by XB on 26th February 2014

in Firmware, Xperia T, Xperia V

wpid-screenshot_2014-02-26-22-42-52.jpgJust a quick heads up to let Xperia T (LT30p) and Xperia V (LT25i) owners know that a new bug fixing update is also heading to your handsets with build number 9.2.A.1.199. This follows on from the 9.2.A.0.295 update which brought the first Android 4.3 Jelly Bean build to these handsets. We’ll keep you posted with any further developments.



  • Yolo

    While I’ve not even seen the first 4.3 in the UK :(

  • AhhdafunK

    An update for T and V ? :O impossible Praise the Helix Fossil

  • lon

    finally, there so many bugs in my xperia v 4.3 i hope this update fix all the bugs.

  • TradersF

    Me too. My video camera sucks bigtime. I hope this fixes it!

  • TradersF

    How could you not have it by now! I’m in Australia where the Xperia V was not even released and i have it! I bought my Xperia V in Sweden if you’re wondering. Try PC Companion!

  • Jesuspi

    Same here, no 4.3 yet. UK unlocked, customisation number 1266-0471. And here I thought that buying an unlocked device meant getting updates from the manufacturer as soon as they were made available without the extra delays of carriers.

    Not going “XPERIA OWNER SMASH!” over it, just miffed and disappointed though.

    Let’s just hope that the 4.3 update doesn’t turn into a play by Samuel Beckett.

  • skeleton

    hope they update flickering bug

  • Jerry Berglund

    Many bugs? I only have 3-4 bugs… and then the camerabug is the most bad one.

  • Lukas

    Wohoo Release the sources also Sony =)
    Oh and 4.4 … Wahaha just kidding (*>.<*)

  • Martin Ambre

    good to know

  • scw

    The flickering bug is the most annoying on my V but I do not see the bug with the camera.

  • kaostheory

    Just got 4.3 for Canadian T yesterday. Don’t know about any bugs.

  • XV user

    Good news..hope with this update will fix some bugs on my V especially the bugs occur when i want to change the themes…:)))

  • Vimu

    Please Sony, release Android 4.4 Kitkat update for Xperia T, TX, V.

  • Vimu

    yeahh Xperia T also have that problem.

  • walker

    Even this news appears, I still on 4.1.2 :D

  • mmmmmmm

    Didn’t complaint before..Xperia L 4.3??? :/

  • Leo

    TX’s fully-chagred power-off bug. T also?

  • xperia fan

    Looks like a slightly large update there…i assume this is the last update of 4.3..:)))

  • well done sony (y) release date? :D

  • xperiaV

    Posting the official page for xperia v forum on sony worked, all people having issues went over there XD
    Hope this update makes xperia v a beast without bugs :3
    Type xperia v talk sony for the official forum

  • Dmitry Perets

    And maybe you are right. Because even if 4.3 becomes stable and bug-free, I can’t start liking some of the UI changes. Walkman, Calendar, wallpapers, folders on the homescreen, some other minor elements – all those were IMHO better on 4.1.2. “Don’t fix what is not broken” – this should be the principle. So far it is “changing just for the change”…

    That being said, I do like some other changes… so it is hard to decide to go back, once this update is available… but making it stable is a must!

  • Dmitry Perets

    WHAT exactly do you expect from 4.4 update?

  • Cezary Raczy?ski

    No 4.3 for Xperia T from T-Mobile Poland :-( :-(

  • mand

    More than two bugs consider many! haha lol

  • vguj, fghh

    Last update for XT XV…. I guess

  • Xperia user

    last update of 4.3 jelly bean because these phones will get kitkat after this….:p

  • Jerry Berglund

    Hehe. Ok. For me I think 5… mostly. But ok, its mostly about how bad the bug is as well. The camera bug is bad. Really bad. But the other bug I have I dont feel like its a real problem and can accept it. So for me I only HAVE two bugs that I think is critic, but the third and fourth is something I can live with. lol

  • laci_csk

    Agree with You.

  • Tomaz Habulin

    I didn’t even get 4.3 in Slovenia yet! Mobitel Slovenia keeps us waiting..

