Back in April, owners of the Samsung Galaxy S4 Active were treated to the ultimate tease when an update to Android 4.4 KitKat began rolling out, only to be put on hold a few days later. The only explanation was a claim that AT&T and Samsung were "looking into potential improvements." It looks like the time has come -again- for the S4 Active to make the jump to KitKat.


What's changing?

  • Android 4.4 OS upgrade (
  • Copy and paste improvements
  • Easier to insert pictures and videos in email or messages
  • Camera app accessibility from the lock screen
  • Call reliability improvements

The changelog is a bit lighter than the one posted on the previous attempt. Still, the baseband and build numbers are different, so it's safe to assume something has changed. It's possible this was in response to some recently exposed security issues, including the Heartbleed bug, which was only discovered shortly before the rollout began.

This update will eventually auto-install on its own, but if you're eager to get it right now, just hit About device > Software update > Check for updates. If you already installed the previous update to 4.4.2, the update should come in at about 67 MB. Otherwise, the download may be as large as 841 MB. Regardless of size, you'll have to be connected to a Wi-Fi network to start the download.

  • Baseband version: I537UCUCNN3
  • Build number: KOT49H.I537UCUCNE3
