Xperia Z1 Compact_14.3.A.0.757Sony is now rolling out the Android 4.4.2 KitKat bug-fix, just as it had promised last week. Firmware build 14.3.A.0.757 replaces the previous KitKat build (14.3.A.0.681) and fixes the sound bug issue which frustrated many. The issue related to sounds from the handset being played through the internal, rather than the external speaker.

The update is rolling out across all variants of the Xperia Z1, Xperia Z Ultra and Xperia Z1 Compact. We have included a list of regions where it has currently hit right now, however expect this to broaden over the coming days. If you’ve downloaded it, let us know if it fixes all of the issues you’ve had with the new KitKat build.

    Can you brief the bugs, I have been using the Z1 and except for the lockscreen wall paper issue and the lockscreen music widget where i dont get the album art refreshed when the songs change, i didnt notice anything.

  • Mohammed Khired

    maybe means “Unknown” …

  • Fafiq

    He’s right, it means “I don’t know”. ;) Trust me, I’m from Poland

  • Micro

    wouldn’t be that funny, “nieznany” = “unknown”, but “nie wiem” has the very same meaning as “I have no idea” or “I don’t know” :]

  • ProWeirdo

    No. It really means “I don’t know”. That’s weird, they could write “unknown”…

  • Kaarthikeyan Swaminathan

    Hmm, interesting, I am a heavy user. I am on wifi close to 6 hrs a day and otherwise on 2G network and 3G if needed. I play few HD games like 2 hrs, on whatapp chat that can go upto few 100 msgs across 4 hrs. Random foto shots and mayb 30 min to 1 hrs music on BT. Frequent email check on chrome. and 2 hrs of voice calls. I get close to 18 hrs. Mayb you should check if any of ur apps are trying to write on the SD card but cant due to google restriction. check if the media server service is killing the battery. If that is the case you can remove the SD card and reboot the fone and then add the SD card.

    Download call log manager, then delete the call log from it. After that start making calls and it should appear on your call log

    Think about it this way, how much support do samsung and HTC give their mid range handsets? In my opinion Sony is the best when it comes to update or releasing new firmware updates for mid range handsets :p

  • Adrian969

    I feel sure that Z will recieve a simplified version of 4.4 with lots of the new features from Z1/Z2 not avaible. Probably it will be some annoying bugs too that will not be fixed, making people want a new phone.

    Just like what happened with X10i and the 2.3-update, a annoying soundbug that maked musik skip a bit while listening. It never got fixed by Sony. Or the Arc that got 4.0 but with lots of preinstalled apps that was unnesecary but could not be removed, wasting 50-10MB of internal storgare that was needed for other stuff. The result was a slow phone that always run of out storage for apps.

  • grav1ty

    And that’s why so many people fucked up when Sony is releasing so much smartphones. They just ignore even 1 year old devices. As a customer, you will always have the shorter one. Trust me, too many Flagships arent good for customer experience, if they can’t (better won’t) support it. Forget those new Features with new Versions of Android, they don’t even fix bugs, which where there while it wasn’t 1 year old. And when your device has passed the “Sony-Support-Time-Frime”, they say “Sorry guys, but we do not support this very old crappy device any more”

    You are reading this from a Sony user

  • Adrian969

    Yes. But still Sony is the best at market right now. The other are doing worse with their models.

  • the M

    Im downloading it in Egypt now

  • Deki

    Are there any other big fixes except sound issues?

    I’m waiting for it…

  • Danni Kristensen

    1. Open Call Log Monitor
    2. Check all items on the list, and delete them using the bin in the top right corner

    TIP: The calls are sorted by date, and you can just check the date fields. It’s a lot easier.

    After that, open your phone dealer, and make a call. It should now appear in the call log area.

  • Z1CompactUser

    anybody who got new updates on movies 6.2.A.0.8 ?? New ui and it good access on movies app.

