in Firmware, Sony Tablet, Xperia Z and Xperia ZL, Xperia ZR

Xperia Z_10.5.A.0.233Sony will shortly push out firmware build 10.5.A.0.233 to the older Xperia Z series including the Xperia Z, Xperia ZL, Xperia ZR and Xperia Tablet Z. This new build follows on from the first Android 4.4.2 KitKat release (10.5.A.0.230) for these models and is likely to be a bug-fix release.

We already saw Sony’s workaround on the battery drain issues this morning, but hopefully the new update will go further to provide a more stable KitKat experience. We’ll let you know once the update starts to roll.

Xperia Z firmware build 10.5.A.0.233 certified for C6602, C6603 variants

Xperia Z_10.5.A.0.233

Xperia ZL firmware build 10.5.A.0.233 certified for C6502, C6503, C6506 variants

Xperia ZR firmware build 10.5.A.0.233 certified for C5502, C5503 variants

Xperia ZR_10.5.A.0.233

Xperia Tablet Z firmware build 10.5.A.0.233 certified for SGP321, SGP341, SGP351 variants

    Indian shores are far away in case of any updates… Even after the launch am sure this update too gonna take weeks of waiting i.e it is a long wait for kitkat for ZR in India.

  • Rahul

    you don’t get update on phones so soon.. but on Sony pc companion it is always available.

    You people complain as if the phone even has problems on 4.3
    The phone is fine and works great. Do you know how many people are completely satisfied with there phone and don’t even realize they can be updated Lol.
    I run into people using phone’s that have like 4.2 or 4.1 and they updates available but don’t care.
    Cause the phone works ^_^

  • Sumo

    Does that include other Sony products like their headphones? Wait, you mean headphones have firmware updates?! Now that’s new! I guess you won’t buy that too huh? Because it won’t be ‘stable’?

  • Sumo

    I hope the battery problem get’s a fix. My X is still a great phone, but ever since it ‘mated’ with our beloved Kitkat it has been sucking it’s juices fast. Just imagine if your balls run out of juices and you can’t shoot anything! That’s how I feel for my X at the moment…. it hurts to see it like this dammit! So Sony please fix this problem with this update!

  • Karan Chaudhary

    fu ck u sony…..
    s4 got fucking update in may nd u guys are just shit…..u can’t even gives us a update why are u selling phones….go nd start making some shit….

  • grav1ty

    Still dont understand why carrier devices get higher priority when it comes to roll out ? My XZ is unbranded, generic, non carrier device but in Germany, Vodafone and T-Mobile devices already got that update 1 week ago.. Normally generic devices should get it first, that’s why i always chose non carrier devices.. But hey, we all know that Sony is very strange when it comes to updates.. And NO, we wont get .233 directly, that’s just a fairy tail

  • Reynaldi Sutrisno

    Personally I don’t care so much about the updates because my SP is working fine in 4.3
    If the update was kitkat, then I will moan everyday :p

  • Killian Khoo

    u can check it on xperia update checker on PC app ~
    Current US , China and Thaiwan got it ~

  • chandrasekar

    still we not received for. 230 and now again we have to wait for. 233

  • Quique García

    I haven’t gone through any lag issue, or at least I think so.

  • Billy de Fretes

    I shouldn’t upgrade my 4.3 to 4.4.2, my xperia Z lag, battery drain so fast T_T

  • David T

    Spot on!

  • xperiaDROID

    There’s nothing wrong with the Android KitKat update on my Xperia Z, I didn’t notice any bad battery drain, it’s just the settings menu is a bit laggy when scrolling. But I hope this new update will improve more, because I noticed that when my phone is booting up, it doesn’t have the PS4 sound like on the Xperia Z2, and it doesn’t have the “Powered by Android” text on the boot up screen, so I hope Sony will add these things and improve the speed of the phone and give us a perfect experience.

  • Dissappointed

    meanwhile generic malaysia firmware still stuck on on 10.4.B.0.569 which is 4.3,that suck

  • xol3gram

    I have another problem : power button does not work anymore to end a phone call. The fact is it works but only if I put the phone out from my ear. It seems the sensor which turns off the screen disables the function. I remember it was the same problem with the last update of Jelly Bean and Sony released an update which fixed the problem. I hope Sony will do the same with KitKat, please Sony dont forget it because It’s a very useful function !

  • sakai

    I hope this 233 update can be perfect…sony pls dont let us disappointed again!becos I wait the kitkat version long time alredy!thank

    yes all other countries already got the update but still no update in india….

