Google Inc. has released the Android 6.0 Marshmallow mobile operating system for some of its Nexus devices this month. However, the new OS has yet to arrive on other branded mobile devices, such as Samsung's Galaxy S6, Galaxy S6 Edge, Galaxy S6 Edge+, Galaxy S5, Galaxy Note 5, Galaxy Note 4 and Galaxy Note Edge.

Since the American Google made the final code of Android 6.0 Marshmallow available, developers at the South Korean Samsung have been able to work on releasing their own OS updates, according to Android Geeks. The comparatively new Galaxy S6, Galaxy S6 Edge, Galaxy S6 Edge+ and Galaxy Note 5 will be among the first set of devices at the company to get Android 6.0 Marshmallow updates.

Because the Marshmallow OS is not vastly different from the Lollipop OS, Samsung is likely to be able to roll out its software updates this year. In fact, the company has already prepared the beta version of Android 6.0 Marshmallow for the Galaxy S6, PC-Tablet reported. It has not yet been put through its paces by the developers, but, after it has been tested, it will be made available to users.

Samsung Galaxy Note 4 users are also likely to receive Android 6.0 Marshmallow updates by the end of the year. However, there has been no indication about when Galaxy Note Edge users can antipate their OS updates.

Samsung's OS updates are likely to arrive with improvements in native applications and the user interface. The company's iteration of Android 6.0 Marshmallow is expected to bring improvements to the app-permission system, a new Doze mode for improving battery life, native support for finger scanning and an enhanced RAM manager.

Meanwhile, Android 6.0 Marshmallow updates for a variety of other Samsung devices are also believed to be in the works, Gizmo China reported.
