    What’s new in the update? Better if you could that as week

  • XperiaBlog

    The simple answer is we don’t know. Sony do not publish detailed changelogs, so unfortunately it’s down to the users to see what’s new/different. Obviously, it would be much easier if Sony were forced to give users an idea of what each new update brings.

  • a.hamameh

    And what about me XperiaBlog team!!!
    I’m sorry but I’m the first one who give you that information about the new update for Z2 in Taiwan in comments in the last post so is it fair to say the name of your friends and forget the source who gives you that information???!!!

  • Luca

    Omg guys is this true?

  • XperiaBlog

    We didn’t mean to leave you out – we love all of our tipsters. Thanks for taking the time to post.

  • Sander Puus

    Regarding to the z’s you’re getting 5.0 but SP has reached EOL

  • a.hamameh

    I’m a Sony fan and I want to help this site by sending every update informations when I got them on my Xperia Z2 because you are the first source for Xperia users

  • Ritwij

    Is it supposed to go global or something? I don’t see any certification for the D6502 model on ptcrb.

  • Ritwij

    Z already got 4.4.4 way back and SP won’t get anything after 4.3

  • Kabuto Kouji

    i really hope this helps to fix the LOW notification volume issue =(

  • Kabuto Kouji

    i wonder if this will take care of the Low notification volume issue…

  • My model is the Taiwan version (thanks eBay seller!) and the update was available for me. I’m running the update now, so we’ll have to see if there’s anything of significance I’ll notice.

  • Stanley08

    My best guess. Low Notification volume and battery fixes :) Fingers crossed.

  • Stanley08

    You should Charge your battery

  • Luca

    Too lazy

  • Stanley08

    I know that feel.

    — off topic —-

    Snapdragon 810 chip issues could delay LG G4, Xperia Z4; less likely to impact Samsung Galaxy S6

  • Kabuto Kouji

    me too

  • Kabuto Kouji

    does the notifictaions sounds are louder???

  • Got to chill buddy, we all know. You’ve repeated your self like 4 times in just this post alone.
    Keep calm, it’ll come.

  • Oh I’ll check later. I have a Moto 360 so I have notifications on silent all the time.

  • Vishu

    still waiting for 4.4.4 update for my Z2 on bell Canada. Any info?

  • Wolfgang Feierabend

    Just attempted to update and it bricked my tablet. Have to send it in now. Bye bye tablet for 14 days.

  • ae

  • Joe Doc

    Only for the d6503

  • Valetto Pereira

    Got the update in india too.

  • Sekhar Chowdhary

    Hello Valetto pereira,is it the 23.0.1.A.3.12 version?what are the initial impressions, like batter back up and all

  • Ritwij

    Do you have D6502 or D6503?

  • Valetto Pereira


  • Valetto Pereira

    Yup .12 and i dont see any changes except my diagnostics used to crash now its working.

  • Ritwij

    D6503 wasn’t launched in India. I live in India too but got my D6503 from Singapore.. And no update for me yet!

  • Valetto Pereira

    I bought it without bill. Its imported. It has the brazil football offer launch on box.

  • Sekhar Chowdhary

    D6502?can anyone say is the update rolling for this model?can we flash D6503 ftf with D6502…

  • Ritwij

    Mine has that too. Where is your phone imported from?

  • Ritwij

    Give it a try!

  • Sekhar Chowdhary

    everything going fine but the network is not working..can anyone help in this??

  • z2a user

    I thought that Taiwan Sony had forgot they have another phone called Z2a, and it still in 4.4.2…

  • fnnoname

    I suppose you flashed with flashtool right? Try to flash only baseband this time

  • fnnoname

    Why don’t you try to flash it to older firmware?

  • rygarto

    One thing I noticed was the inclusion of “Cyberon Voice Commander” trial on my phone after installing the update. Unfortunately, it was all in chinese, while I have my phone in English. Uninstalled.

  • fnnoname

    The usual “bug fixes and performance enhancements”

  • Wolfgang Feierabend

    Wish I could. I cant get it to turn on at all.

  • fnnoname

    Flashing firmwares using flashtool doesn’t need you to turn on your device. You just need to connect using flashmode

  • Wolfgang Feierabend

    Hmmm. I cant get the computer to even recognize it. :(

  • fnnoname

    Have you tried turning it off and on again? Lol
    Make sure you’ve installed the correct drivers

    Oh and btw,if you don’t mind..when I first read your name the first thing comes to my mind is a pack of wolves lol

  • Wolfgang Feierabend

    Yeah. I cant get it to do anything.

  • Jiyeon90

    New album update is out

  • guna

    Can you explain me in detail.. This will help me..

  • Justin Taschereau

    same here

  • Matheus

    When D6453 Will receive the update? :-(

  • sachiel

    I have updated this firmware and I can confirm that the notification sounds uses both speakers already. You can turn off ClearAudio if you want a louder sound. I also notice that music sounds louder, probably louder than xLoud before but maybe someone can test it to be sure.

    The only thing they forgot to do is the enable both speaker for speakerphone. It’s still hard to hear the voice through speakerphone. I hope they fix this on the next update.

  • Gandalf

  • David Hvatov

  • Aishwarya