    I’m not completely sure what your talking about. Assuming you mean battery bug in 4.4.2? I had that issue but just turned Google now off and fixed it. Seems a bug fix just got through as well.
    It you weren’t talking about that I don’t know what other bug is.

    so for those who whinig about updates , if you really that junkie about getting updates on your phones often, go ahead and install cyanogenmod 11 and than you can set it up for receiving daily updates so your problems will be solved sooner or later.

    as for sony firmware it’s not only google services draining battery, but also all kind of so called enhancements from sony.

    simple small apps or media server or stuff you call throw is hidden in system and running in background all the time, draining your precious juice even in standby.

    my xperia z on sony firmware goes from 100% to about 60% in 3 hours – and im not even using my phone alot, and no my sync and location settings are not on all the time.

    meantime on kitkat from cyanogenmod ver. 11 i have 100% to roughly 48-45% at the end of the day, so still some juice left for nightime browsing.

    hope i helped someone here

    That’s just plain stupid. You admit yourself that headphones don’t have firmware updates and then say your anger is directed towards all Sony products. What sense does that make?

  • abc150781

    I don’t guess so. In my opinion we will get .233 directly.
    Or is anybody think different?

  • Sandhu

    I say that because i am very disappointed from update service….. I said nothing about headphones or something….. That is my anger with Sony because i am facing problem because of sony service…. Then What is wrong with you….there is nothing related to you……

  • Sandhu

    Lets see…..but i think that we will first get. 230 then. 233…..because. 233 is Bug free update for 230 so…….

    we will get the .233 update first bcz same was the case with Z Ultra..The Bug Fix update was first released in India and Later in Other countries

    After update to 4.4.2 the battery charge leak as a beer from bottle. Recommended by Sony acts with Google Play Service app not work! Fuck! Fix it immediately! I’m sorry but it’s not good work. And more: why made backups on 4.3 is not for using? Or they made on Windows Phone???

    No frd only 12 days….i got 4.3 in few days and now 25 days still no kitkat….

  • I can’t believe there aren’t any updates for the SGP312 variant! (I’m on 4.3, compilation 10.4.1.B.0.109.) I love my Xperia Tablet Z, but it is ridiculous that they didn’t update all variants for the same devices.

  • Nibbler

    Sony roll out 230 without testing it. They find the time to announce and do the PR for a patch called 233. 2 weeks on and no sign of it on their servers or anywhere. Once its ready for rollout and ready for announcement and considering how much trouble the previous poorly tested update caused, you’d think they would be all over it.
    Time to root it, and next phone wont be from a non-tech firm like this.
    I pmsl at the comments like “Just turn off all the useful features of that expensive phone then it might not drain the battery”. For 1, this approach doesnt save the battery very much, 2 – if I wanted a cheap phone without useful functionality I wouldve bought one.
    Stick to DVD players Sony, it’s more you.

  • cyapalmos

    Anyone seen anything on the tablet z yet? I checked today via PCC and SUS and nothing.

  • Alex

    The reason why your not getting the update is because Sony wants to test it before they release it. In the north american version, they did not test it and released it which caused a major battery drain in most models. I did not suffer from this battery drain, but most did. Sony warned customers not to update until google play services 5 comes out. It came out a week ago her in north America, and most battery problems were resolved. Now all Sony needs to wait for is Google play services 5 to be available on your country so they can release it.

    If you are not getting your update but friends are near you, its either that your network doesn’t support the update yet or you have a fake Sony xperia z.

    I’m sure you’ll get the update.

    Why would you all on a thread which is about the .233 update?

  • Emma

    That’s fine not to upgrade the software on your phone providing one doesn’t download an app that requires the update in order to work properly! Bravo to those who don’t have problems because they have not updated and got old software…..but the rest of us want to enjoy the latest apps etc and have to update and get cross when that same update throws the phone into meltdown! By that I mean constantly having to reboot and even hard reset on occasion, and turn phone on and off just to stop it from getting so hot it burns one ears off and I’ve even heard of screens cracking because of it ……luckily mine hasn’t yet, only because it spends more time off then on, allowing it to cool down. It is Google Services that is the problem and can go from 6% to 88% in a matter of mins causing the overheating problem! Roll on the update to fix the last update and you can bet your life that update will also require an update to fix that too! I’d laugh if I wasn’t too busy crying…..sob….!
