Shortly after beginning to push the Android 4.3 update for the Galaxy S4 on AT&T as build 1337UCUEMJ9, issues arose causing the rollout to be stopped. Parties involved reportedly confirmed that there were issues and that they were investigating them, though no new timeline for a rollout was given. According to an update to AT&T’s Galaxy S4 support page, today is the day that 4.3 will resume, only this time as build I337UCUEMK2.
The update weighs in a little more as well at roughly 727MB. Other than that, it should be exactly as you were expecting when the first update began. Here is what the changelog shows:
- Android 4.3 OS upgrade (www.android.com/whatsnew)
- Samsung Galaxy Gear compatibility
- Drag and drop to uninstall or disable applications
- Call reliability improvements
To try and pull the update, head into Settings>About phone>Software update>Check for update. The update is supposed to “effective” as of today.
