Xperia Z_10.5.A.0.227The Android 4.4.2 KitKat firmware update has been certified by the PTCRB for a number of Sony Xperia devices including the Xperia Z, Xperia ZL, Xperia ZR and Xperia Tablet Z. The same firmware build (10.5.A.0.227) has been certified across all devices, this is the same firmware that leaked recently for the Xperia Z, so there is no question this is KitKat. Also the date of the certification means that the firmware should be on track to launch in May 2014, which was Sony’s release date. We’ll let you know once it starts rolling.

    i want a kitkat for Xperia SP… this smartphone have a best performance gpu and processor, with the kitkat version we can have a BEST smartphone performance!

  • manutd

    I have a xperia z1 and since I’ve updaterd to kitkat,I have ruined my phone!!! no signal all the time,camera does not take more than 2 photoes,than it freeze,can’t type messages like on 4.3, lag and the phone freez almost all the time! kitkat is so stupid.how can you release such a software,and how stupid we are that we use it. my z1 with 4.3 was amazing!!!

  • manutd

    don’t do that,don’t update to kitkat.you’ll regret it!

  • TROLLZOR

    So this will be like Xperia S, when the leaked firmware with so many bugs was the FINAL first Jelly Bean firmware? That really sucks dude. Sony WTF is wrong with you?

  • manutd

    4.3 on xperia s had battery drainage problem and video camera problem!

  • Roberto Merino

    Reset your phone to factory, and all your problems will be gone.

  • TROLLZOR

    I mean S, the 2012 flagship, not the forgotten SP.

  • Mike Gonzalez

    well if you install a lot of crap-ware and update… what did you expect?

  • Reynaldi Sutrisno

    Finally the waiting time is almost over..

    Let’s just hope they made a appropriate Kitkat firmware for the older Z series.
    We don’t ask much, we just need bugfree Kitkat for our last update before being abandoned :)

    Hope for the best.

  • P9

    how can u judge dude? I’m already happy with my 4.3 which come since 4.1.2, 4.2.2..

  • Green

    What sp? What sp?

  • Ritwij

    I hope we Z users get to see versions after KitKat too. Come on, Z’s hardware ain’t that obsolete.

  • Giovanni

    sp is a best smartphone! the hardware is top!

  • Giovanni

    the xperia sp have a best hardware.. is up of the samsung s3 and the xperia z…watch antutu. Sony MUST update to 4.4!

  • xperiaDROID

    U MAD BRO?

  • Akuma

    Xperia T?

  • xperiaDROID

    Don’t worry, the Xperia T will not be forgotten, I hope.

  • xperiaDROID

    It’s about damn time, hope they got rid of all the bugs and software problems on the KitKat update. Come on Sony, I believe in you.

  • Akuma

    Lol you hope

  • xperiaDROID

    The older Z series won’t be forgotten so quickly, the processor may be outdated but it still runs like a charm, hope Sony won’t forget the older Z series, they’re the ones that helped Sony got high sales and got popular.

    Based on phonearena review for Xperia T2 Ultra Dual-Sim ~
    Xperia T2 Ultra have best battery their ever test ~
    Kudos to Sony ~

  • Mahinthan So

    But not water proof.. All I need is waterproof, 4.5-5in screen, better battery life , Hand holding ability

  • nindw

    Probably this new firmware will be full of bugs like Sony does it everytime. Yaaaay :-)

  • Anonymous

    Xperia ZR , Z1 compact or wait for the Xperia Z2 compact (Xperia A2)

  • white spirit

    that really depends on when Google will launch the next Android version.. because, if it comes after July/August, its not realistic to expect the First Z-gen to receive it, because its outside the 18 month window support.

  • Shelta

    You’re right. The Xperia Z is still the most popular smartphone from Sony. There are too many Z users out there, that’s why Sony should not forget to update them as well as the newer phones, because Z users may be the Z3 or Z4 buyers.

    Don’t wait bro…. Root it.. have Fun :)

  • shehab skull

    Downgrade it to Jb 4.3 using flash tool

  • András Csaba Sz?cs

    Are you kidding? I want KitKat for my SP too, but telling people that “SP has the best hardware” is like telling people that “the sun comes up on the west”. The Xperia SP has so many bugs including the hardware.

