Answer to "Will shaking damage the image stabilization?"Yep - I’ve now gone through 2 IPhone XR rear facing cameras - both following long rides that had a fair amount of dirt road sections. Have been using the Quad Lock. I’m suspecting that system is more prone to transfer the vibrations directly from the bike into the phone - as opposed to other mounts that use a ball hinge for instance. Gonna try a new mount - If that breaks the phone camera again I think I’ll have to spring for a GPS.
