[Xperia Z1 General] TheCraig:
I presume you found these in the camera app itself?

Update:

I decompiled SemcCameraUI.apk with apktool, then went into /res/values/strings.xml

And I found this....

Look for yourself for more info: http://pastebin.com/Zu9440uE

I will decompile the first ever SemcCameraUI.apk in the first firmware release to check if they were present then. (If so I have my doubts about this ever getting to our device)

Update: No 4k references in the first ever build. Pretty safe to assume Sony plan to give us Z2 apps.
