Samsung has started pushing out a new update to Galaxy J7 (2016) units in India. Arriving as version J710FXXU3BQHC and weighing in at around 1,030MB, the update brings along Android 7.0 Nougat OS.
As clear from the change-log, the update includes changes like Samsung Experience UX, improved notifications and Quick settings button, and Multi-window mode. Given the fact that it's an OTA roll out, it might take time for the update notification to pop up, so be patient.
For what it's worth, the update has already been made available in Russia, something which happened last week.
