Samsung Galaxy A3 (2017), Galaxy A5 (2017) and Galaxy A7 (2017) are officially getting the Android 7.0 Nougat only six months after launch. Android 7.0 Nougat is the first software upgrade of the flagship Galaxy A series smartphones from Android 6.0.1 Marshmallow since launch in January.

Samsung has first rolled out a feature-packed Android 7.0 Nougat to Galaxy A3 (2017) and Galaxy A7 (2017) earlier in August followed by Galaxy A5 (2017) days ago. All updates come in phases so some devices might receive them on a later date.

Galaxy A7 (2017) Android 7.0 Nougat is taking place in Thailand; the update clocks in at 1.3 gigabytes with the build number A720FXXU2BQGB. Galaxy A3 (2017) Android 7.0 Nougat is rolling out in Russia; the update clocks in at 2.21 gigabytes with the build number A320FXXU2BQG5.

The update is expected to roll out in more devices in the international markets anytime soon. For devices under mobile carriers, owners would have to wait longer for the software updates since they are subject to their approval.

Based on Google's statistics, around 12.3 per cent of qualified devices have already been updated with Android 7.0 Nougat since launch in August 2016. Nougat brings a redesigned user interface, enhanced notifications system, quick setting buttons and split windows. All devices are also eligible for the Dual Messenger feature where users can set up two accounts in an instant messenger or social networking app.
