navigator.userAgentData not available in Samsung Internet


according to "client hint" | Can I use... Support tables for HTML5, CSS3, etc client hints should be available in the samsung browser but at the moment however I tried to access them I could not.

In Chrome they are only available on mobile in “https” context, not in “http”

However Samsung Internet browser v17(this is the one I have access to and I tested this on, seems to be the latest one) seems to not have navigator.userAgentData at all, no matter the context.

Can someone please confirm the behaviour and/or if this is a known bug?



I also encounter the same problem. My Samsung Internet is v17.0.7.34, on Android platform. The window.navigator.userAgentData returns undefined.
