Quad lock now produce an anti-vibration add-on for their mounts. I’ve tried it with my iPhone 11 and so far no problems. Previously without the anti-vibe the camera died after one trip. Quadlock appear to have done some fairly extensive testing with this so hopefully there is now a fix for mounting phones with image stabilisation to motorbikes. By the way, I am not employed by, or affiliated in any way with Quadlock. Just a genuine customer with a working solution.
