Xperia Z1_14.3.A.0.681Good news for Sony Xperia Z1 and Xperia Z1 Compact owners, it looks like Android 4.4.2 KitKat will shortly be heading to your devices. Firmware build 14.3.A.0.681 has been certified for both handsets, including the C6943 model number of the Z1 and D5503 model number of the Z1 Compact.

This is the same firmware version that we saw a leaked screenshot of recently, along with the leaked system dump. The latter confirmed that, on the Xperia Z Ultra at least, the KitKat update would NOT include a number of features seen on the Xperia Z2 such as 4K video, Timeshift video, Tap to wake, Smart call handling, Smart backlight control and Glove mode (already included in the Xperia Z1 Compact). We’ll bring you more news as we have it.

Update: All variants of the Xperia Z1 and Xperia Z Ultra have now seen the Android 4.4.2 KitKat firmware certified with build number 14.3.A.0.681.

Thanks DIMEX and Jan!

  • Maciej Damian Ga??zka

    Finally. I am waitng for “double tap to wake” for Z1/Z1 Compact. ;)

  • RealityCheck2013

    I hope most of the Z2 features come to the Z1 with KitKat :P

  • FixMax

    Of Course first month after official release 4.4 KitKat, Sony forum will be filled about getting root on that ROM.

  • z1

    Yeaaaa buddyyyy.. 1 week and we have kitkat on z1?????

  • Mohammed Khired

    y’all so stupid if you think that every Z2 feature (or at least one) will come to Z1/Z1c ,otherwise how the hell they gonna sell the Z2 ?

    (just defense mechanism , don’t get too hopeful about it or y’all gonna get some heart attack or something …like epilepsy…..shit….that’s even worse o.0 )

    LOL

  • Timbo1

    yay!!!

  • Timbo1

    They better damn it!

  • shehabskull

    I think you are wrong because my Xz with the 4.3 update is the same XZ1 in all things!
    People well buy the Xz2 because the hardware not for the software :)

  • Mohammed Khired

    buddy it’s not the same at all… -_-

    4.3 update came after xperia z1 sold widely , beside xperia z1 was too much than just software update compare to xperia z , but really not that difference between xperia z1 and z2

    so why i should get Z2 if i can get it’s features in the z1 with good price ?

  • xperiaz6603swe

    Hope the 4.4.2 include tap to wake, smart sensor, and smart calling answer machine and t9 keyboard cause htc and samsung has fix it back in the 4,4.2 update for there’s phones middle of April it gonna roll out but come on 6 month to release :$

  • karamelakimo

    wish tap to wake , gloves mode , smart backlight display , timeshift video for my Z :D

  • Maciej Damian Ga??zka

    Longer support? Rly IPS?

  • Raymond De Guzman

    Yay! This is so exciting! Hopefully it will be rolled out soon. ^^ Can’t wait for this. ^^

  • Mohammed Khired

    i repeat :

    why i should get Z2 if i can get it’s features in the z1 with good price ?

  • paul4id

    This is absurd for Sony to be holding features back from phones like the Z1 compact which have only been out for a few weeks and is essentially supposed to be flagship. What is the point in paying all that money for a flagship if it doesn’t get the flagship treatment in software?

  • Al Walid

    Mee too. The onl thing that iam waiting for and i need.

  • Karol K.

    z1 compact isn’t flagship – z1 was, now z2 is

  • ZXcorr

    This better come really soon.

  • Stephen

    the power button on my z1 takes 3 to 4 taps to wake phone up so hope this bug either gets sorted or we get the double screen tap

  • Weehaaw

    would be nice if Z got it soon too…

  • Sudarshan Rai

    Any clues on Kitkat updates for the original xperia z the time frame of update or confirmation whether Sony will give the update??

  • Clarence Alvarado

    Z Ultra will not be having 4K video due to its 8MP camera, 4K needs more than 8MP of camera to make it work.

  • victor aguilar

    so the xperia Z firmware 14.1.B.0.101 is not a mistake???

  • motze

    c6903 no firmware in ptcrb….so sad

  • AmirMohamed

    I am wondering why C6903 has no news about new firmware yet :(

  • AmirMohamed

    Yes I agree with you, but I am sure that the Z1 is more than capable of that so hope in the 4.4 update Sony gives us that

  • AmirMohamed

    I am sure we (Z1/Z1c) will not get all Z2 features but at least I will be happy if they fix the rear camera

  • Timbo1

    Its a Z1 so its included. I believe the model number that is listed in the story is the Z1s on T-Mobile in the U.S.

  • motze

    no… i have c6903 in europe….(Romania)

  • paul4id

    Sony’s marketing of the Z1 compact contradicts everything you say. Most people don’t value humongous phones. To me Z1 Compact > Z1.

