Samsung rolls out the September 2020 security update to the Galaxy A21s, Galaxy A51, and Galaxy A70
Samsung on Thursday began rolling out the September 2020 security update for a handful of its mid-range smartphones, including the Galaxy A21s, the Galaxy A51, and the Galaxy A70. The firmware versions are A217FXXU3ATH4, A515FXXS3BTH4, and A705FNXXU5BTH4, respectively.
News of this rollout was first published by SamMobile, who said the new OTA updates are rolling out in a handful of markets, with larger availability expected in the coming days and weeks.
SamMobile claims the September 2020 security update was first seen on the Galaxy A21s in Ukraine and Russia; the update for the Galaxy A51 was seen in Russia, and the Galaxy A70 update was seen in Ukraine.
Samsung is typically pretty good about pushing out monthly security updates, with the Korean company recently releasing the September 2020 security update for the Galaxy Note 9, the Galaxy S10 series, and the Galaxy Note 10 Lite.
You can check to see if the update is available to download by going to Settings > Software update. We don’t know if the update introduces any new features or changes, so it looks like this month’s update is simply aimed at improving your device’s security. Google publishes the Android Security Bulletin on the first Monday of each month, so we don’t have all the details on what vulnerabilities have been patched in the September 2020 security update. These devices also aren’t on Samsung’s big list of phones getting the One UI 2.5 update but it’s unlikely that Samsung won’t bring feature updates to these devices anyway.
