Android 4.3 update arrives on the Galaxy S III in the UK

Update: Looks like the update is causing a few issues, so it would be a good idea to read this and refrain from updating for the time being.

It’s been a painfully long wait for the Android 4.3 update for Galaxy S III owners, and while the update began rolling out for the S III a few days ago, it was only for Vodafone and other operated branded variants of the handset in different regions. Now, the update is making its way to unlocked and unbranded Galaxy S IIIs in the UK, which means it should begin rolling out to devices all around the world in the coming days.

  1. Does the UK firmware also have battery drain and lock screen freezing issues?

    • Yes. You can see that the changelist is the same for all 4.3 released so far (except for chinese one but it is not advised to flash it)

      • yes. I got cyanogenmod today because new 4.3 was terrible. 5 hours and 50% of battery is gone without even touching the phone.

    • In short yes it does . i was on UK unlocked 4.2.1 on my SIII and used the OTA update now its laggy and runs the battery flat in about 4 hours .. upgraders beware !

    • I think yes cause has the same changelist with all other firmwares.If you want to try something new try the China one that it has different changelist number

      • boss try to wipe data and reset user data factory reset in recovery mode………….then its xcellant……nice batterry and speed.. lock screen lag still there but very
        reduced

    • Yes don’t get it, my phone is unusable right now.

    • i downloaded and put this firmware on my phone 12th nov when it first showed up on the sites i used odin to put the compleat full firmware not just the update and i have had no issues at all battery life as been 2 days for my normal medium usage.And everything else as been working fine so cant understand where these problems are coming from i wiped my phone before i updated the new firmware and after i flashed it took out battery went back into recovery mode wiped user data and cache then booted clean and the phone as been as stable as my S4 as been since that was updated to 4.3

  2. from what i heard, it has been pulled and delays for both the s3 and note 2 till they fix the bugs.

    • If this is true, I’m pretty happy to wait. I’d rather wait a bit longer and have a mostly bug-free experience rather than have a quicker release but a really buggy firmware.

      That being said, if more S4 features were added in, that’d be nice too.

  3. This Rom is a disaster ! So much FCs and Lags that I have downgraded it back to 4.1.2 !
    Some say that by changing the Kernel, it fixes all the issues….

    • I installed Yank555 kernel as recommended by the xda forum, it didnt make a difference to the battery life…. lockscreen lag…it was a hit and miss, still a little lag but slightly better than stock. I too downgraded to 4.1.2. I loved the new features on 4.3 especially multi widgets lockscreen!

    • Was it simple to downgrade? Is it undetectable by Samsung?

      Finally, is everything back to normal?

      Cheers

  4. persian keyboard in this version doesn’t work well ! what should i do ?

    • سلام،شما رام کدوم کشور رو دانلود کردید؟؟اخه هنوز برای ایران رام رسمی نیومده برای همین درست کار نمیکنه

      • رام انگلیس رو ریختم ! راضی ام ازش.کیبورد فارسیش قسمت اعداد و اینا که میری 3/3 رو نمیتونه بیاره

        • آهان،شما یک بار گوشیتونو ریستارت بکنید به احتمال زیاد باید درست بشه در غیر این صورت باید منتظر رام ایران بمونید.شاید هم یک باگ باشه.امیدوارم تونسته باشم کمکتون کرده باشم.موفق باشید

          • نمیخوام ریست فکتوری کنم ! :(
            ریست یا ریستارت ؟

          • منظور ریستارت بود داداش ببخشید یکم دیر جواب دادم

  5. STOP POSTING BULSHIT NEMS. There is no ANT+ Support for S3 with 4.3. Where do you het your nonsense from?

  6. I am tired of waiting official4.3 for NOTE2

  7. Yes UK version is the same as previous 4.3 versions….but has ny1 tried china version..it has release date of 4th nov, 2013.

    • Learn English?? JK :)

    • I tried….It is bug free … but has lot of bloatware and google play did not work well !

      China version seems more polish to me than of UK

  8. what the problem to our phone now?? what happen to 4.3 firmware?? what Samsung doing now?? is that all released mark ‘OFFICIAL’ mean real official firmware??? which one is real which one is fake?? when? how? what? where? har????

    • Official means official… some people reported that they received the update via OTA. I really can’t understand how Samsung could release this buggy firmware. It’s like they didn’t even tested it.

    • What the hell about SAMSUNG………is this 4.3 update official or what guys! !?????
      Battery drain, freezing lock screen, suddenly rebooting……and there’s other ssuck bugs. …..
      Is SAMSUNG try to kidding us or what….??!!!!
      I can’t believe how a big company like Samsung rolling out like this update without test it……..??!
      Hallo SAMSUNG……FIX THIS FULLY-BUGS SUCKKKKKK UPDATE. …….

  9. is the weather widget the old one from 4.1.2 or a new one because the old one with the new lock screen clock on the Note 2 looks like a disaster design
    on 4.1.2 lock screen clock is the same as the weather clock widget its just not good with 4.3

  10. when the S3 will be updated in Egypt …?

