After announcing the Galaxy Beta program to test Android Nougat on Galaxy S7 and S7 edge, Samsung has set-up a new team to focus on software development for the former flagship Galaxy S6 series.

Samsung is working on Android Nougat-based firmware bearing build number: XXS5DPK7 for the 2015-based Galaxy S6 and S6 edge, SamMobile reported.

However, the final version of the software might change, as there are chances of bug creeping in to it and might require re-calibration of the source code to fix the issues. Going by the previous release pattern, Samsung Galaxy S6 and S6 edge are expected to receive the Nougat update after the current flagship Galaxy S7 series gets them.

Word on the street is that Samsung might roll-out the Nougat's public version to the 2016 models in January next year and release it later to the Galaxy S6 series before the end of first quarter of 2017.
