Samsung debuts Android 6.0 Marshmallow beta test in the UK and South Korea
Unfortunately, the Galaxy Care app is only available to Galaxy S6 and Galaxy S6 edge owners in the UK and those on KT and LGU+, two of the major carriers in South Korea. If you meet these requirements, you'll need to create a Samsung account and then download the Samsung Care app from the Samsung Apps store. Once the registration process is complete, the phone will start downloading a beta version of the Android 6.0 Marshmallow update.
The program has debuted yesterday and will last until January 18. This probably means that the first Samsung phones will start getting the Android 6.0 Marshmallow update - the official update, not one of these beta builds - not earlier than February.
