December security patch update arrives on Galaxy A3 (2016) and A3 (2017)
Galaxy A3 (2016) and Galaxy A3 (2017) owners can see if the update is available for their device by tapping the Download updates manually option in the Settings » Software update menu. The update will take time to propagate to all regions, so if it isn’t already available in your country, be sure to check again in a few days. It’s possible not every country will see an update with the December patch, as Samsung doesn’t release regular updates for non-flagship devices. In that case, you’ll just have to hold out until the company decides to release an update for your country with the most recent security fixes.
