Even though the Samsung Galaxy S4 has just arrived at AT&T for less than a month, the carrier has already begun to push out the first ever update to the device according to sources. This is a minor performance update weighing just 21.39 MB, which apparently fixes the lag on the home screen as well as increase the device’s available RAM for usage. As of now, AT&T has yet to release the official changelogs for the update but it’ll definitely arrive sooner or later.
This update is available for download through Samsung’s PC companion Kies or via over-the-air (OTA), which is a much more preferred option as you can download it directly onto the Galaxy S4. Do tell us more about your device after you’ve installed the update.