  • JP

    I just received the Movie update. Yes, it has a new UI, but I am still experiencing the bug in which I cannot find certain movie information via the integrated Gracenote. For example, I search “Thor” or “Pacific Rim”, the app tells me “No network available blah blah”. This used to work before the 4.4 update.

    I guess this is a 4.4 bug rather than the app itself? I’m still waiting for this system update that hopefully fixes not only the sound bug, but other bugs as well. I really getting impatient with Sony. :(

  • mercast

    Hahaha. That’s so accurate and witty. I agree.

    i’m still currently at 4.3 jb(didn’t update due to the comments/bugs i’ve read on the first kitkat version). do i need to upgrade to 14.3.A.0.681 first then to

    14.3.A.0.757 or can i upgrade straight away?

  • grunt

    seems like the audio bug has been fixed on mine. good job sony!
    however another new bug appeared. i’ve set my z1c to vibrate mode (via smart connect, every weekdays 8-6pm sound mode turns to vibrate), but when i received an SMS, the sound mode change back to normal, and then notification sounds dinged.
    i manually change it back to vibrate, receive another sms, same thing happened.
    i hope this is just a bug from smart connect, not from kitkat itself.. anyhow, please resolve this issue!

    Happens to me at this moment with my Xperia Z1, I was waiting for the fix, thank God Sony noticed. In the meantime what I was doing to resolve the issue was going to the settings, volume, slide the ringtone to the left, let the “example of volume” noise to be hear, slide it back to full, click done, should reset volume being heard from main-bottom speaker rather than
    internal speaker.Android 4.4.2

    Just change into other theme and it will be changeable. It is because of Sony unique default KitKat live wallpaper is applied when you choose the stock theme, hence Lockscreen is locked into live wallpaper one.

    I am really disappointed with the KitKat Update for my Z1 Compact. After two weeks of use, it still feels very rushed and unfinished:

    + Soundbug is history now. Works fine
    + Design is also better than Jellybean, although it’s not a big change
    – Quickactions in the notification bar now need two clicks instead of one. Very disappointing when driving.
    – battery seems to be drained slightly faster than with JB (however, google promised the opposite with Kitkat)
    – from time to time my phone seems to freeze with no reason. For example a few minutes ago, when my alarm clock rang and I was not able to deactivate it (the screen didnt accept an input). Or yesterday when I was making photos and the screen all of a sudden became black, but I was still hearing the sounds of making inputs.
    – Kitkat camera bug. When starting the camera app, i get the info “camera not available”. Also seen the same problem with my friend’s Z1 and on my brother’s nexus.
    – not able to write on my SD Card with Airdroid because of Kitkat’s restrictions

    Anyone else who also experiences the same problems?

    You can’t get KitKat OTA. You need to update it with Sony Update Service (Windows) or Sony Bridge (Mac), as the Update is 1100MB big.

  • Nicola Lombardi


    From The Netherlands update Xperia Z1 complete.
    Provider: T-mobile, finally it reached.
    I have to say, it’s a nice update design-wise, still have to test the rest like camera, walkman etc etc.

    So far just one little annoying sound when pressing back.
    I was able to remove it after disabling the keypad sound and vibration.
    Device get’s heated up like crazy while using full brightness, also the battery empties very fast. It’s nice to have a crispy beautiful Triluminos screen but come on Sony it has to be battery efficient. Might as well do not have that glorious display, if for battery reasons I’m oblige to put the brightness on a minimum to have 3/4 day of battery life.

    I’ve always been a Sony mobile fan since the P900 forwards, I stopt when the galaxy S1 came out. I started to use Sony again since the Xperia Z (amazing design), now I upgraded to Z1.

    Come on Sony stay on track you guys have the hardware, now fix software to work properly with the hardwarde!

    What a coincidence, I’m an orange.

