Xperia Z firmware_10.5.1.A.0.283We recently speculated whether the recently certified firmware build number 10.5.1.A.0.283 for the older Xperia Z series would bring Android 4.4.4 KitKat. Well judging by the leaked screenshot below it appears to be true. It shows the Xperia Z (C6603) handset running Android 4.4.4 via build number 10.5.1.A.0.283. The update is expected to land on the Xperia Z, ZL, ZR and Tablet Z. We’ll bring you news once it starts to roll.

    Hope so this brings the ‘real KitKat’ to my Z

  • Constantine

    No 4.4.4 and app2sd on Z2. Very nice. Sometimes it seems that my Z2 is not flagship at all.

  • AndropaX

    Editing build.prop is not dificult…

    anybody knows how to decrease volume when i’m calling ? After updating my XZ to 4.4.2 it’s too loud even on lowest level… Sorry for my bad english

  • Fapples Christos Karadimas

    z2 is the real flagship dont worry

  • XperiaSP

    Xperia SP? Oh, come on sony

  • Constantine

    You can forget about 4.4.4 on SP

  • XperiaSPuser

    Install CM11 and stop to complain on every post.

  • Rick N

    why not skip to android L later instead, XZ is 2013 flagship i hope still get android L

  • alaka

    Wat of Xperia M is kikat available for it

  • grav1ty

    don’t be a daydreamer dude

  • lol

    That OLD phone will NOT get it, so bye bye :)

  • Rick N

    i have xperia V also it’s early 2012 and still got 4.3 few months ago. If samsung still gives update for early flagship like S3 or S4 why sony not. Sony produce variant too much in a year

  • Sam Albalushi

    Just fix battery drain and overheating

  • Guest

    They probably move 4.4.2 from to L, skipping 4.4.4 on Z2.

  • David Hvatov

    They probably move from 4.4.2 to L, skipping 4.4.4 on Z2.

  • Constantine

    Z2 will get L in october or later…

  • DaRk MaDnEsS

    Did s3 get kitkat? And s4 is newer than z

  • Nawi

    S4 will get Android L
    HTC one will get Android L
    Nexus 4 will get Android L

    I’m with you. Why Xperia Z not? =)

  • BrookG

    I would be happy if they just fixed the battery issue.

  • sovpanda

    S3 got kitkat besides t999 version (no one knows why) and the international that had to lil ram

  • Peter

    It won’t. Support ends next month – unfortunately this is official.

  • AsadMulla

    I think its because they need to sort out battery issue on XZ now so they updated it to 4.4.4 where as XZ2 doesnt seem to suffer the same problem

  • Riyal

    S4 = Snapdragon 600
    HTC One = Snapdragon 600
    Nexus 4 = It’s a google phone running vanilla android without bloat

    Thing is I don’t think S4 pro is capable of running smooth android L. Unless of course you choose to go vanilla like Nexus 4 which I’m sure will also happen once FreeXperia ports Android L to Xperia Z…

  • Riyal

    lol! Why is it that every article I open on Xperia blog I see users of this old mid range phone always asking for updates? And even when Sony releases an update for this phone a few days after I again see them asking more updates? I dunno but is this the god of all phones that it should receive a new update everytime a different model gets one? Why is it that Xperia SP has alot of update whore users?

  • NKD

    You can’t ever understand the fact small buddy…that xperia sp is the best mid range phone from sony till date…see its specs!! Its a beast of mid range smart phones!! But since 4.3… Sony has just started to illtrear this phone regarding updates!! Updates wid bugs nd bloats!! Nd sony promised android kitkat for this device earlier and now its under investigation!! Xperia sp deserves a lot more than what sony is feeding it in the present time!! Daz why we are asking for atleast a bug free software of 4.3 aur totally a brand new firmware kitkat which was already the future version for this phone on sony’s website!! Which could bring the pride back to this phone agin!! You got it?? No??!! Read this comment of mine again chote bachche :D

  • Riyal

    Whether it is the best phone in history you can’t deny the fact that it’s “old” if you read the manual included in your phone it states there than sony will provide updates for their phones for 18 months. And Xperia SP was launched March 2013 which will have it’s due on september 2014. There’s no such thing as a bug free OS. AFAIK microsoft has been developing windows for decades already yet it’s still full of bugs. What more can a measly company like sony do compared to a tech giant like microsoft in comparison? In fact Sony doesn’t even own android. Google owns it hence they literally can’t control the core bugs.

    Sony is running a business here there’s no profit in supporting old phones forever and they need to move on. If you don’t believe me try making your own mobile company, release a model and promise lifetime support to it. The only thing they can do is give decent updates on their products and that’s it.

