Just last week, we reported that AT&T was beginning the rollout of the Android 4.3 update for their variant of the Galaxy S4. This update also included a slightly updated version of Touchwiz and Bluetooth 4.0 Low Energy support, which is needed for Galaxy Gear. It appears that now AT&T has pulled the update for some investigation. So those that are waiting on the update, can stop spamming that Check for Updates button.
Currently, there's no word about when the update will continue its rollout, or even what the issue was that caused the rollout to pulled. Hopefully we'll learn soon what the deal is. At this point, Samsung and AT&T have said that the update is on hold so both companies can look into "potential improvements".
We've already seen a near final build of Android 4.3 for the Galaxy Note 2. Which is the next device to get the Android 4.3 update along with the Galaxy S4 Active and the Galaxy S3, all before Christmas. We also haven't seen the Android 4.3 update hit any other Galaxy S4 yet besides the Verizon one, which was first, surprisingly. As far as this update goes, this really isn't about Android 4.3 as much as it is Bluetooth 4.0 LE support, which makes the device work with Samsung's smartwatch, the Galaxy Gear.
Samsung was still pretty fast at updating their devices to Android 4.3, in fact they were the first to release a device with Android 4.3 out of the box. Well, first device that wasn't a Nexus. Android 4.3 was announced in late July, and to see devices getting the update before the end of this year is actually kinda surprising. But it's a good thing. Hopefully AT&T and Samsung can get the kinks worked out and get this update back on track for all the AT&T Galaxy S4 owners out there. If any of you have recieved the update, let us know if you're having any issues with it.
