If it's the unlocked version, there should be a banner on samsung members app to register. If its tied to a carrier I believe sprint and tmobile are the only 2 U.S carriers doing the beta I believe. Any other carriers were out of luck till a stable release (I'm on att)
I'm on the Beta program and just did the most recent update and suddenly I no longer have the Android 10 gesture navigation. I had been using it up until this most recent update and now under the navigation bar settings where it showed "More Options," it's greyed out and no longer allowing me to change back to the Android 10 gestures. Anyone know how to fix this?
