Samsung has been hunting down beta testers (which should not be too hard, really, for the rather juicy task at hand) to give its latest Android 6.0 Marshmallow update a try, targeting a slew of markets in the process with the likes of South Korea, the UK, and the US in mind. Should a user be selected, then he or she would be able to perform an installation of the beta version of Android 6.0 Marshmallow (which powers 1.2% of Android devices) on select Samsung Galaxy S6 handsets. Apart from that, it looks as though Samsung is preparing the Android 6.0 Marshmallow update for the Galaxy Note5 as well, since a group of users over in the US have also started to receive the test build.
Approximately 200 folks who are rocking to the AT&T network with their Galaxy Note5 phablets have already been selected, and should they have carefully followed the given instructions, then the update is ready and waiting in the wings to be installed. It seems that this particular Android 6.0 Marshmallow firmware is similar to the one found on the Galaxy S6 range, and will also feature the most recent security improvements for an added peace of mind.
You would do well to make use of a Wi-Fi connection to download the latest beta firmware update, as it is approximately 1.36GB in size with a build date of February 2. Galaxy Note5 owners from AT&T (in particular, the SM-N920A model) would be the most likely “target”, assuming one has already signed up for beta updates earlier on.