  • Ninjas

    this is sony’s fault by over promoting xp sp in the first place. It now turn to diseases

  • Nawi

    S4 pro (Quad Core 1.5GHz & GPU Adreno 320) with 2GB RAM is not capable of running Android L, and *Snapdragon 200 (Dual Core 1.2GHz & GPU Adreno 302) with 1GB RAM yes? :/

    *Moto E

  • xConjo

    Moto E doesn’t have the same performance as the Xperia Z

  • Riyal

    Moto is almost vanilla android… Also we’re talking about flagships here… If a flagship phone runs slow then it’s a big slap for Sony… Remember the ICS update on the Xperia 2011 devices? If you own one that time.

    Also on a marketing standpoint companies such as sony need to do this in order to gain profit. They won’t earn anything if they keep supporting Xperia Z but will earn millions if the discontinue support of an old flagship and release a new one. This is different from google which earns profit just by you using it’s google services like playstore etc. And Motorola is owned by google.

  • Nawi

    You’re right!. Moto E gaming performance is very poor (and with 540 x 960 pixels display!)

  • Nawi


  • C6602

    This update is for C6603, how about my C6602? Can I also receive the update?

  • wim den boer

    Hopefully my xperia zr is finally getting kitkat, haven’t got it in Holland so far

  • Chan Kin Cheung

    you can flash .230 FTF, even pre-rooted version,

  • Chan Kin Cheung

    i totally agree with you. A “leaked” picture is not convincing enough to prove anything, let alone a capped screenshot.

  • xperiaz2tablet

    dont need to worry about it. Z2 will probably be the first one to get Android L

  • StopXperiaSPusers

    omg i’m laughing so hard lmaooo

  • Constantine

    There are plenty of other problems on Z2, and no bug fixes expected.

    FYI, Google designed Android KitKat(Vanilla UI) to work on phones with just 512MB ram, in theory the GS3 international version was supposed to be no problem because it had 1GB RAM, but due to the heaviness of the new TouchWiz UI, Samsung cancelled it later.
    The US version of GS3 had 2GB of RAM, it has no problem with the new TouchWiz UI to work, that’s why the GS3 US version is getting Android KitKat.

    chill out guys it’s not like armageddon hit the earth or something, why everybody (and comment below) so serious. Well if the update based on “the release date” not “the spec” since lower spec like C series or T series. Logically Z, Z1, Z2, Z3 are considered the same it shouldn’t hard for sony (and also 1 year FOR ME is considered pretty new)

    I dont know if you have experienced the battery drain issue on xperia Z but I am sure many on this blog would agree with me its a really big problem. I talking 100% to 0 in a matter of hours while barely even using the phone.

    My Xperia Z has build number 10.4.1.B.0.101 and my customization version is 1275-8863_R1c

    I still haven’t received Kit Kat and I don’t know whether I will ever receive the update for my phone. Can anyone help me out so as to find out when I will get Kit Kat to my phone as its still stuck on 4.3. I’ve tried update through PC Companion but it always says my phone is upto date…

  • CENA

    Buddy.Shut the f*** up.Stop saying OLD.Go and see Antutu benchmark results.XSP completely destroys XZ,dumbo.

    apple give support for 4-5 year and nexus also (i know people will say “android 1.0 better than ios 8”) so your argument “there’s no profit in supporting old models” is invalid

  • dimz

    Because Sony gave it specs that are a little lower than their then flagship of their 1H 2013 line, the Z, they claimed it would be upgraded up until 4.4, and a few months later started trying to persuade people to switch to what are essentially downgrades in terms of specs and hardware.

    It’s old, yes, but they are using cheap tricks to evade working on stuff they could reuse, just so they can escape the obligatory 18 month support limitation because support doesn’t pay them extra.

  • Kunal Shukla


    Sony official statement from sony support forum…Update is definitely coming

  • Babak

    If you want a real bug-free OS, you should try HTC ONE.

  • rubinash

    Apple only gives three years of support… Considering that the iPhone 3GS launched with iOS 3 and got until iOS 6, the 4 launched with 4 and got until 7, and the 4S launched with 5 and will apparently get his last major update this year with 8.

  • Moehamad Pay

    why in my Xperia ZL no notice of the existence of kitkat 4.4.2 software update?
    work on PC companion was not there? and I still use a jelly bean ,,
    how this could happen? #From Indonesia

  • john

    pls sony u guyz should keep supporting z till 2015 may tho z1,z2,and z3 are out but in african countries the z just became relatively affordable i just bought my z last week and am sooo sad u guys might not update it to 4.4.5 or android l soo love this for just keep supporting sony xperia z and for all those complaining commo they gave v update to 4.3 thats really nice soo love sony

  • victoria