  • Ralph

    Just updated firmware. Been using it in few hours straight downloading content. No issue(camera, touch, heating,lag,etc) so far. :)

  • Karam Abeer

    This kept happening sometimes when I use the camera even after the update!!

  • Micro

    seems like the bluetooth problems are gone too (Z1), since yesterday the sound didn’t break even once on any receiver I tried, and the “Throw” stopped messing up with every device around. We will see, but looks (especially sounds) promising so far.

  • VJ

    Yes the Update fixes the bug…the unit is working perfectly fine. Cheers Sony!!!

  • Emil Oskarsson

    Say that to the outlet who upgraded their galaxy s3:s to Android 4.3 when the update came out. Some phones died and couldn’t be repaired :p

  • hyper0926

    Lol dont exaggerate too much. I know the s3 4.3 update was buggy but they fixed everything.


    I did dowloaded here in Panama.
    Hope they fix the battery issue. WithKitkat the battery drain faster.

    When is Z Kitkat coming? My Z is telling me it’s is hungry and what’s some chocolate….

  • Timothy Lee

    Got the update for Z1 already. (Malaysia)

  • Jani Perkiä

    YES thank you Sony! I just bought Xperia Z Ultra and I though I was going crazy since the sound came from wrong speaker at times. I was just writing you email when my phone beeped that a new update was available.

  • Kenzo Fai

    Finally! Thanks ur inform

    Is the touch screen issue solved?

  • Jaissal S

    I’m in the UK and am updating my Z1 to the .757 version right now! Through PC Companion. Yay! I bought the phone on its own without a contract.

  • Kris

    4.3 was better and more stable than kitkat ;)

  • Kris

    Seems to be a common bug, not just with Sony devices, but with Kitkat in general (my friend’s XZ, my brother’s Nexus 5 and my Girlfriends Galaxy S4 have it too). Only restarting the device helps here…

  • kokalo

    Nop,does your?

  • someone

    Can someone help me? I can’t seem to change the lockscreen on my Xperia z1. I tried everything. I turned off the phone and turn it back on, changed the theme, and.also cropped some photos as lockscreen wallpaper. How can I change the lockscreen wallpaper?

  • Alisson Santos

    BRASIL: Essa atualização estar com bug de chip da operadora. Sinal conecta e desconecta.

    change theme to earth (or anything but Air), (reboot), change it again but this time to Air and there when prompted choose the STATIC wallpaper. Reboot if needed. Helped me, problem gone forever.

    Xperia Z ultra Kitkat Bug Fix Update with New Movies App

  • someone

    Would that mean I have to reset my phone deleting my file? Or does it just mean I have to turn it off and then back on again. Sorry I’m a beginner about this stuff ans my Xperia z1 is my first ever smartphone.

  • Micro

    reboot = just turn off and back on, no deleting any files ;)
    AFAIK it’s a common problem after updating android to KitKat on xperias (perhaps not only on them), especially if you had an animated wallpaper right before the update.

    What about the z1s???

    For those who wants to downgrade back to 4.3 . Latest fix drains battery alot even on standby mode. Camera error appears eventually as well.

  • David O’Dea

    As anyone received the 14.3.A.0.757 update in the UK yet? It’s getting frustrating waiting for it, especially when Sony started rolling out on Monday 7th. I missed countless phone calls yesterday because of the sound issue, it’s unfair.
    I keep checking Sony PC companion, but no joy.

  • mohammad

    In the begining sony lied about z1 camera and with all installed updates still the camera is noisy in 20px.after that sony give us an update (4.4) that has alot of issues more than sound.problems like keyboarx disabling.touchscreen i just feel that sony lied alot.and just it was so better to buy samsung galaxy or iphone.we paid alot of money but sony does not pay attention.i test 4.4 on my z1 and my friends and we both decide to downgrade a developer and i know it well that those masterminds in sony are idiots.

  • Tim Lias

    Heads up – 14.3.A.0.757 kitkat update available now for z1 C6903 (unbranded/UK) – via Sony Pc Companion and a usb lead!!! Been using it now for 2 days and all is working fine,as far as I can see so far.