  • doud

    i didn’t even get the first 4.3 in france. Hope this one will fix all the issues.

  • jhayp sevilla

    Cant wait for my xperia v to be bug free

  • Karel Komjathy

    You wait the next 4.3 firmware, but this current fw is bad :(

  • Io

    Just a big “up yours” to all who cried that Sony is refining the .295 update for the last 3 months and this is the reason why they delayed so much.

    Coming back to the bugs of the 4.3 update, besides the ones already mentioned here I would add also the Contact App which is not allowing to edit existing contacts, just crashes when you try to do that, the in-call picture is now covered by the tab with the phone number and timer on the top side, not showing the type of the phone number for that person (if you have more numbers for the same person, labeled work, mobile, home, etc. just showing the number itself now), random reboots which were not existing in 4.1.2, changing to downloaded themes enters into continuous reboot loop due to the sim pin request, notification light color cannot be changed anymore for notifications like e-mail, sms, calendar looks like crap now, the old themes/wallpapers which were nicer disappeared.

    I would say that there are enough bugs in this update so it can be categorized as a rushed and unpolished update, which is embarassing for the ~3 months of delay from the initial announced launch. Lame.

  • timi

    What flicker?

  • Flashtool is you best friend.

  • weknowwhytheydelay

    It’s not lame at all..the reason for the delay is prize assholes like Micro and xperiaDroid needed time to put the bugs in to make us all buy a Z series phone. “If the delay didn’t make you upgrade, then the bugs will” is their motto! Expect the bug update to also be delayed and full of additional bugs!

  • yodo

    Relax, should be another month now.

  • kitkatforT


  • godot

    I’m here…but where’s our Dec 2013 update?!

  • whynot4.4

    better RAM management, will be pretty handy when the phone gets a bit older

  • alwayslate

    hopefully by mid march, sony is just 100 days late. Sony Standard Time

  • Dmitry Perets

    And why are you sure that RAM management optimization of the core Android 4.4 will have a positive effect on custom Sony software if it will be released for Xperia V?

    Do you feel the better RAM management with 4.3 comparing to 4.1.2, specifically on your Xperia V? Becuase you know, Android 4.3 is more optimized than 4.1.2… theoretically speaking.

  • abbood

    after 4.3 my tx turn off when battery charge is 4%
    any one have this problem??

  • Mr Intro

    you are not alone i have the same customization number as you @yolo still no update…be patient

  • Karel Komjathy

    Yes this is a global problem/bug!!! You wait for next bugfix update

  • Karel Komjathy

    Probable this is a last firmware for Xperia T,V,TX :(

  • xperianer

    the xperia T works without any doubt better on 4.3
    people who see no difference compared to 4.1.2 are simply liars.
    (even with the many 4.3bugs reported)

    i wouldnt go that far and say i want kitkat, im realist. but if its possible, then it will improve the performance again (i know how omnirom,KK runs)

    4.1.2 to 4.3 on XT is like night and early daytime,
    4.1.2 to 4.4 would be night to sunny lunchtime….if sony not fuck up such update….all theoretical

    im ok with 4.3 now, and i will be more ok if they release some bugfixes^^

  • Mickael

    Zero bugs for my Xperia T, I’m so happy !!! My Ram is perfect, I lov’ Stamina Mod, my battery is more longer.
    Thx Sony, for this phone I like it !!!!

    Buy the 2nd november

  • Abhijit Biswas

    Kitkat having better ram management and minimum fragmentation is highly stable and provides much more processing power with current hardware plus for these on-screen button devices users also get access to immersive mode which is very cool and for many necessary!

  • Abhijit Biswas
  • Dmitry Perets

    Well, I am not saying that 4.3 works the same as 4.1.2, I am saying that it actually works WORSE. So according to your terminology, I am not a liar, and that’s a good thing =)

    I don’t see any performance improvement in 4.3 on my Xperia V. I see exactly the opposite. It takes more time to start camera, it takes more time to wake up the phone even (yes, that’s correct: with 4.3 it takes more time between pushing the power button and seeing the screen – and it is annoying). The “fade in”/”fade out” effect that they were trying to implement with the screen looks really laggy as well.

