IPhone 6 version Doesnt work

Tried this several times on different surfaces the vibration in the phone does not spin the phone in the circle properly. One time I tried it and it just kept buzzing and shifting around and barely moving and all the second time it started to rotate a little bit but barely even made a quarter of a circle. The first surface was wood the second was glass.
