Sony bumped the Xperia Z1 and Z Ultra to Android 4.3 in December, but a new software build is starting to make its way to users starting today. This one has build number 14.2.A.1.136, but it's still Android 4.3 – Sony is just doing a little housekeeping.

The new update adds a white balance setting for the display and makes improvements to WiFi performance, Bluetooth music streaming, and email. Most users have only been able to get the update through Sony's PC Companion and Mac Bridge apps so far. Presumably it will slowly make its way out to more users via an OTA soon.

    Makes me wonder why they didn't start with 4.4 KitKat, but instead took time and put money into an Android version that should soon be replaced by another.

    On the other hand:

      Or maybe it wasn't a matter of taking much time or money to do. This looks like it might be functionality that exist in the Sony Xperia Z1 Compact, so perhaps it was a relatively small thing to port it to the Z1 and Z Ultra.

      I know I have seen people in Z1 Compact related news comment how they wanted the white balance thing, so I suppose those people would be quite happy to receive this update.

      U r so stupid they did it cuz some people had problems and freezes so they fixed it with this update so that the new update which is kitkat they will focus on now features instead of fixing everything in kitkat and not bringing new features and try to buy z2 in there future cuz they will focus more on the z series

    I can't update my phone they say Sony update engine failed error plz help me

    • Fabio Krauss Stabel

      I had the same issue. Then it worked... I guess you need to reboot the phone without connecting. If it doesn't work, try rebooting the computer. Are you using a Mac?

      • Ibrahim Mohammed
