Our inbox and forums are chock full of folks screaming about a new OTA update hitting the AT&T Samsung Galaxy S4. Indeed, there is one, and it’s about 27MB in size. The update doesn’t seem to change much on the surface, but there have been consistent reports of smoother performance across the board. Particularly, a slight lag that was bothering folks before seems to have eased up.
This update also breaks root, but we hear existing methods are still valid for getting it back. It’s not yet clear if AT&T is targeting the same bootloader exploit Dan Rosenberg found, but if you want to be absolutely certain that you’ll be able to use Rosenberg’s method when it’s released it’s wise to hold off on the update until we have more info. If you don’t care about any of that stuff and you just want a smoother device check for it by visiting the settings menu (but make sure your battery is charged and you are on WiFi beforehand).