  • SinaKing

    Glove mode isn’t a software feature !
    Device screen panel should have this capability !

  • paul4id

    Well, it doesn’t look like we are going to get it so we need to complain. Personally, I think smart back light control is more useful, and is something that has been on Samsung devices for 2 years now.

  • hocestquisumus

    It’s the same hardware, only smaller.

  • SinaKing

    C’mon man !
    Z2 have many special hardware features ( for example Stereo speakers , Glove mode support , thiner with less bezzels , Biger panel , Better panel/Ips with live colors & better hardware specifications ) .
    You can’t tell that i’m going to have all/some of this hardware features on z1 with a kit-kat update !
    I have z1 for now & i will sell my z1 soon & get a z2 !
    Not because of z1 isn’t good ,
    Because z2 is a perfection !

  • Blaven

    Of course. Phone comes with an outdated system to start. Later, after a long delay I get it, but without the function that should be there. Finally, the new model has to be something different. Recording in 4K is supported by Snapdragon 800-AA, and the LG G2 has it …

  • Nidou

    Where is the Xperia Z kitkat update?

  • gtop

    But the Z1 Compact already has Glove Mode on 4.3 … so in this respect at least there must be some differences in the implementation of the new firmware, even if it’s the same as the Z Ultra’s. Presumably?

  • RHBH

    Don’t worry guys, I have a C6943, if by any reason I get it before the other models I’ll sent the files for you… But no update until now :P

    http://forum.xda-developers.com/showpost.php?p=51194460&postcount=1460

  • HardyHarHar

    It’s not… Battery is different(smaller), body is different(smaller), digitizer is different(has pressure sensor) & screen is different(it’s an IPS display not like the z1’s old tft display). How can you even tell they’re the same?

  • HardyHarHar

    Alot of samsung fanboys can answer your question there buddy. Why not ask them why they bought the s4 when they can get the s3 with all s4 features with a good price?

  • HardyHarHar

    T9 english keyboard exists in the chinese keyboard :p Learn to explore it haha!

  • jag

    The phone that would benefit most of that feature is the Ultra.. So why they did not include it????! Argh!!

  • oB

    Not before Z2 launch, but after it’s available to all, some of its features will probably be added to a new KitKat firmware later on.

  • Mohammed Khired

    Well, other than the stereo speakers and the ips panel, nothing really can make me leave my z1

    If you gonna sell your z1 and buy Z2, THEN WHAT THE HELL YOU DOING HERE?!!

    Beside I don’t have time to sell this and buy that phone…

  • Mohammed Khired

    Do you really think before you write or you just fart words out of your ass?

    Congratulations, you got my attention

    I hope you enjoy your loneness..

    -_-

  • starkiller306

    so according to you it’s better than the Z1 but not a flagship? i mean apart from the smaller battery which in fact is actually better even though it’s smaller…

  • starkiller306

    so according to you it’s better than the Z1 but not a flagship? i mean apart from the smaller battery which in fact is actually better even though it’s smaller…

  • Tom Nguyen

    youre so wrong its not a hardware problem ! if sony doing this way i dont think z1/z1s user will buy new xperia phone from sony ! just get sam or htc and get all new features

  • Red Tea Elaine

    ??????????4.3????4.4?

  • Vincentius Phang

    please include +700mah battery and +1gb RAM
    but yeah, your point makes sense
    but lets hope everything software-wise will be ported :)

    Xperia SP T/V/TX the tainted software bugged phones!!
    XPERIA Z series always lucky series lol

  • HardyHarHar

    tap 2 wake & slow motion video has been implemented already on different devices like samsung and HTC. I don’t understand why sony would keep it of Z1 and Compact users. I mean it’s not an exclusive or rare feature anymore.

  • HardyHarHar

    typo errors >.< *off

    so Xperia Z1 won’t get 4K video, Timeshift video, Tap to wake, Smart call handling, Smart backlight control and Glove mode?same as the Xperia Z Ultra?

  • Muhammed dAli

    Are you retarded?! The hell does sending software stuff in the Z2 to the Z1 going to affect sales? People will still buy the Z2 regardless, it has a new design, improved Snapdragon, better screen. Sending software from Z2 to the Z1 won’t affect sales, people who want the phone will still get it regardless if the Z1 can do some of the things the Z2 can. Because if that was the case then why should any manufacturer bother with upgrading to newer versions of android.

  • Gaj

    I think a camera flash would most benefit the Ultra

  • KeepCalm

    You need to have a tall glass of, “Calm the Fuck Down.”

  • ash

    The most important thing I want is better ram management. Less ram utilization. And whatsoever google gave us in kitkat. I already have glove mode in my z1 compact. Also need some camera feature. Rest all is ok.

