Android 4.4.2 Update for Sony Xperia Z1, Xperia Z Ultra, and Xperia Z1 Compact Rolled out to Fix Sound Bug

Soon after the initial Android 4.4.2 KitKat Update for Sony Xperia Z1, Xperia Z Ultra, and Xperia Z1 Compact was made available for download, many owners complained they are experiencing sound issues. Sony promised about a week ago that an OTA update that will address the issue will be released soon and now they delivered.

As you may know the sound bug that was annoying the users was making their devices play sounds through the internal, rather than the external speaker. The Android 4.4.2 KitKat update that is now being pushed to Sony Xperia Z1, Xperia Z Ultra, and Xperia Z1 Compact owners is labelled 14.3.A.0.757, and replaces the previous KitKat build 14.3.A.0.681.

Just like any other new firmware, the Android 4.4.2 KitKat 14.3.A.0.757 update for Sony Xperia Z1, Xperia Z Ultra, and Xperia Z1 Compact is being rolled out in stages, meaning that some of you might not be able to download and install it right away.

The folks at Xperia Blog have more information on the regions where then new firmware update is being rolled out. According to them, the Android 4.4.2 KitKat update for Sony Xperia Z1 is live in Austria, Germany, Hungary, Netherlands, Poland, Slovakia, and Sweden, the Sony Xperia Z1 owners can update to Android 4.4.2 KitKat in Russia, France, China, Germany, Israel, Poland, Sweden, Italy, Austria, and Philippines, while the Sony Xperia Z Ultra Android 4.4.2 update is being rolled out in the UK and Germany.

Of course, the 14.3.A.0.757 update will expand in other regions too in the next few days. When your device will be eligible to receive the new update you should receive a system update message in the notification area. Anyway, it’s also worth checking for the update file manually under Settings > About phone > Software updates > Check now. Alternatively, you can grab the USB cable, connect your smartphone to the PC, and check for the new firmware using the Sony PC Companion.

Are there any Sony Xperia Z1, Xperia Z Ultra, or Xperia Z1 Compact owners among you? Have you received the new Android 4.4.2 14.3.A.0.757 update on your devices? Where are you based in? Please let your fellow Xperia owners know in the comments section.

  • Ross

    I updated using PC comp program on the 11th but still feel this 14.3.A.0.757 update is not as good as the original Jellybean software. Unlocking the phone produces a clicking sound from the speaker. Battery life has improved though.From Singapore

  • Buck34_&

    Hi I have been notified that the 4.4.2 14.3.A.0.757 update is available. Using the firmware ending .681 i had the following issues like others; low sound for all notifications, no call log so if i didn’t hear it ring i couldn’t see who the missed call was from. The screen flickered or was slow displaying things and sometimes i’d close one app and the camera would open or perhaps another app. My main camera seemed ok but not what Id expect from a 20.7mp camera.
    The front facing camera seems very low quality and again not what you’d expect especially on a large HD screen.
    That said over the lsat month these issues haven’t bothered me much as i tend to only take the odd picture or short video.
    Ive had NO overheating issues and see/have read that those who have installed 4.4.2 14.3.A.0.757 suffer this and other issues. This makes me reluctant to install it however ive decided to give it a go, in for a penny in for 6000 of em .
    Im in the UK in the South East (west sussex) and im with O2 .

    I was notified of 4.4.2 14.3.A.0.757 today 30th April 2014.

    I’ll pop back with my findings tomorrow.

    wish me luck Rob

  • mel

    I am in australia and have a Sony Xperia Z1 and my phone is still build no 14.3.A.0.681 – same sound problems as others – very frustrating
