A major firmware update is now rolling out for the Sony Xperia Z Ultra! Just in time for me buying it in the coming months hopefully :)
Firmware build 14.1.B.1.510 includes X-Reality for mobile, one-handed text input and Superior Auto mode for the camera. Sounds excellent! I am very excited to try this device out.
