Xperia Z2_23.0.1.A.3.9A new firmware version with build number 23.0.1.A.3.9 has been certified by the PTCRB for the Xperia Z2 and Xperia Z2 Tablet. Sony Xperia Z2 owners have been patiently waiting for the Android 4.4.4 KitKat release – this new software marks the second certification of Android 4.4.4 firmware for these devices.

The first certification with build number 23.0.1.A.0.167 has not been released so far. What we don’t know at this stage is whether the ‘167’ firmware is still destined to roll or whether this new update supersedes it. We’ll keep you updated.

    Well how about that. Another certified firmware but still no release. For myself I’m happy with 4.2.2 because it works like a charm for me and I rather wait for Lollipop to be released in early 2015

  • Angels

    But if theres is onother one frimware certified, then wen will be the releas of it? There is no spesific date of it.

  • Angels

    And when 4.4.4 will be available on xperia z2?

  • demize

    2015

    Good to see Sony is working on it, so it would be without bugs after the release… I personally am happy with 4.4.2, but I understand the need of having 4.4.4. (required for fully working with PS4 Remote Play) and of course, to have all features of Z3 is also appreciated. :)

  • Arthur Simon

    I hope they bring the manual mode improvements from the Z3.

  • Amirullah Izham

    They have support hi-res ? Just ask here.

  • Sonny

    Soon expected before end of year

  • David Hvatov

    Hi-Res is already in Z2, but there’s no DSEE HX at the moment.

  • Certainly it is a Vodafone ROM , note that the D6502 model has not been certified

  • Ritwij

    How do you have 4.2.2 on Z2?

  • Michael Paul Granberg

    Sorry about that. Of course it should be 4.4.2 and nothing else

  • Faisal Armand

    Where?

  • David Hvatov

    In audio settings you can enable hi-res via USB. It’s same, like in Z3.

  • ShinOrochiX

    *Correction, 2015 as said above.

  • Arthur Simon

    Hell no. 4.4.4 will come already in November I’m sure of it. Lollipop will come in 2015

  • XperiaZ2

    I hope they fix the camera to stop refocusing every time the shutter key is pressed. So annoying especially when the frame is already focused!

  • guest

    Certified? Again? That’s proof my regretion in buying Sony products. But what bugs me is that most of word wide 2013 flagship are on 4.4.4

  • I’m thinking they may have come across some bugs on the last certification, and pushed a new one that’s been fixed up. The amount of people complaining that they don’t have 4.4.4 would triple with people complaining they upgraded to a buggy OS.

    I somewhat agree that a lollipop release at this point would be satisfactory, however that would mean no updates until February 2015, which also would likely mean no remote play until then.

  • BruceLeeRoyJenkins

    How long do we need to wait for a firmware or update that solves the Baidu issue?

  • roeshak

    When has Sony ever released firmware without bugs. Forget Sony, neither has anyone else for that matter. The best case is not to have any serious bugs and to keep little ones to a minimum.

  • berkay

    i’m sick of saying this, it is better to wait on a stable release than having a buggy one.

  • Angels

    early 2015 will be 5.0 android.

  • Angels

    in november or december?

  • Fadi Obaya

    What the fuck is your problem?

  • Dean

    Why I love owning a Z2 over a Z3: sexier design, better battery life, better speakers (at least according to gsmarena), I can overclock it to 2.5GHz just like Z3, I got to own it earlier and best of all: I get basically all the Z3 new features either officially or ported.

  • hansip

    And yet xperia z3v is criticized for its z2 body.

  • Kunal Shukla

    why not update directly to 5.0

  • Ritwij

    Off topic: I’m an Xperia Z user right now. Should I upgrade to Z2 or Z3? I don’t really see a big difference in them, but Z3 is a lot costlier. Z2 has a better speaker and slightly bigger battery and better battery backup. Z3 has a better body, slightly higher clock and obviously is newer and the current flagship. I’m way too confused. Though, I have a third option- wait for Z4. Help me. :/

  • Boonerski

    Wait for the Z4 IMO. I think it may come with a 64-bit chipset with Lollipop out of box. That’ll surely be a larger upgrade than the Z2/3.

  • Simos Katsiaris

    simple, don;t use any chinese or asian software

  • Simos Katsiaris

    they need the source that will be available on december or early october, also on 4.4.4 they will give as back app2sd that they have to since they promised and sony tries to keep the promises since erricson used to always break them and almost killed the mobile division

  • Simos Katsiaris

    that is for lollipop, it’s this month around 15

  • Kunal Shukla

    app2sd are you kidding me and I think they already have the source because the final version has already been released to developers

  • RoberMC

    International factory unlocked model is D6503, and this firmware has been certified for it.

    scrolling contact list won’t be creamy anyway, multiple cores, many gigahertz, and still hiccups, ridiculous

  • Some providers have pushed out the 23.0.1.A.0.167 release. As mentioned, it may be that it’s got a few bugs, and most will wait and then bump directly to 23.0.1.A.3.9
