Small Xperia Z1 update (14.3.A.0.761) starts rolling OTA [Update]

in Firmware, Xperia Z1

Xperia Z1_14.3.A.0.761_0We are receiving a number of reports from Sony Xperia Z1 owners that firmware build number 14.3.A.0.761 is starting to hit their handsets via an OTA (over-the-air) update. Up until now this firmware build had seen a very limited rollout to carriers in China and France. It appears that Sony is widening the release through the 1.9MB OTA release.

This small update moves the Xperia Z1 build number from 14.3.A.0.757 to 14.3.A.0.761, so expect only small bug fixes. Recently a new firmware with build number 14.3.A.0.769 was certified, so there may be another update on the horizon too.

Update: The update has also started to land for some Xperia Z1 Compact users too.


Thanks Felipe, Jenge, Johan and Octavio!

    and Z1 Compact

  • I’m wondering, do these tiny updates break root?

    I’m very careful now, as I barely successfully rooted my phone. I don’t want to go through the same process again.

  • John Zakaria

    Enable OTA survival mode and try your luck
    But for my experience OTA removes root if you upgrade from
    4.1 to 4.2 to 4.3 and so on i never faced OTA removing root if it was on the same android version

  • Yali AA

    You will miss the root in KiKat, go to XDA and look for the root method. that you use CWM and the Flahtool.

  • Chris

    I got an small update on my Xperia Z too it’s only 0.2 MB.

  • abhi

    Android 4.4.3 when for z1 ?

  • Tarak

    Its kinda pointless releasing this small fix when theres a newer fix already on the horizon IMO

  • That’s what I thought, but I’d rather be safe than sorry :)

    On second thought, I could always just make a backup. I keep forgetting.

  • You mean to find a ‘prerooted’ variant of this tiny update?
    Meh, I’ll just keep my phone as it is now. It works fine, there’s not much a tiny update like this could improve (:

  • Truetist

    Maybe next year near with phone deadline

  • Shravan SP

    Wait!! That .230 update is actually kitkat 4.4.2 and is not available Ota. Only pc companion and it’s over 750mb. How’d you get that?? O.o

  • Bob

    About rooting, I rooted my brothers Samsung GS3 a while ago and put omni rom 4.4.2 on it (couldn’t stand touchjizz) and it was working fine, but then he reset to factory data. It still works perfectly, but is no longer rooted and I can’t figure out how to root it again. Any suggestions?

  • I don’t think 4.4.3 is even on nexus devices yet, there’s some problem with it idk

  • Vegeta

    Its Over 9000!

  • And Mer

    Will this fix the battery problem that the 4.4.2 caused?

  • SonyCEO

    And soon Xperia S users should receive kitkat via OTA (0.001 MB)

  • P

    Just got 14.3.A.0.761 via OTA to my Z1 Compact

  • Petter

    Just got it to Z1 Compact via OTA as well

  • Mac

    This is ridiculous..
    I haven’t found any improvements at all in this useless update. C’mon we need a bigger increase in number, even the 769 will most likely not do anything big. They better be releasing a update so we can get rid of these nasty Bluetooth problems and screen sensitivity issues. Sometimes I wish I wasn’t that impressed by Sonys features and design and bought another brand. But the others don’t even come close tho..

  • BoonerZk1

    Well?? Did it fix any bugs?? Especially the camera app related ones… With an update with this size it sure is questionable how it can improve, let alone affect the user experience on the phone.

  • MacAllan

    It’s been out for Z1C in Sweden some days now, install with PCC or update service.
    The only thing i’ve noticed about .761 is better battery time.

  • Jiyeon90

    This fixes battery drain issue, at least it did for me

    Nothing here!

  • Marlish

    its there for nexus devices :)

  • trondjac

    Great! I cant wait to try it out, its been a pain in the a** the lest month or so. I just need to charge my z1 first *sigh

  • Mac

    well the battery might have been better in 4.3 but I didn’t have my z1c so long before it got 4.4 so it’s not fair 2 say. More applications running and more needs make it drain faster. But I do not see any changes in battery from 757 to 761.

    Omg that line…

  • Emil Oskarsson

    Why do you want android 4.4.3 it’s just new phone apps and something more for nexus devices? Not anymore changes to the software itself what I’ve heard about :p you just want a new android version number right?

  • Sadman Khan

    My Z1 gets very very hot and i can’t use my phone at all when I am recharging it, because battery still drains :( Nothing like this happened before the update.

  • Bio24

    waiting that update for my Z1 compact in indonesia…. :D

  • Marlish

    Could someone please post a comment over here with detailed information about the performance and the battery life of the phone after the update like how many hours it lasts on wifi and on data probably 3G

  • prasanna

    Ur from

  • patrick

    I would prefer a big update for the camera app such as better picture treatment, raw format save support, more accurate autofocus, quicker camera start from the welcome screen…
    I have trusted in sony knowledge in this field (see RX 100 III) and I am a little disappointed.

  • Jonathan
