Ok so I went to a neighbor who has m8 and it's the same feel in both devices. It's not as if it has huge space to dwindle in, something like a micrometer of space to move. The volume rockers feels really soft and do have lot of movement then the on/off button. I didn't notice it because my case covers the volume rockers.
And thanks for the link, I got back to using the touch gestures even though in some pockets it wakes by my leg. I'll try it.
Edit: it's only a lock, I need 3 fingers wake.
