Despite having Android 5.0 Lollipop running on flagships withing a month of official release in 2015, Samsung has truly delayed Android 6.0.1 Marshmallow for it’s current lineup. Nonetheless, after multiple beta programs, Korean users have finally started receiving official Android 6.0.1 Marshmallow on Galaxy S6 and Galaxy S6 Edge. These builds are only for the G920S and G925S variants which means you can’t just download and install 6.0.1 Marshmallow on any S6 or S6 Edge manually. Hopefully, the update program will soon reach to a wider market. When that happens, we will have firmware tutorial guides up for each variant so that you don’t have to suffer another waiting time associated with regional differences.
Android 6.0.1 Marshmallow has native fingerprint support, Doze integration for better battery life and bug fixes which appeared in previous Lollipop releases. All of these features are included in Samsung’s new firmwares alongside some new TouchWiz additions as well. Support for different icon styles, new Edge functionality and even revamped Samsung apps are what you get with this official release. Right now, Korean users can get the new update from Samsung KIES and OTA(Over-the-air) update system. Carrier locked phones are getting there share of Marshmallow firmwares as well but there might be some delay.
