Major Xperia M firmware update certified – could this be Android 4.3?

Xperia M dual_15.5.A.0.16Sony Mobile has just certified a major new firmware update for both the Xperia M (C1904, C1905) and Xperia M dual (C2004, C2005), which by all indications could be Android 4.3.

The PTCRB website shows that the Xperia M has firmware build 15.4.A.0.21 certified, which follows the last update with build 15.1.C.2.8 (another update 15.1.C.2.9 was certified yesterday but we do not expect it to be released).

The move from 15.1.X.X.X to 15.4.X.X.XX suggests that this is a big update. We already know that Vodafone Aus was scheduling testing of Android 4.3 firmware for the Xperia M, so there is a good chance that this could be it. Xperia M has been languishing with Android 4.1.2, whilst the Xperia M dual is currently running Android 4.2.2.

The Xperia M dual PTCRB certification has also seen a similar jump in build number from 15.2.A.2.5 currently to build 15.5.A.0.16. Once again a very big template jump from 15.2.X.X.X to 15.5.X.X.XX. Another update was certified yesterday with build 15.2.A.2.14, although we don’t expect this to be released. Hopefully, this points to good news for Xperia M owners and perhaps an Android 4.3 update soon.

  • xperiaDROID

    Good news, Xperia C and E should be next.

  • amir

    Why wont Xperia L receive 4.3 update but Xperia M will????

  • wim den boer


  • Reza

    Because XM is newer & better :p

  • Nishanth

    Nice to know that Sony is trying to update most of their products no matter whether that is flagship or mid range unlike other manufactures who concentrate only on flagship models ..

  • amir

    XM is not better than XL , they’re almost the same.

  • Abhijit Biswas

    Coz that will get 4.4 directly!!! Like SP didnt get 4.2 and got 4.3 directly!

    Or since this is such a big jump in firmware build, SOny might want to optimize 4.4 on their weakest phone so that making it work on higher devices that easily!

  • Abhijit Biswas
  • ShinOrochiX

    Lol doubt the E, but agree with the L & C. I just don’t get Sony’s update schedule, my not just update the L/M maybe even the SP to the same android version at similar times. Now I feel quite bad to see my L running on a buggy 4.2.2. Furthermore the release of 4.3 just decreases the chance of getting Kit Kat. We all know what Sony is like.

  • ShinOrochiX

    He is being sarcastic. ;-)

  • Zeke

    I like the way you think. We can only hope.

  • Zeke

    Lighter and smaller could be considered better for a few people.
    Granted, most of the XL spec’s are higher.

  • amir

    When will be the second wave of updates?

  • Amir Hosein

    Hope it will be directly updated to android 4.4 as the latest update……

  • Zeke

    XPERIA C has a Mediatek chipset and may have it’s own schedule compared to Qualcomm driver rollout.
    XPERIA E only has 512MB memory, Adreno 200 and single core processor.
    Sony would probably say buy an XPERIA E1..which, interestly, also only has 512MB memory.

  • Saurabh

    M before L, What’s on your mind Sony?

  • xperiaDROID

    Really? -__-

  • Buat Komentar

    yeah.. nice shoot..!

  • Xperia user

    4.3..??sounds like 4.4 kitkat for me…:DDDDD

  • leaks

    I find it rather odd as a XT user that we are under investigation as low end phones get updates without delay

  • saif

    It’s first major update In 6 month of release. Fair enough.

  • saif

    Xperia L will also get it and you have AOSP option too

  • yanglokal

    Stock Androd 4.4 UI was same with Sony 4.3 UI :D

  • jet199

    If XM gets it then XL will get it :D

  • Akash249

    What about L? : -( ….how come M is given preference….now L has some irritating issues like volume getting reduced drastically after finishing a call….I have to reboot every time for the volume to get to the normal range…some times the system hangs up….Hope SONY does something about this….I want KitKat! :D

  • Shantanu Mukhopadhyay

    Before rolling out this firmware update as 4.3 for Xperia M (Dual) please note the following bugs/suggestions & kindly fix those.

    1. Fix the fast battery draining problem since last firmware update (15.2.A.2.5)

    2. Back camera performance improvement as it’s just not up to the mark of a 5MP camera.

    3. Increase the walkman volume as Sony used to be a brand name for it’s sound quality.

    4. Improve battery performance for longer power backup.

    5. Option to move apps to the memory card.

  • Shantanu Mukhopadhyay

    no of now at least

  • hyper0926

    When for XL

  • Xperia user


  • RHBH

    Now I’ll rant like a Xperia SP user.

    Where is Z1 4.4 update?!?! GRGRGRGR!!

  • yanglokal

    Only a bit. XperiaBlog was posted a post about the different of Android Stock 4.4 with Sony 4.3 UI, just see that post :D

  • What about xperia L?

  • pars71

    i hope it will have App2SD function (M has low internal storage that’s only 2 GB available!)

  • Danny

    I’m not very enthusiastic about Sony updates unless the change their policy on apps to SD. My Xperia M dual C2004 came with 4.2.2. My previously 4.1.2 Xperia L C2104 had that option. These are 2 low end xperia smartphones with only 2 GB and 4GB, respectively. Very little when u want to install lots of apps, it fills up very quickly with just 20 or so apps.

    I also had the LT29i Xperia TX, the C6606 Xperia Z and currently the Z1s, all came with 16GB, while Z1s is 32GB. Good enough storage, but all considered flagship high end models with high price tag.

    Fyi, not everyone wants to root their phone.

  • Simon Paul

    S… It cant able 2 move apps 2 sd card bcz of low internal memory

  • Ben Ling

    the sony guys better be quick with the update// very dissapointing tht not able to download games in the sd card. very low internal memory. the option to transfer data n apps to sd card is a must

  • Abhijit Biswas

    There isn’t much thinking actually! Its only logically especially since it has all the necessary hardware! and the new LG L40 phone has the same processor(with same clockspeed) and same RAM as XperiaE1, is running kitkat! So even that phone will get kitkat so each phone will get updated to kitkat! That was google’s intention with kitkat! Having kitkat on 1billion phones!

  • Abhijit Biswas

    What are you talking about? Low end phones which have 4GB internals are the ones which are in the most need for move apps to sd card!

  • SM

    Well, so you don’t want the rest four features/problems to be implimented/solved?

  • SM

    source? release date (if you have)?

  • Abhijit Biswas

    At Sony’s lab being worked upon…

  • Abhijit Biswas

    Battery drain is occurring coz last update spoilt stamina mode and some other things, so you will have to repair your phone after next update! (repair if drain doesn’t stop)

    Camera improves with each update so that will happen, especially with 4.3/4.4 update….

    M already has excellent loud n clear sound quality, you are crazy to ask more, only HTC phones with boomsound speakers can perform better!

    Once battery drain is fixed with update, the phone with automatically last long, no other phone with that screen and battery efficient processor has that big a battery so now just sign d petition!

  • SM

    Well, for the sound matter let me tell you I was a proud owner of sSunderstand my expectation level from sony used to be once upon a time. Lastly, I’d like to ask you what handset are you using currently?
