Samsung India today started rolling out the latest Android update for the Galaxy S4 (I9500). The Android 4.3 update is available for Exynos 5 Octa running Galaxy S4 and is available through OTA and Kies. Samsung is rolling out in batches through OTA and if your phone hasn’t notified you yet, chances are the OTA quota has been exceeded. But if waiting is not what you’re fond of, connect the phone to the PC and download it directly through Kies.
It’s a big almost 700MB update and brings in many new features like Reading Mode, KNOX support for enterprise users, TRIM to improve phone’s performance, Galaxy Gear support, new camera firmware and lots more.
