Android 6.0 on Nexus 6 not allowing swipe from bottom right and left

I just installed Android 6.0 on my Nexus 6 and yet after watching videos of features of Marshmallow, I find that I cannot swipe to activate the camera from bottom right or the phone from bottom left. What am I doing wrong or are there switches I need to activate so these actions function?

Does your Moto G have a squiggly thing in your bottom Mic ?

Can you guys check something for me ? you might need a magnifying glass, On the bottom speaker/mic do you guys notice a squiggly thing inside it on the right ?

Also on the left looks like its missing a chunk of something. Looks like 3mm is missing or something.

Is yours like this too ?
