With so much Android 4.4 KitKat news stirring about, you’d be forgiven for forgetting that other versions of the OS do indeed exist. That said, most devices other than the current Nexus lineup and certain Moto X variants haven’t yet received the 4.4 goods in official capacity. Moreover, most end-user devices haven’t even been updated to Android 4.3.
Thankfully, the AT&T and T-Mobile carrier-branded versions of the Galaxy S III are soon to receive the Android 4.3 goods. While it’s not KitKat, at least it’s a step in the right direction. The update for the AT&T Galaxy S III (I737) comes in at version I747UCUEMJB, while the update for the T-Mobile Galaxy S III (T999) comes in at version T999UVUEMJC. So far, a few users in the forums have reported already receiving the OTA on the AT&T device.
Thankfully for AT&T SGS3 owners who haven’t yet received the update, XDA Recognized Developer loserskater has taken the incremental update from his device and mirrored it. Naturally since it’s an incremental update, you need to be on stock 4.1.2 for this to work.
You can learn more about the update for the AT&T device in this post and this thread. To update the AT&T device before you receive the OTA, head over to this post. And if you’ve got the T-Mobile device, more information about updating manually via Kies can be found on T-Mobile’s support site.
