A second Android 4.3 Jelly Bean update for the Samsung Galaxy S4 (GT-I9505) has leaked. Unlike the first one, which surfaced earlier this month, this is not an early test version, but rather “one of the final builds.” The update is expected to get its official release in 1-2 weeks, but you can download and install it early if you know how.

Like the first leak, this one comes from an insider for SamMobile. They report that they’ve tested the firmware for two days prior to releasing it, and they’ve noticed a number of improvements over the early test build. There are no “major changes,” however.

If you can’t wait for Samsung to make the firmware available to the public, you can download the package and install it manually. It’s a fairly simple process if you’re comfortable with flashing ROMs, and SamMobile insists it will not void your warranty of increase your binary counter.

To download the firmware, just click the source link below and follow the instructions form SamMobile — then leave them a nice comment to say thanks.
