Android 4.3 Firmware for Galaxy S3 GT-I9300 is Available Now


It’s true that Samsung sends the latest Android updates to most of its deserving devices but but considered from the angle of timing, they are often late. At a time when the air is filled with aroma of KitKat, the OEM has turned on the wheel of Android 4.3 updates for a range of its devices. The update is already out for the variants of the Galaxy S4 and now the users of Galaxy S3 GT-I9300 can feel a little happier with the all new Android 4.3 Jelly Bean firmware update.

It was just a couple of days ago that we shared the leaked version of Android 4.3 test firmware for Galaxy S3. Today we have the official build of the ROM that you can install using Odin. Please note that the released firmware is a branded one and it means that it is for the Galaxy S3 users in Ireland (Vodafone). We tested this firmware on our unbranded S3 and it worked without any issue. If you do not wish to install it, you can wait till an unbranded firmware comes out because it won’t take much time. If you want to get the new update via OTA, go to Settings> About> Software update and check for the new update.

Features and Changes:

Android 4.3 Jelly Bean is definitely a big update for the users of Galaxy S3 as they have been on Android 4.1.2 for a long time. Besides bumping your phones Android version to 4.3, this update also brings a lot of new features, changes and improvements. We have made a list of the new changes that we could notice:

  • Galaxy S4-like lockscreen with personal message feature
  • Multi-pages on lockscreen

  • Tabbed UI in Settings
  • Daydream feature

    Hi Rakesh,
    I’ve installed 4.3 update and decided to go back to 4.1.2 successfully without losing my IMEI. I want to root my device now on 4.1.2 xxemg4. I dont want to install custom roms, i just want to remove some bloatware from my device. only reason why i want to root. Will rooting only increase my binary counter? Thanks

  • Sum

    I have just updated my Galaxy S3 with Gellybean 4.3 from 4.1. I have the two following major problems,
    – Screen mirroring is not working. It was working fine with 4.1 version, I use PTV3000.
    – Sansung link app is not working for connection to Samsung Accnt.

  • Yes.

  • Poly

    reinstalling the firmware means update again, right?

  • Tested myself, works fine. You can use it till the official version for India arrives.

  • Kapil Singh

  • Wibisono Tan

    or just share me most safety link for me…
    thanks in advanced…

  • Did you do a data factory reset after installing the ROM?

  • Ahmed Nizam

    Hi, I did install it successfully, but I have two problems:
    – When i leave my phone to lock automatically, after few minutes the system crashes and if i press the home button it needs like 1 minute to show the lock screen.
    – About the new keyboard, i know many people who got this update and now they have emoji in their keyboard, but when i press and hold the button next to the space bar i don’t find emoji as one of the options.
    *I have the Irish version of Android 4.3

  • Yes you can.

  • Wibisono Tan

    i want to ask that if i backup my imei for i9300 in jelly bean 4.1.2, can i restore imei to the same phone but already updated to 4.3 jelly bean?

  • Jérémy Devez

    Odin’s steps goes well. No fail. but once rebooted, I did not superSU and installing after it displays the message “no SU binary is installed.” As if the root did nothing.

    ps: sorry if I’m not understandable
    And thank you for the quick response.

  • Both are the same versions and will work equally good. The difference is the carrier branding and boot logo.

  • Sebastian Liviu

    Hello please tell us if this firmware works for evrey base band version and version number for an example jzo54k ? And what is the differences of the swisscom version or the ireland version? Are the same or just the boot animation logo is different? Tanke you very mutch and y am waiting for a answer.

  • What error are you getting?

  • Jérémy Devez

  • Aakash Srivastava

    Hi Rakesh, thanks for the most stable firmware ….i had downloaded it and installed on my phone yesterday…only lag i am facing is….when every i am pressing power button screen s boot up normally ,sometime it doesnt boot and i keep pressing power button again n again and sometime when i press power button it takes 2 sec to show up the screen.
