Sony may be in the process of adding some screen calibration functions to their forthcoming Sony Xperia Z and Sony Xperia ZL smartphones. This will likely be a nice feature for those users who are interested in doing some fine tuning of the overall screen display for their device. A screen capture of the settings reveals the ability to adjust white balance, color saturation and color hue.
The screen captures come from a Sony Xperia ZL handset. Assuming the function remains available on production units, it seems likely it would also be available on the Xperia Z.
