HP ENVY X2 13" Convertible Touch Laptop

Does this tablet have only a front-facing camera? Or, does it have a webcam on the front and a regular digital camera on the back?

Looks to be a webcam.

Webcam: Front-Facing HP TrueVision Full HD

I don’t see any info on this about a rear camera.

Does this also have a kickstand on the slate part?

Per the features…

Fully adjustable stand
Adjust your PC to the perfect position with the multi-angle stand.
