The Galaxy Watch 4 with WearOS 3 still does not have the gesture based navigation that was present in previous WearOS versions.
I was extremely disappointed to find that the wrist based gesture navigation has been completely removed which was in the previous versions of WearOS. Well, there is only the option, to answer and reject calls and launch an app but this is only a small part of the functionality missing.
This is a super useful feature which is very hard to live without once you have used it, and was a big reason for myself going back to WearOS! It allows for one hand navigation which few smart watches can do. I am sure many people would be extremely grateful if it could be re-established.
For reference here's how it worked before:
This is a massive step back in functionality and usability of WearOS.
The Samsung settings are in no shape or form a replacement for previous WearOS gesture navigation.
There is no way to navigate notifications hands free, there is no way to return to the home screen hands free, the actual useful gestures are not there.
Beside, Samsung's implementation of quick launch is a joke. Previously it was a simple and natural shake movement to return to the home screen.
