Samsung is yet to officially announce an official roadmap for the update of their handset firmware to Android 6.0 Marshmallow, but it seems like Samsung U.K. is ready to give select Samsung Galaxy S6 users a sneak preview into the latest firmware version for Samsung handsets.

The announcement came from the Samsung office based in the U.K. via a Twitter post last December 22, where the company invited Galaxy S6 users to test the Android 6.0 Marshmallow beta. The photo shows an image of a Samsung Galaxy S6 Edge which connotes that the beta test is available for the Edge variant as well.

The post indicates that those who want to get the beta test must follow three simple steps: First, create a Samsung account on the company's membership site; second, download Galaxy Care from the Google Play Store; and lastly, complete the "Galaxy Beta Program" registration process.

Sam Mobile has posted a video showing the beta version of the Android Marshmallow on the Samsung Galaxy S6 handset. The updated mobile operating system modified for Samsung appears to have a new TouchWiz with a cleaner look, a few interactive animations and transitions, a "pro mode" in camera that allows more settings customisation, Now on Tap and many more.

The Samsung Galaxy S6 packs a 5.1-inch display with Super AMOLED capacitive touchscreen and 1440 x 2560 pixel resolution. Powered by Exynos 7420 and 3 GB of RAM. The handset's back-side camera is a 16-megapixel shooter with OIS, autofocus, LED flash, geo-tagging, touch focus, face detection, Auto HDR, panorama, and the front-side shooter carries 5 megapixels.

Android 6.0 Marshmallow continues to roll-out to third-party OEM smartphones and devices bringing new features such as Doze mode, which gives better battery life through smarter standby, upgraded fingerprint scanner settings and access to Android Pay. Only a few handsets now run on the new Android firmware, but some OEMs like Samsung are starting to catch up.
