hand, is different and does have other apps, including Google's Messages, that sync the whole thing.
Yes, I can read the whole message. And it does sync.
My point is that I do not use the stock messaging app on my phone. And even though I don't use it, the texts are still synced to my watch.
