Google originally released its first Android 'M' preview last May, before formally announcing the launch of Android 6.0 Marshmallow at the end of September. But until this past weekend - almost four months after Marshmallow began rolling out to other phones and tablets - Samsung hadn't released the upgrade to a single one of its Android devices.
Indeed, the closest it had come to doing so was launching a limited beta test in South Korea and the United Kingdom, which began in December. But at long last, as SamMobile reports, Samsung has finally begun its Marshmallow rollout.
Android 6.0.1 is now making its way to the Galaxy S6 and Galaxy S6 edge - but so far, it's only available for those handsets in South Korea.
Unfortunately, the company hasn't yet announced when it will release the update for other devices in its range, or in other markets - but now that the process has begun, availability will no doubt expand to other parts of the world in the coming days and weeks.
Samsung is the world's largest manufacturer of Android devices by some margin, but its notoriously tardy approach to updating its devices recently landed it in hot water in Europe. A leading Dutch consumer advocacy group filed a lawsuit against Samsung last month, citing the company's "poor software update policy for Android smartphones", and claiming that it is "therefore guilty of unfair trade practices".
