Flash Android 7.0 Update for 2016 Samsung Galaxy A3 and Fix Charging Bug

Samsung has come with its latest Nougat update for all the Samsung Galaxy A3 2016 European users. This update carries a shot for the charging bug that was prevalent in the previous firmware.

The new Android 7.0 build date is fixed for 28 September 2017, and the Security Patch level is August 2017. If you are having a newer firmware, just ignore this article, as no charging bug is on your device.

The Galaxy A3 2016 charging bug doesn’t enable devices to charge to their maximum capacity, as there are various users claiming that their devices don’t gobeyond 87%. However, the new A310FXXU3CQI8 Android 7.0 Nougat firmware update will provide solution to this problem and users would be able to charge their devices to their full capacity.
