While Galaxy S9 owners are being treated to the Android Pie update, it’s business as usual for other devices in Samsung’s lineup. Samsung has released an update for the Galaxy A3 (2017) and the Galaxy A7 (2017), bringing the December 2018 security patch to both devices. The December patch has already been released for the Galaxy A5 (2017) in some markets.
December 2018 security patch update out for A3 (2017) and A7 (2017)
The A3 (2017) and A7 (2017) updates are rolling out in a number of countries, with software versions A320FXXU4CRL1 and A720FXXU6CRL1 respectively. The December 2018 security patch fixes 40 vulnerabilities in Samsung’s software and six critical ones discovered in the Android OS. One of the major vulnerabilities with Samsung’s software allowed access to Secure Folder gallery images without authentication, so the December 2018 patch is a recommended download for everyone.
