The Samsung Galaxy S3 Android 4.1.1, JellyBean update is now rolling out for AT&T customers.
This is not an OTA (over-the-air) update and must be accessed using Samsung KIES software on a computer.
In order to update the S3 on AT&T, users must first install the latest version of KIES on their PC or Mac and then connect the smartphone to the computer.
After this step, users can then watch this KIES instructional video that will show them how to update their firmware step by step.
Once the update procedure is completed, the Galaxy S3 should be running the Android 4.1.1 build of JellyBean and the latest TouchWiz UI available for the smartphone.
Even without the help of Android 4.1, the Galaxy S3 was able to maintain its spot as the highest selling smartphone in nations such as the U.K.
According to a ranking created by the U.K. retailer known as uSwitch, the highest selling smartphone in the nation is still the Samsung Galaxy S3.
The ranking was compiled using data from live searches, pre-orders and monthly sales and features the top 10 selling smartphones in the U.K.
The iPhone 5 not only lost to the Samsung Galaxy S3, but also sold less units than its predecessor the iPhone 4S. The Galaxy S3's predecessor, the Galaxy S2, came in fourth in the rankings, selling slightly less than Apple's iPhone 5.
The list showed the top 10 selling smartphones in the U.K.
The newly released Nexus 4 was no. 5 on the list, followed by the Samsung Galaxy Ace at no. 6, the Galaxy Note 2 at no. 7, the Galaxy Ace 2 at no. 8, Sony Xperia U at no. 9, and the HTC One X at 10.
The iPhone 5 fared a lot better in its home country, the U.S.
The handset is not only the highest selling in the nation, but allowed Apple's iOS to capture to most market share in the U.S. after losing it to Google's Android previously.
The data for this report was compiled by the research firm Kantar Worldpanel Comtech and was published by Reuters in an article.