    Regarding bugs and stability – I think there is no need to comment too much in addition to what people say everywhere. I would just add that I didn’t reboot my phone because of the bugs NOT EVEN ONCE since upgrading to 4.1.2 almost a year ago. But with 4.3 I had already 1 crash and 2 times charging bug (when I connected the charger, but it did’t start charging until I rebooted the phone). This is for less than a month. And the battery drains faster on 3G (because of – known issue).

    I also commented enough about my attitude to changing UI elements.. so won’t comment again.

    In summary, do I want Sony’s KitKat…? Hmmmm… I would prefer just a bugfix that would bring my phone the stability that was taken by 4.3.

  • littlebeetle

    Sharing my issue with my current 4.3 FW.
    1. Phone gets restart regularly if I am on the call for more than 5 minutes
    2. Video ticking noise while recording
    3. Volume bar it’s in full black when attempt to do a screen shot

  • Dmitry Perets

    And again, as always, classical mistake. You are talking about Android KitKat. But this OS runs on Nexus. What runs on Xperia is custom Sony OS based on Android KitKat. How good it will be and how optimized it will be for your Sony device depends much more on Sony developers than on Google.

    Any great RAM management can be easily ruined by non-optimized UI. Right now I have at home three devices running Android 4.3, from two different manufacturers. And believe it or not, they work completely different. Different stability, different performance, different look&feel. I mean.. c’mon… didn’t you use TouchWiz? It is also Android…

    Judging custom software by the underlying Android version is just wrong.

  • Dmitry Perets

    Let me guess… after all this you are still the one who wants Sony to upgrade Xperia T/TX/V to KitKat…?

  • Abhijit Biswas

    Ever since i upgraded SP to 4.3 its been smoother than ever, smoother than anything I have ever used! Mostly because trim support makes sure your phone will always be as snappy as it was out of the box. Even asphalt 8 doesn’t lag anymore on maximum graphics….

    Till date all the Sony devices I have used have excellently optimised android versions on them. Sony is excellent at optimising android for its phones! The only thing Sony forgot on 4.3 was the long press on the notification area shortcut taking them to their setting menu! That is what made me a Sony fan, before I liked samsung!(now i hate them)

    And for touchwiz that is the worst thing ever to happen to android! They can screw up anything, their stupidity makes me hate Samsung especially coz they sell those abominating octa-core processors in my country! Touchwiz is just put on top of android instead of stitching it into the OS, xperia UI is stitched in…(the last sentence is my hypothesis only)

  • Okazuma

    Xperia T or V?

  • Io

    Let me guess… you are one of the supporters of the .295 update polishing and refining theory…?

  • ahmed

    I flashed android 4.3 on my xperia tx with flashtool and yhe battery drops too fast anyone have this problem?

  • Aro

    Przeciez to wiadomo, skoro masz brand t-mobile to update masz zawsze opozniony.. 4.3 wyszlo dla modeli bez brandu

  • Mohammad Shahroz

    yes i have this problem in my xperia T and my problem is worse my xperia T dont detect the charger if phone turns off coz of 4% battery even i turn it on it boots shows the home screen and then turns off again and the only way to charge my phone is i Flash my phone with 4.1.2 firmware and then it gets charging i had this issue twice and i did the same method both time only i know how to do it coz in 0% battery no 1 can Flash the phone :P

  • Actman

    Not until I got an official word from SONY yet, I won’t trust user’s comment.

  • Frode P. Bergsager

    Same problem on my Xperia V, battery is dropping twice as fast as 4.1.
    Another issue is battery life on my SmartWatch 2. Before the 4.3 update SW2 lasted 3 days, now it only last 1 day before I have to recharge.

  • Uli

    The 4.3 is crappy, I loaded the tft file and it lasted about 20 minutes on my phone and reloaded 4.1.2 , 4.3 lags so badly plus the camera is faulty and the list goes on.

    There is a reason my operator is delaying this update.

  • Nikolai ivanov

    It could be Android 4.3.1 ??

