AT&T has begun the process of rolling out an update for the Samsung Galaxy S7 and S7 Edge on the carrier’s network. The updates for both devices are small at 46.5MB and bring the Android Security Update patch to the December 1, 2017 level. The patch also brings a fix to the BlueBorne Bluetooth exploit on both devices.
For the Galaxy S7, the updated build is G930AUCS4BQL1 while for the S7 Edge, you are looking for build G935AUCS4BQL1. Given the small size of the updates, you can download them via your mobile data account but it is always recommended that you download them via WiFi. After it is downloaded, expect about a 10-15 minute install and a required reboot.
Beyond the update to the Android Security Update patch and the addressing of the BlueBorne vulnerability, the release notes for both updates indicate there is nothing else in them. Usually carriers (or manufactures) will throw in a few performance fixes in every update but if there are any in these, AT&T has not indicated it. The update size gives a hint however. Given it is so small, it is likely just the updates and nothing more.
The updates will be pushed out to Samsung Galaxy S7 and S7 Edge devices on the AT&T network over the course of the next few days. If you want to manually check for it, you can by going into Settings and System Updates on the devices.