  • ryan

    Heh. Didnt fix a thing for Xperia Z Ultra.

    Well played, Sony.

  • Z1 COMPACT here, unbranded/UK. Got the Kitkat update. still have some freeze in quick cam button for the camera app, being using the update for 2 days now. and the new splitscreen with notification/quick settings is a pain in the arse, COMPLETELY NOT ERGONOMIC compared to 4.3. I am totaly let down by the lack of TAP TO WAKE, RINGTONE OFF WHEN FLIPING THE PHONE and other small ergonomic uses of the sensors that the COMPETITION IS USING SINCE 4.2/4.3… why oh why SONY ?!? Being a dedicated user for almost 10 years now… CHECK THE CONCURENCE SONY, EVEN WHEN IT COMES TO SOFTWARE.

    I updated my Z1 3 days ago and since then i haven’t been able to get the battery to last more than 6 hours. It goes from 100% to dead flat in 6hrs and thats mostly on standby and the whole time the phone is warm, if not hot. Also since the update the movies application will not recognize the mp4 movies on the sd card or the new music files i have added. Has anybody else had this issue?

  • kslawko

    Micro – This sounds like SF fo me… how did you treat your phone in terms or charging/discharging? What is its history? Did you allow it to discharge below 20% anytime, did you charge partially during the day? It seems impossible to have such long lasting battery in this fellow…

    Since updating to kit kat 4.4.2 build 14.3.A.0.757,
    Not having experienced any of the issues it was supposed to address,
    I am now having major battery issues….
    Where a full charge, 100%, would normally last me 2 days, I’m lucky now
    To have it last half a day… On stand by…. Less if the phone is used…
    From full to 55%, in the time taken to search for this thread and write
    This post….
    Anyone else with this problem..
    I see it is an issue with 4.4.2, and 4.4.3 is to be released to
    Resolve this issue….
    When is 4.4.3 being released, O2 uk?

    got the update for xperia z1 c6902 , it was only 14.5 mb, but really a f***ing update, increased the charging time into 2x normal time, means it requires 5-6 hours to fully charge and the most disappointing and frustrating thing is the fast battery draining while using wi-fi, before this fix, my z1 was working pretty well in wi-fi , but now drops to 20% in wi-fi with minimal usage. :-( . can anyone help me here?

  • Micro

    I thought I would better post a proof rather than talking about it. As you can see, no charging. almost 2 days of my completely NORMAL use – SW2 24/7, 6 hours of talking through the SBH20 + some music too (bluetooth of course), some web surfing, apps updating, several photos taken, blah blah. No wi-fi, because I have a very weak signal here and 3G drains the battery faster in this case – I intentionally disabled it to make it loose more power (it’s clear the 3G is poor on the bar) You can see there when the battery was drained faster- there was the talks (6 hours, 23 minutes, 9 seconds exactly, you can do the math so you will see how long would it stay without the talks). And it still have 33% and Stamina says one day of the battery is left, which is perfectly accurate in my case. Low battery mode is set to 10% (but I never let it drain that much, so I can’t say how long would it stay in this mode). That would be 3 full days without worry – pretty neat for a quad core fellow ;) I’m gonna let it go empty this once, I’m curious now how it ends ;)


    got the update for xperia z1 c6902, INDIA , it was only 14.5 mb, but really a f***ing update, increased the charging time into 2x normal time, means it requires 5-6 hours to fully charge and the most disappointing and frustrating thing is the fast battery draining while using wi-fi, before this fix, my z1 was working pretty well in wi-fi , but now drops to 20% in wi-fi with minimal usage. :-( . can anyone help me here?

    I have some headphones for my study of music. And I think since the last firmware upgrade I no longer support me, I need someone to help me telling me if this firmware does not support other headphones that are not Sony.
