Android 4.3 is eventually making its way to all versions of the Samsung Galaxy S 4. Following the Sprint and Verizon S4s getting 4.3 last week, it’s US Cellular’s turn to get the new software. In addition to 4.3, firmware version R970VXUAMJA brings Galaxy Gear support, Samsung’s KNOX enterprise security suite, and various bundled apps including Mobile TV, Slacker Radio and Amazon Shopping.
We’re still waiting for 4.3 to land on the AT&T and T-Mobile S4s. According to a leaked timetable, it looks like they will come on November 13 and 18, respectively.