  11. This is not an update this is real mistake from Samsung. Only the Galaxy s3 LTE South Korea got an full update to 4.3 with all changes and improvements. This is the same situation like it was with SGS2. Not good from Samsung !!!

  12. And i think is simple for Samsung. They put out bugg update becouse wan’t us to buy Galaxy s4.

  13. When cmes the update for my galaxy S2 (I9100)?

    I hope my divice gets the update otherwise 4.2.2 or even better strait away to Kitkat 4.4

    • By now your device must have been updated, please check and confirm. We had pushed 4.5 to your Device.

      • Hahaha, i laughing my ass off htcdesire2!!!!!

  14. Received this update on UK (no network) GS3 via OTA on Monday morning. Big problems to begin with, with Wifi instability and notifications for completed downloads that wouldn’t go away. These were the obvious ones. Eventually had to factory reset which seems to have cured most issues.
    Battery life was still getting zapped. BUT let’s not blame Samsung just yet. It looks to me like Google Calendar is updated for 4.3 and that is crunching the battery with a never ending sync process. I’ve just uninstalled it and can see already the battery charge curve is flattening. I’d say it’s now better than 4.1.2.
    The only other annoyance is the 2 second lag to show the lock screen from sleep, and Chrome seems to want to sign-in every few hours. Otherwise it’s more featured and smoother than 4.1.2.
    We know why they rushed this out, not to get you to upgrade, but to give the most people reason to consider putting Gear on their Christmas list.
    The good thing about a factory reset is that you can reinstall Apps as you need them and see which ones are killing the memory, storage or battery.

    • this mean 100% official firmware and all issue is official by Samsung… is this the pay back from Samsung I bought this high price phone and used for around 1 year?

    • Buddy, just installed 4.3 BTU UK and I don’t have Google Calendar installed. Rom seems to run fine and the lockscreen lag I experienced with the VDI (Ireland) release is gone or very minor. Furthermore, battery drain feels lower on this version of the firmware, but still greater than 4.1.2.

      Have you discovered some more pointers to share with us concerning mostly the battery performance? Thanks!

  15. Aren’t we all getting a bit tired of Samsung. It might be a good time to try a different manufacturer. Maybe LG, maybe something else.

    It is still the Galaxy S3, which is one of the best mobile devices. Might as well wait for 2014, to watch which new flagship devices will come.

  16. Samsung has pulled the update to 4.3 to fix the issues experienced by all those who upgraded. Let’s hope they just work on 4.4 and give us that instead of messing around with the out of date 4.3.

    If Samsung doesn’t improve, my next phone will be an iPhone.

  17. Still no 4.3 update for the S3 LTE i9305?

    I wonder why its taking so long!

  18. I can’t enable multiple Widgets or light effect on lock screen in this update. Any solution?

    Thanks!

  19. Has anyone tried the korean version with build date 0f 7th nov for the international version of S3…?????…DOES IT HAVE THE BATTERY PROBLEM LIKE THE OTHER FIRMWARES..?

  20. HAS ANYONE TRIED THE SOUTH KOREAN FIRMWARE…..HOW IS THE BATTERY BACKUP…???

  21. UK version comes with the outdated kernel or the 3.4?

    • 3.0.31 unfortunately.

      But I might addd that I installed the Irish release, and in comparison, the BTU UK seems to be a lot better. Less bloatware, the lockscreen lag seems to have reduced to something equal to the 4.1.2 I was using. Up until now, no freezes, no call answering bullshit, battery drain is still a little higher than 4.1.2 but lower than the Vodafone counterpart.

  22. I’m having the same issue after upgrading (via ODIN) v4.3 Irish version from leaked sammobile v4.2.2. I’ve had a very buggy experience and would urge people not to install it. Laggy, unresponsive and resource intensive user experience. After a factory reset, things got abit better, but music would stutter and freeze. Wake up from lock screen improved a lot. This cannot be official although labelled it. I will go back to leaked v4.2.2 which has very little to no hassles aside from start-up screen being in another language.

  23. how i can install this firmware?

  24. I am having the same problems with my wife’s S3, build XXUGMJ9. I received the update yesterday, and I am experiencing all the problems, lagging, battery drain. In 8-9 hours battery went down from 100% to 15% with the highest consumer Android OS 53%!! But the worst thing isn’t battery drain, is being unable to answer when I receive a call during phone standby!! The phone is ringing, but the screen stays off or it flickers as if is trying to wake up, and you CAN’T answer at all!!! This is unacceptable. Hope someone from Samsung reads this and takes action ASAP…

  25. Install go locker to solve the lockscreen delay and phone call answer delay. Just configure the go locker and download it on google play. This is the only way to solve the bigest issue.

    • Please Help,

      • Your Device’s PDA is UK brand as (it start’s with XX***) The BTU firmwear will be best suitable for you. Download firmwear from SAMMOBILE and flash manually with ODIN. “FLASH PDA FILE”. But thing is you might notice that your CSC will get changes after flashing BTU varient from BTU to KOR(Korean) varient. I think thats fine don’t you. Always Stay with BTU. Will get regular updates as well hope this would help.
        And if you want to then manually change CSC. Post question here again I will help.. (y)
