Android 6.0 Marshmallow began its rollout over five months ago - but so far, just 2.3% of active devices are running the new version of the OS. Its availability on one more handset on one carrier in one market isn't going to make a huge difference to that percentage, but it will no doubt still be welcomed by owners of that device.
The handset in question is Samsung's Galaxy S6, which is now receiving the latest Android 6.0.1 release on Sprint. It's not yet clear if the update is also available for Sprint's Galaxy S6 edge, but if not, it probably won't be too long before it arrives.
The update bumps the Galaxy S6 up to build number G920PVPU3CPB6, and weighs in at 1235.87MB.
Along with the improvements that the stock Marshmallow update brings, Samsung has also added its own TouchWiz interface, along with other small tweaks including a new 'vibration pattern' when you receive calls and text messages.
While Marshmallow slowly continues to trickle out to more devices, Google has already launched a Developer Preview of the next Android version, known as the 'N' release.
