Galaxy A5 (2016) and (2017) were the first mobile phones to receive the new security patch for October, and now they are also following the Galaxy A3 2016. Galaxy A3 (2016). The upgrade is already available on all unbranded models and brings over 215 Google security patches, 6 additional Samsung patches and of course small improvements in device performance in everyday use.
Why did such a long delay make this update available? Samsung has encountered a problem with the Blueborne vulnerability and has spent enough time to fix the situation and protect its devices, so it puts the Galaxy A3 (2016) second, but you can start looking for a new update and download and install the file.
Other devices beyond the Galaxy A series that have recently been crafted this security patch are Galaxy Note 8, the Galaxy S8 and the Galaxy S6 Edge.
Let’s say the update is for the Galaxy A3 model (2016) with the SM-A310F serial number and if you have already charged your battery, start the OTA process.
Do not worry if you have not received an update or if the file is not, it will take a few days to show everyone.