  • Dmitry Perets

    Of course I am!
    First, because I got 4.3 on my Tablet Z in December, so I was trying to avoid this “happiness” also on my Xperia V.
    Second, because I knew that it would ruin things, so I didn’t feel like hurrying to get it.
    And now, after receiving it, I don’t see that I was wrong about either of the above.

    But you did’t answer… Are you still waiting for KitKat, because major updates bring so much good…?

  • Dmitry Perets

    From technical perspective, TouchWiz and Sony software are exactly the same type of Android “distribution”. The difference is that – as you said – Samsung did it terribly bad, while Sony did it good. And this just proves my point: judging custom Android-based software (just) by the number of Android version is wrong. You can have two custom releases, based on the same Android version, but being totally different. And you can have a custom release based on 4.1 which works better than the one based on 4.4.

    You forgot to mention where exactly your SP became “smoother” after upgrading to 4.3. I didn’t have too much lags on 4.1.2 with my Xperia V, and I definitely can’t point to anything that started to work smoother after an upgrade. I’ve already named few things that started to work worse though.

    The conclusion is: I don’t believe in major updates. Definitely not from stable and good releases. Definitely not for 2012 phones.

  • Io

    You misunderstood, I was refering to the ones pledging that the delay of the update for ~3 months (from the initial announcement for Dec 13) was caused by Sony polishing the update so that we get a bug free and wonderful update, which wasn’t so at all.
    To answer your question, which by the way was not a proper reply to what I said, I never want a bugged update and I never cried for 4.3 in the first place. Of course it’s nice to have the app drawer, more possibilities in the lock screen, better BT and Wifi, but only as long as it’s not cocking up the rest of the stuff which used to work.
    And Sony had enough time to deliver a nice and bug-free update, but of course they care for the newly released phones, not for the older models.
    Moreover, as I could see the improvement in my Xperia V from the ICS to JB 4.1.2, I am sure they could have improved to 4.3, but all the cock-ups are coming from lousy development job.

  • Dmitry Perets

    Well, regarding the improvement from ICS to JB – my theory is that the best version for almost any particular phone is the second one. So Xperia V was released with ICS and had a lot of initial bugs (release deadlines, major changes blah-blah-blah). Then the second update came, much more polished and optimized – JB 4.1.2. And this one was the best. Any further update for Xperia V will be worse, in my opinion. And this happens for most phones.

    Maybe it is because of the bad sales guys who want you to buy a new phone. But I am not that sure about it. My personal experience tells me that the connection between sales guys and software engineers is normally much smaller that it is believed from outside. So the bugs doesn’t come “on purpose”, but rather because the phone is no longer “on focus”. The management pushes you to release the software for the new flagship, and the old Xperia V is secondary. But the marketing demands also to release an update for Xperia V, because the fans demand it. And of course, any major software update brings a lot of new bugs, so you need to be focused on fixing them. Otherwise you get what you get.

    Anyway, what is the solution IMHO? Clearly, stop releasing major updates for the phones that are no longer “on focus”. Maybe a small bugfix would be OK. But stop fixing what is not broken and stop changing just for the change.

    The fans would never agree with me though… So this is where the marketing comes into play. He doesn’t ask to add bugs! He just demands to release the major update. And the rest comes naturally, without any special “tricks” required.

  • Io

    I am glad that you agree with me on the first part, regarding the poor focus on the older models, since I don’t support the conspiracy theory with bugs implemented on purpose (as you can clearly see from my initial post); Funny how people attribute so much to intention/conspiracy and so less to stupidity, negligence or error – which in my opinion are the real cause for such fuckups.
    However I do not agree with you on your second part: If a serious company takes a commitment to do something, they should do it properly, 2 years of support should mean just that, without bullshit like this… and since it took almost 1 year since the last update for Xperia V (and 7 months from the release of 4.3), I would expect to receive an improvement in the last update and not a drawback…

  • josesl16

    This is probably the battery meter problem. You may just need to re-calibrate the battery meter so that the readings become correct again. Look around google for “calibrate smartphone battery”.

