AT&T Galaxy S7 and S7 edge updates version G930AUCS4APK1 & G935AUCS4APK1

AT&T Samsung Galaxy S7 and Galaxy S7 edge are getting an OTA update that has just bumped up the device Android Security patch level to November 1, 2016. The update will now move the AT&T's Galaxy S7 to version G930AUCS4APK1 while the Galaxy S7 edge to version G935AUCS4APK1. It's basically a minor OTA update considering it file size for just around 50 MB, so we cannot expect anything new about it. The update is still base in Android 6.0.1 Mars-mallow OS, and it's not the Android Nougat update yet so far.

Furthermore,the Android Nougat beta is already hitting the Galaxy S7 and S7 edge in the US. But noting that AT&T Galaxy S7 and S7 edge has not participated the said Android beta program event for some other circumstances, so we cannot speculate more about AT&T's movements.