  • Dmitry Perets

    Hmmm… wasn’t it the build that DoomLord described as laggy…? Oh we are so happy then! =)

  • 100procentpartycrew2011/2012

    hope they have tested , but leaked fw is not like the official release , but they have have time from z1 series to test the fw to xz , :)

  • 100procentpartycrew2011/2012

    fully agree :)

  • Vitali

    Great!!! And BTW, Why the Tablet Z WI-FI doesn’t have a PTCRB page?? Just asking…

  • Adrian969

    I guess this version will add lagging and some bugs that never be fixed so we know it is time to buy a new phone. Just the way it happened with x10i and update to 2.3

  • Killian Khoo

    Nope Xperia A2 is like Japan ver of Xperia Z1 Compact ~
    Like Xperia A is like Japan ver of Xperia ZR ~

  • jhayp sevilla

    What about XV

  • XV user

    Lucky Z owners…how about XV can it still have chances to get kitkat?

    I hope the Xperia Z C6606 (T-Mobile) gets the update soon. I’m still stuck on Android 4.2.2 and I was starting to think Sony gave up on this phone, just like they gave up on the Xperia Tablet S..

    C6606 too? That’s the T-Mobile USA version… And while Z1s still yet to get the 4.4…
    But good for Xperia Z users. I have a C6606, too. been waiting.

  • John Zakaria

    Why does the Xperia Z has a few more versions that the others?

  • Robert Szombati

    Chances are low for kitkat. I’d be happy if they’d fix all the bugs in 4.3 and make the phone more stable.

  • totallymiffed@SONY

    As the owner of Xperia Z Ultra, I am pissed and disappointed – in that order – for this once great company for slipping into mediocrity. That f’head on whose watch the kitkat upgrade was tested for Sony Z phones, his/her head should roll. They were too busy giving thumbsup to their analysts and pumping sunshine up their wazoos, instead of just going through a simple pen and paper checklist of what worked and what didnt. They rushed it and now their freakin goose is cooked! I am happy to use this stupid phone as a paperweight and am a re-follower of Apple

  • cyapalmos

    I wonder if I’ll finally get to use my BT keyboard while on wifi?

  • Nawi

    Remember that Xperia ZR, Z Tablet WiFi-LTE are from May/June 2013 =)

    18 months for that models = January 2015

  • 3rdflyleaf

    I thought Xperia F is the japanese version of Z1 compact.

  • phablet

    But they had said that the build number is 10.5.A.0.230.

  • DeLorean75

    Should I be avoiding KitKat? My ZR (C5503) only has 8 GB RAM. From what I can understand, my 32 GB high speed microSD is rendered useless in KitKat, only available to save pictures and video from the camera app. Please tell me, that I’m wrong!

  • mail

    my friend recently got kitkat update for his htc butterfly…but i was so amused to see ,,,,that he stored all his movable apps to his sd card.. also he could store his fotos and videos to sd ..!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!.why is that so?,,,is that a special feature for htc? whether sony could also do this?,,,,(note: i checked myself and confirmed it and if possible i will upload a screenshot)

  • XZR User

    WE want leaked Kit Kat firmware for the Xperia ZR like Xperia Z

  • Sudesh Sush Pillay

    Keen for this update! But I’ve been waiting so long and been so excited been checking the Web everyday to see this update hahaha, my bros got the z1 and the update rocks!!!!

  • ali

    ???? ??? ??? ????? ??? ?? ???
    right ,of course You are right man

  • DaRk MaDnEsS

    the limitation is for application you install from store (if you use the application that Sony installed on android like it’s album or music or file management it should work fine )

    even in my 4.3 ,i cant move any apps to sd ,,it showed emulated when i tried using apps to sd ,,,so what the difference bet 4.3 and 4.4???????????

  • DaRk MaDnEsS

    my bad seems that Sony removed that feature in 4.3 so i think it would be removed in 4.4 also :( but i think if you root there are a lot of apps out there that can do that like AppMgr III

  • kachan64

    I’m confused. The title did say for Z series, so why need to make one if the title says it, unless…

  • xperia z

    Where is xperia z c6602

  • Bijay Behera

    C5503/C5502 both have 2GB RAM, only difference is C5502 has 4GB ROM and C5503 has 8GB ROM, the 4.4.2 update is under 600MB and what ever the future updates be they will always take installation size under 1.4GB ,there will not be any problem as you have 2GB RAM, just don’t flood the phone with games and unnecessary apps they slow the phone .

    I won’t update my Sony Xperia Z, it’s perfect like that with android 4.3 – In my opinion it’s not worth it, KitKat can’t write to external Sd Card….without that feature… customizing the phone like I do will be a nightmare that’s for sure. No thanks not for me! Btw fortunately I have Kitkat on the Htc One….and believe me there is not much difference..