  • Z1ZLIndia

    Answering Machine ! please

  • kater

    I think maybe the second 4.4 update would got these elements, sony need sales on Z2, isn’t it?

  • kater

    damn it, any news for ZR, please?

  • Grrrrrrrrr

    Only the Xperia Z Ultra will NOT get the toys from the Z2,read the post slowly.

  • laci_csk

    How do you think a compact or mini to be a flagship?

  • Night of Xperia Z

    I also waiting for that.
    Yestarday saw Xperia Z Ultra Kitkat firmware. Today see Z1. I think our Z is coming soon
    :D

  • ??????? ?????????

    Still no update for Xperia SP :c

  • Sagad Mopa

    “People will still buy the Z2 regardless, it has a new design, improved Snapdragon, better screen.”
    If I already have z1, then no. Im not gonna buy Z2. Gonna wait for Z3 instead.

  • Chill out guys. Z1 already has a hardware that can support almost all those features from Z2. Lets see which features from Z2 the new Kitkat Update brings on the plate and we will port all the remaining ones which it doesn’t. ;)

  • DaX

    Xperia z1 is getting it,ultra is not.Learn to read.

  • xperiaz6603swe

    I don’t think so:-D

  • josesl16

    Then don’t.

    That’s your choice, but not everyone is going to say “nothing can really make me leave my Z1!!” when they don’t really have Z1 in the first place and also are changing from other phones. Those hardware improvements(that SinaKing mentioned) that you somehow want to ignore so much may as well be a deal-breaker for people looking for a new Sony smartphone, in between choosing to buy between Z1 and Z2, not to mention people who wants to keep up with the latest and the greatest, even if that would cost them more bucks.

    And then there’s also that Sony isn’t necesarily aiming this towards people who had the Z1 only, but also people who are looking to buy a new phone from older handsets or from other brands.

  • sonyc

    the KitKat update would NOT include a number of features seen on the Xperia Z2 such as 4K video, Timeshift video, Tap to wake, Smart call handling, Smart backlight control and Glove mode………CAN’T YOU READ PEOPLE!! THERE WILL BE NO 4K RECORDING NOR TOUCH TO WAKE.

  • blckaapl

    Get the LG G2 then. Lol. >.<
    I've had that before and its not that responsive. Hopefully Xperia is!

  • Nidou

    yeah I hope It’ll be soon! :D

  • Sebastián Andrés Vivanco Zeped

    Tap to wake isn’t include in the Z1

  • Olav Alexander Mjelde

    Yeah, most of the camera related features should be doable, if not all.
    The Z1 and Z2 feature the same sensor and lens, so maybe just the most demanding features might be limited to the Z2. Or maybe not :) Depends on the current overhead.

    I havent tried sideloading the apps that have been leaked.

  • Zoidbort

    So this “All variants of the Xperia Z1 and Xperia Z Ultra have now seen the Android 4.4.2 KitKat firmware certified with build number 14.3.A.0.681.:” means it includes the 32GB Japanese KDDI SOL23 Z1 version?
    I SIM unlocked the SOL23 I bought and I am running the Generic International FTF (C6903_14.1.G.1.534_1277-2880_R4A) that I just updated to 4.3 (and somehow lost my SMS unless I make a phone call 1st) however this FTF does not see the on board 32GB of storage as this model is the only one that has it.
    So if the 14.3.A.0.681 is good for all, I wonder if they enabled it to recognize the 32GB now?

  • jag

    not so… doesn’t even use it. but to others, yeah maybe. so they can shut up and quit their complaining.

  • Marcin Podsiad?y

    Z1 compact has plastic back so it’s different, it has worse 720p display instead of 1080p in Z1 so it’s different.

  • Marcin Podsiad?y

    We are waiting for 4k video and timeshift video for z1! Yeey! :) :) :) anything about game performance?

    i have the kitkat official update flashed it last night on my xperia z1 using flashtools. its the official xperia rom with the same version number 14.3.A.0.681 and it runs very smooth indeed love it. cant wait to get the z2 but a much improved z1 thats lightning quick camera is fantastic. if you want the fimware file google C6903_14.3.A.0.681_Generic Fr.ftf dont let the fr put you off its unbranded and in english. flash and enjoy your new rom

  • Marcin Podsiad?y

    Now my Antutu score is much worse on 4.4 :(((
    Even below G2…
    Something messed up.

  • giri1in

    Z1/ Z1C users WILL eventually get most Z2 software features, BUT after 2-3 Months……HOW can we say that? Well, the .APKs of the SlowMotion, Camera Apps, etc are working on rooted Xperia Z1 and Z1c….Sony has made them reasonably compatible to Z1……..hence sony will not keep them away from the users for a very long time…..
