Download Android 4.3 on your Galaxy S4. SamMobile has leaked the almost finished Android 4.3 firmware for the Galaxy S4 I9505, meaning if you can’t possibly wait for the sometime-in-October OTA release, and even then as a staggered rollout, then you can download the ROM and flash it to your device, right now. Keep in mind this is not the final build, so it may be a little buggy – although SamMobile report that it’s stable – but it will get Android 4.3 on your rooted international LTE variant S4 in a jiffy, adding Samsung Wallet, Samsung Knox, a reading mode, better color reproduction and some other performance and speed improvements.
Before we go any further, here’s the technical details for your consideration, and as always, we remind you that AndroidPIT takes no responsibility for any issues you may encounter when rooting your device or flashing ROMs, so proceed at your own risk (sounds scary, doesn’t it?).
We’re downloading it right now and will post a tutorial with full screenshots and walkthrough of the necessary steps as soon as we’re done. But if you know what you’re doing, go right ahead and let us know what you think.
