[Q][KK St18i] Enable HDR, Panorama and Other features on Google Camera topic

I am Using Xperia Ray [ST18i/Urushi] with a Kitkat - 4.4.4. But there is no Photo Stitching, HDR+ options available.
Also I have been searching for CyberShot Superior Auto for kitkat. which is also not available.
Is there any way to fix this?
