Just a few hours ago we got our hands on the first leaked firmware of the Exynos 5 octa-based Galaxy S4 (GT-I9500). Right now, updates for some regions are already seeding away so keep checking your device if there’s any OTA update or better yet use Kies on your computer to check for the update.
The update comes a day after the I9505, the LTE variant of the Galaxy S4, got its Android 4.3 treatment. The update will roll out to all regions over the course of the next two weeks most likely. Since almost everyone will be after the update, you may not be so lucky getting it so checking samfirmware.com regularly to see if firmware for your region is available maybe the most prudent thing to do.
Also, if you flashed the leaked test firmware, there is nothing more for you to do. I’ve looked at the changelogs, it is the same thing. Actually the leaked firmware was a final build.
I am currently using the firmware and there is so much more that it brings to the table. Under the hood improvements are the biggest since there’s hardly any lag or the occasional stutter that we have come to associate with Samsung’s implementation of Android. There’s a nice new keyboard, revamped S Health app, Samsung apps, email app, the Samsung web browser and the addition of reading mode in the settings toggles.
