Official Android 4.3 Firmware for Galaxy S4 (I9500 & I9505)

Rejoice… The official Android 4.3 firmware for Samsung Galaxy S4 (both I9500 and I9505) is here. Yes, you can enjoy the latest and greatest Android 4.3 features and improvements from Samsung. However, it does bring one thing that I don’t prefer – KNOX support (which is not friendly with root access and custom modification = warranty void). So far we can’t reverse KNOX status now. The implementation is already in Galaxy Note 3 and pushing to Galaxy S4 latest firmware now. So far, India, Indonesia, Russia and Vietnam already received the update. Malaysia should come soon…

Android 4.3 Firmware for Galaxy S4

What are the improvements and new features? TRIM support will make internal NAND storage faster. Better RAM management, display colour reproduction and TouchWiz Launcher. New Samsung Keyboard, Browser, Reading Mode and Camera Firmware. And of course, KNOX Implementation too. So are you happy to upgrade?


  1. Note 2, 4.3 Update.

    I would like to ask you, I have recently rooted, installed cyanogen mod on my galaxy note 2 n7100 and I was not happy with the battery life of it so I reverted it back to stock ROM 4.1.2.
    On my recovery it says there are two counts(binary) but it says that my ROM and device is official.
    I wanted to know, will I still be able to update my phone to 4.3 official with the two binary counts? Currently I am able to check for update using the Setting-About Device- Software Update. And it says that my device is installed with the latest updates.

    I hope you can clear my doubts.

  2. Hi Jayce, I would like to ask you what is the difference between ROMs in four files (PDA, MODEM…) and ROMs with all integrated in one file.

    I have read that ROMs divided in four files are more stable and can solve problems (briks, reboot…) which one-file ROM cannot solve. Why?

    Thank you in advance.

    • No different if the whole firmware consist all 4 parts too. Just to ease you when you want to install modem only instead the whole firmware.

      Firmware might not include modem, bootloader. So it might have issue when new PDA requires them.
