Following the AT&T and T-Mobile versions, the Sprint and US Cellular versions of the Samsung Galaxy S3 are currently receiving over the air updates to Android 4.3 Jelly Bean.
For Sprint users, the Android 4.3 update for the Galaxy S3 will bring the firmware version to L710VPMJ9. The biggest changes involve the addition of the Samsung Knox security suite and compatibility with the Galaxy Gear smartwatch (which apparently has been selling better than anyone expected). The OTA also upgrades some of Samsung’s applications, including Group Play, Multi-Window multitasking, which now works like on the Galaxy S4, Sound and Shot camera functionality, and the addition of Samsung Link. There’s also the usual bevy of bug fixes, as well as all the good stuff that Android 4.3 brings under the hood, including Bluetooth Smart and OpenGL ES 3.0.
The Android 4.3 brings the same features to the US Cellular version of the Galaxy S3, with Samsung Knox and Galaxy Gear support front and center. The bump changes the firmware number to R530UVXUBMJA.
If you’re an owner of a Galaxy S3 on either Sprint or US Cellular, you should receive an OTA notification anytime soon. Go to Settings > About device > Software update to check for the update manually, but don’t forget that all you can do is be patient.
