Both the flagship handsets from 2016 and 2017 are getting some care from AT&T in the form of a firmware update. Not much was made clear by the source of the news or the change log, but it is clear that this is a security update. Whether this is any version of the Android monthly updates or not is something that we are not sure of either. In any case, you should download and install it as soon as possible, since carriers in the US seldom push out updates unless they are necessary (that’s not always a good thing mind you!).
The update is arriving on all the six models in the Galaxy S7 and S8 series, which include the S7, S7 Edge, S7 Active, S8, S8+ and the S8 Active. As per The Android Soul, the following are the firmware build numbers for the respective devices.
S7, S7 Edge and S7 Active: BRD1
S8 and S8+: CRD4
S8 Active: BRD4
Unfortunately for S7 users in the US who are on AT&T, all three devices are still running on Android Nougat, in spite of the OS being on the verge of becoming outdated.
