A minor update is being pushed out to the Galaxy S4 Active on AT&T, build number I537UCUCNH3, filled with fixes for network connectivity and security patches.
In the official changelog posted on AT&T’s support site, the company notes that connectivity improvements related to receiving calls and text messaging, a single security patch, and a few updated Google applications are included.
Beyond those additions, the update is rather small.
Go grab it.
