Samsung is now developing the Android 7.0 Nougat update for the Galaxy S6 and Galaxy S6 Edge, according to a report from SamMobile. The smartphones are expected to updated to the build numner XXS5DPK7. At this time, the complete number has not been confirmed.

News of Android Nougat development for the Galaxy S6 and Galaxy S6 Edge comes shortly after Samsung began its Nougat beta program for the Galaxy S7 and Galaxy S7 Edge. Pundits and consumers hope this means Samsung is aiming for a rapid rollout of the next Google operating system; however, Android 7.0 is still not expected to hit the Galaxy S6 and Galaxy S6 Edge until sometime in 2017.

The Galaxy S7 may receive Android 7.0 anytime between January and April, depending on the market and whether handsets are unlocked or carrier based. U.S. carriers in particular tend to roll out Android updates much later than other markets and unlocked models. Overall the Galaxy S7 devices and Galaxy S6 devices may see Android 7.0 much sooner than usual, considering Samsung is not developing the software for the discontinued Galaxy Note 7.

Android 7.0 Nougat originally released in August on Google’s Nexus smartphones. The software includes features such as quick switch between apps, the power-saving ‘Doze on the Go,’ direct reply to notifications and custom quick settings, among many others.

Devices that have already updated to Android 7.0 include the Moto G4 And Moto G4 Plus. Other smartphones expected to update to Android 7.0 in the coming weeks and months include the HTC 10, HTC One A9 and HTC One M9, the LG G5, LG V10 and LG G3.
