Perhaps the most important of the new changes in the new firmware is the addition of an option that will allow users to tweak their respective device's white balance. As pointed out in the tweet above, Bluetooth music streaming has undergone some unknown improvements, along with e-mail and Wi-Fi. As always, minor bug fixes are a part of the new code. We currently have no information as to when (and if) this update will seed for the few lucky owners of the Z1 Compact. Moreover, we're unaware of when exactly Sony will push the anxiously expected Android 4.4 KitKat update to its flagship devices, though rumors have, interestingly enough, indicated a late January/early February roll-out.
Firmware update for the Sony Xperia Z1 and Z Ultra now seeding, brings white balance tweaking and more

got it in Germany & it took care of all the bugs I noticed with first 4.3 update....don't know why I have this feeling that the 4.3 update in first place doesn't make almost any differences. I don't know why we didn't get the 4.4 kitkat directly

I'm assuming that Z1S users do not get this update because they already have the capabilities. At least I can stream music, tweak white balance settings, etc., already.

I wanted the z ultra to see how it compare to the note, but I wish they had put a nice camera, the screen size was perfect.....