  • Misael Romero


  • Honest Observer

    Hi. I’m surprised it’s the other way around for you: 4.12 (stable) & 4.3 (unstable).

    My Xperia T was annoying when it was 4.12. Slow to shut down, slow to launch small apps, slow to launch camera using the camera button, poor battery performance, slow to wake up the phone using the power button. I am a “ram” & “memory” freak – I don’t keep more than three apps open at the same time & I only have a few 3rd party apps from the play store (instagram, instaweather, kindle, barclays banking & whatsapp). It’s like an OCD thing for me.

    All those things are non-existent on my phone now with 4.3. It’s so stable i don’t even care if we get 4.4 ^.^ Saves me the heartache.

  • Navin Dodanwela

    I have a huuuuge problem with the 4.3 update. Whenever I use Viber (viber calls) the internal speaker shuts itself off and wont turn back on. Volume adjustments don’t make a difference. All media is muted (for example, media files playback, youtube, etc.) until I restart the phone.

    To compound matters, Skype is unstable and crashes often after the 4.3 update. I’d love to go back to ICS, anyone know how?


  • Sepehr Estaki

    I have the same!

  • kagara

    just back to 4.1.2

  • apoorva

    i m sure that the ram optimization would be better cz the bloatware apps usually can be uninstalled or disabled, and basically 4.4 from sony too will be optimized keeping the xperia V 1 gb ram in mind.
    4.3 was always better suited and made keeping in eye the high end spec’s and to be the smoothest andriod OS keeping in eye the demands of user’s. AND that very thing led google to go for 4.4 being optimized for 512 mb ram (as firefox OS came up with it). And it has ram + battery problems with lower end smart phone’s.

    U still don’t get it. Plz root and install the CM 11 nightlies in ur xperia V
    catch the difference urself!

  • Abhijit Biswas

    If while playing music I switched to any app, music would stop playing, that’s fixed, camera quality was fixed which went bad with the last 4.1 update! Games are smoother and faster now, especially asphalt 8!

    Initially asphalt8 always had occasional stutters while in tokyo it always crashed, all that is fixed in 4.3, no lags or crashes! But that is due to open gl es3.0! The entire interface is now smoother thanks to open gl es3….

    T, TX n V don’t support open gl 3 so it won’t be noticeable on them, but if you do get kitkat, you will notice the improvement! Have seen the difference on my friends nexus4, so i can tell you with confidence that kitkat is worth it especially from Sony!

    Will miss our short conversations, u on bbm?

  • Corvo Attano

    Does anybody knows if 4.3 is coming for Xperia V users with 1268-8838 customization number? And is there anyone with this customization number who got their update officially, via PC Companion or directly on device (via WiFi), without using any flashtools? I’m starting to think that 4.3 wont be coming for the devices with this number any time soon.

  • Martin Ambre

    to manny issues on my fone Xperia V

    guys how to downgrade to 4.1.2
    going in boot loop after flashing

    need urgent help

  • Martin Ambre

    how??? to revert upgrade

  • Sepehr Estaki

    do not apply xperia theme on your phone, or in case you’ve applied you should not have sim card pin or lock screen pin, if you have, then you should repair your phone with Sony Update Service.

  • Martin Ambre

    it updates to 4.3

  • Sepehr Estaki

    what’s the problem now?

  • francesco

    new undiscovered awesome bugs uhauhauhauah

  • francesco

    and what about random reboots?

  • Vito

    I think Xperia T/TX/V won’t be fast enough to handle 4.4… on 4.3 there’s less than 300mbs ram free, on 4.1.2 i had like 400mbs. 4.4 update might kill these phones. I’m happy with my 4.3 on Xperia T.

  • Abhijit Biswas

    I know you are a one time poster so commenting on your comment is useless but still for others it might work so….

    The Dmitry guy is behaving like an old guy who is not realising that he talking about the past! When will each new android hardware requirements increased and so updates made the phone bad. But now since 4.1 android has been maturing instead of just evolving so those problems are gone! And now even developers have enough experience to properly optimize android skins to even that is not an issue.

