Xperia Z1 Compact_14.3.A.0.761A small firmware update with build number 14.3.A.0.761 has been certified for the Xperia Z1, Xperia Z Ultra and Xperia Z1 Compact. The Android 4.4.2 KitKat firmware is likely to offer bug fixes over the previously released firmware with build number 14.3.A.0.757. The last firmware fixed the sound bug issue prevalent in the first release of KitKat and quashed a number of bugs that people were having. We expect this new release to bring further stability.

    Good going Sony!

  • hansip

    Does not expect anything different though, it has been smooth sailing for me with 757. Likely just a testing firmware.

  • Fanboy

    Why sony still not fixing the wifi direct

  • Abdul Ghani

    Updated this on my z1 compact, nothing noticeable…

  • oki

    Please, fix freezing camera screen, when pressing camera button and trying to capture. (Quick launch)
    And fix Update Center’s “silence” please.

    actually its Update CentRE, not CentER

  • Renato Laporte

    Did you do a clean isntall?

  • Mirrorpurple

    ITS ABOUT FUCKING TIME

  • Abdul Ghani

    u already got the new certified update ??

  • rick23ro

    On my menu I see ‘Update CentER’, do you want a print screen?

  • Timbo1

    Depends how you have your English setting. UK or USA.

  • Chaturanaga Manchanayake

    Thank you for clearing that dude up there :P

  • Chaturanaga Manchanayake

    Why do you have to clean install it all the time? why do you have to back up everything clean install all the time? doesn’t the PC Companion do it for us?
    It’s purpose to do it so right?

  • Chaturanaga Manchanayake

    Yea even didn’t get it on Z1. very weird. been refreshing it.
    I think Sony should push that into playstore also like they did with their Keyboard.

  • Xperian

    Same here, I`m using Z1 C.

  • Renato Laporte

    PCC does incremental update.

    If you update trough Sony Update Service, it will download the whole system and do a clean install.

    Why is a clean install needed?

    Well, most of time it isn’t, but with some bug fixes, it may happen that in a specific case, due a different setting or due a problem with an app the system may bugdown after an update.

    And actually, this happens with all systems, and for my self, I try to do a clean install everytime, even with iOS (last time I tried an OTA update on iOS the iPhone got bricked)…

    The big difference here is: the way that Android does backups… with itunes you can backup every little thing, even the position of every icon on the screen, and you can also backup apps and application data.

    In Android, with Sony PCC, you can backup a few things, another few things like some settings goes through Google, apps may download automatically from the playstore, but no app data or interface changes can be backed up in a easy way.

    For my app data backup I use Helium.

  • Sarath Saleem

    I have an issue with sorting call logs and messages. Before update i can see the call logs and sms are sorted by date , now its the time used frequently or somewhat else

    How can i sort the logs/sms by date/time ?

    issue found in 4.4.2 — 14.3.A.0.757

  • SweDuck75

    I really hope it’ll fix all camera-issues. The camera is one of main reasons to why I bought the Z1 Compact.

  • KD

    after the kitkat update, i have a problem which is my z1 mobile keeps connecting to wifi connection even when i turn the wifi off. i searched in the setting but couldn’t find any option to stop it. some times i just want to use my 3g connection at home but it keeps disconnecting and connect on the wifi. any idea about that guys ??

  • Xperia

    i have problems when i connect my phone to my pc keeps freezing half way through when transferring files hope this update fixes it!

  • Xperia

    i have same problem

  • Sachin Mittal

    Battery backup is decreased and phone overheat

  • Sachin Mittal

    The default ring tone named Xperia volume is decreased in kitkat

  • Plus+

    Go to Setting > WiFi > Advance WiFi(the 3 dot on the right bottom) > “Untick” the Scanning Always Available.

  • Xperia

    i already have it unticked

  • Boris J

    Since the last update things are smooth except battery drain, heat and ram usage. Hope this gets fixed in this update.
    Cam is ok in my z1… Last update works fine but needs stability. Hope sony hears our problems from z1 owners.

  • Boris J

    Same here but download the apk file from this blog and install it.. It’s simple as that.
    We really need system updates more important than others…..

  • Boris J

    This just got certified and not yet released. You serious that you got this update? Haha

  • Boris J

    I don’t think so…. But I like the way how it is now

  • Ridhwan Azizan

    Nowadays Sony take seriously on updates.. Good job SONY!!!

  • Vina Guillaume Teko-agbo

    still having the sound bugs after updating to 757. Hope the 761 will definetly fix the problem

  • Chaturanaga Manchanayake

    Yea that’s the good thing about the apple when it comes to do a full back up with itunes, hope they’ll have a pc app which does the same job unlike Helium. Yes I do use helium too. Such a great app.

    off topic :

    does anybody having some problems with “miracast” connection after kitkat upgrade ?

    4.3 didn’t have this problem , although it was slow as hell , unlike nexus 5 , nex 5 was fast!

    i hope sony see into it in the next update…

    It’s not general camera-issues as in the thread you linked, it’s how bad it became when upgrading to KitKat. It takes forever to open the camera and it’s often unusable in third party apps such as Instagram.

  • daffydkjones

    LOL, you didn’t update this you tool, it’s just been certified

  • gtop

    Not true, you can backup app data via PCC under Other (and using the on-phone Sony Backup app) and you can also backup manually-selected folders.

    Plus Sony devs confirmed that there’s no difference at all in updating via PCC or SUS apart from the (optional) reset.

  • Ratha

    Same here for my Z1 -_-

  • Fam

    At first no. But when I plugged my earphone, music still goes out through the speaker. I needed to unplug and plug the earphone again for it to work normal.
    I dont want to do that everytime So I thought I should try repairing it via SUS. I backed up my data and all and then repaired. After that, I was possitive that the bug was gone. I plugged my earphones the pressed play button, the bug is still there. It didn’t solve that issue yet.
