AT&T Samsung Galaxy S4 owners in the U.S. have received the 4.3 Jelly Bean OS update.

Samsung did not openly announce the release of its latest Jelly Bean update, but the software upgrade brings Bluetooth enhancements and support for the Galaxy Gear and the Bluetooth LE support that comes with Android 4.3.

Several weeks ago the 4.3 Jelly Bean update first landed to Samsung Galaxy S4 in the U.S. through Verizon and Sprint carriers. Recently, U.S. Cellular has released features found in Android 4.3 Jelly Bean and support for the Galaxy Gear accessory.

AT&T Galaxy S4 Android 4.3 Jelly Bean update has also recently been launched. However, the update could take a day or two to show up. Networks are known for staggering the updates before making the upgrade available to many users. Users are advised to remain patient as the roll out will be randomly and there is no way to predict when it will arrive.

AT&T is one of the biggest carriers in the U.S. and its update is vital since quite some of Samsung Galaxy S4 users are under the aforementioned network.

Since then, we have seen even more activities for Galaxy S4 owners in the U.S. and here we take a final look at the Galaxy S4 Android 4.3 roll out in the U.S. in an effort to help users set expectations.

In October 2013, Samsung has announced that the Galaxy S4, Galaxy Note 3 and the Galaxy S3 will receive the Android 4.3 Jelly Bean update in the future although the company did not give out specific dates. However, there is a lag in rolling out the updates for the Galaxy S3 and Galaxy Note 2.

Now that the 4.3 Jelly Bean update for Samsung Galaxy S4 is out, Android 4.4 KitKat OS update will surely follow soon although Samsung has not yet confirmed anything. It is speculated that Samsung Galaxy S5 will be the first smartphone to pack Android 4.4 KitKat OS aside from the Google Play Edition of Samsung Galaxy S4.