    The only which remains and will remain for ages is that the first update with a new android version will be buggy and have such shortcomings but the second n third updates will fix all that, if one wants great smooth updates, always install the second firmware directly…

  • francesco

    just wait this, actual 4.3 sucks, bugged camera, random reboots…

  • Uli

    Has Sony stopped releasing firmware on the phones due to this new update?

  • Martin Ambre

    battery drains very fast
    RAM usage hits top floors
    after coming out of app it goes back to home screen
    Home screen redraws

    certain apps crashes, even clear cache or reinstall doesnt help

  • Rune Abro

    Dmitri, have you found any workarounds to any of your problems? Can you provide a link to diskussions about the issues? I also experience so many issues on my experia V after 4.3 that I can no longer rely on it for work. Apart from the crazy powerdrain, the phone is now very unstable. Using google maps or streaming data makes the phone crash periodically. Tried reinstalling to no avail. I am so frustrated ..

  • Mr Intro

    thats a good question

  • Dmitry Perets


    Unfortunately, I don’t think there is any workaround. Build 295 has serious issues with stability. My phone crashes several times a week out of nowhere. Complete reboot I mean. I hope we get a bugfix soon, because it is ridiculous… Taking a good stable release and turning it into crap. Sometimes it seems that manufacturers forget that their phones are used to do some work, not just as an entertaiment for fan kiddies who want to get higher version numbers than their neighbors have…

  • Dmitry Perets


    I wish I would have been talking about the past. But my Xperia V crashes few times a week after 4.3 upgrade. I mean complete crashes, with automatic reboot. I didn’t have NOT A SINGLE CRASH like this for almost one year of running 4.1.2. And I already talked about other bugs earlier. So you can talk about the theory of Android being optimized and about the theory that the vendors just change the theme a bit, so it won’t hurt… But just Google for feedback on 4.3 for Xperia V or even read this thread to find people with issues similar to mine.

    No, I don’t have a lot of buggy software (and btw it shouldn’t crash the OS if the OS is not buggy). Yes, I had the same software before upgrading to 4.3. Yes, I tried to wipe and reinstall.

    Furthermore, if you read carefully the posts of others, you can find things like: “man, it is so cool, 4.3 upgrade is so great… it is just rebooting sometimes and eating the battery a bit more, but otherwise it is so perfect!” I am sorry, “rebooting sometimes” and “so cool” don’t come together for me. I didn’t buy Lego or something. I guess it is just different definition of good release vs crap.

    Is this the latest update for the XV 9.2.A.1.199??

    Is this the latest update for the XV 9.2.A.1.199???

  • safa

    I’ve updated my xperia T to 4.3 recently, but after a week I realize that screen lock sound and when talking I can barely hear the other side but walkman player works great and the sound is good. I don’t think it’s a hardware problem. and I don’t wanna flash my XT so soon. Does anyone have any idea how I can fix the problem without flashing?

  • hanry dp


  • doud


  • Abhijit Biswas

    The new firmware is rolling out, hope it fixes the bugs, even i have some minor bugs in SP which I can live with… like the volume bar disappears when using downlaoded themes, lower walkman sound output…

    The only major bug is wifi showing that its connected but has actually disconnected when on standby, but the range is now as good as any other phone out there so I am just waiting for the bug fix, imagine constantly turning wifi on n off to stay connected… So i know how u feel! rest is awesome!

  • Luke

    Just got 9.2.A.1.199 and now my Xperia T refuses to turn on, it gets to the Sony splash screen and turns off again…

  • Divya Bharathi

    Very interesting thing I just come across at – I could choose any number of pants and shirts (from the list) at very heavy discount rates (up to 75% off online) – more we buy more discount – I never seen this before.

  • Rabah Hadjzoubir

    Hi. As you must now officially, the Xperia V will not be upgraded to kitkat. And I agree with you that the 4.3 version is not good in few things. Viber doesn.t work on it , you need two hands for a screen capture ect. So my question is did you find a way to downgrade your phone to 4.1 but directly with the phone without working with a computer because I am not comfortable with it . Please if you can answer me on my box Thank you
