Across the pond in the United Kingdom, Samsung is looking for volunteers to beta test a Marshmallow update for the Galaxy S6 and Galaxy S6 Edge, meaning folks here in the US must be getting awfully close to seeing the update themselves.
Entering the beta seems easy enough, as all that is required is an unlocked model of the aforementioned devices. If you have that, all must do is sign-up for a Samsung account, install the Galaxy Care application from the Samsung Galaxy Apps app, and then complete the Galaxy Beta Program registration process.
We have yet to see exactly what Marshmallow includes for Samsung devices, but of course, there should be Doze, Now on Tap, and other various additions Google baked into Android 6.0.
Fingers crossed that once the beta goes smoothly in the UK, folks here in the US can get their hands on Marshmallow soon after.
