Samsung's Galaxy S7 and Galaxy S7 Edge are receiving December security updates. The update is being rolled out in India as well. The size of the update varies depending upon your current version and it brings the Android December security update as well as other stability improvements and bug fixes.
The Samsung Galaxy S7 is receiving software version G930XXU1BPL2 while the Galaxy S7 Edge is getting version G935XXU1BPL2. Galaxy S7 and Galaxy S7 Edge users can manually check to see if the update has arrived by going to Settings > About Device > Download updates manually.
The update also suggests some new features, but it is unknown at the moment as to exactly what those features might be.
Google earlier in December began rolling out the Android 7.1.1 Nougat update, which includes the December security patch, to Pixel, Nexus, and Android One users.
Samsung last month rolled out its 'Galaxy Beta Program' for Galaxy S7 and Galaxy S7 Edge users to test Android 7.0 Nougat on their devices. However, Samsung recently confirmed in a response to a user query that it will skip the Android 7.0 Nougat roll out for the devices altogether and jump directly to Android 7.1.1 Nougat.
