Remember how AT&T pulled the Android 4.3 update for the AT&T variant of the Galaxy S 4 (I337) a couple of weeks ago? While there was no official word as to why, many users speculated that the same issues facing the international SGS3′s 4.3 update were plaguing the AT&T S 4. These included issues such as wake up lag, random freezing, battery drain, Bluetooth audio issues, stuttering music playback, freezes, poor multitasking, and WiFi issues.
Thankfully, it appears as if the issues have been resolved and the OTA is rolling out once again. This time, with a new version number. Rather than the previously available Android 4.3 I337UCUEMJ9 build, today’s update comes in at I337UCUEMK2.
In case you haven’t received your update already, you’re in luck, as these builds have since been mirrored for your sideloading pleasure. Naturally, there are two incremental OTAs available: one for users on the previous 4.3 build (MK2) and one for users on the latest 4.2.
XDA Forum Member mqlin went ahead and mirrored the update for those already running the previous Android 4.3 OTA for the device (MJ9). This is a small, 28 MB update to take you all the way to MK2. And if you’re running the older build, XDA Forum Member pvtolson has you covered with the full 727 MB update.
If you’ve already gotten the update, please feel free to leave your feedback in the comments below. Also, don’t forget to join in the discussion over in the AT&T Galaxy S 4 forum!_________
