Samsung plans to offer the Android 6.0 Marshmallow update for its Galaxy S6 and Galaxy S6 Edge from 11 February.
Other Galaxy devices will soon follow.
Samsung said it will make separate announcements on details of its OS updates schedule for each market.
With Android 6.0, Samsung said it will roll out enhancements to the edge screen of the Galaxy S6 Edge.
Android 6.0 was first unveiled at Google I/O on 28 May 2015, and introduced a redesigned permission model with eight permission categories.
An opt-in system is now used which prompts users to grant or deny individual permissions to an application when they are needed.
Android 6.0 will also provide native support for fingerprint recognition, while a new power management scheme will reduce a device’s background activity.
Marshmallow also supports USB Type-C, including the ability to instruct devices to charge another device over USB.
