I use the QuadLock case and moto mount, they offer (and I have) an anti-vibration plate that fits between the mount and the phone. It cuts the vibration quite a lot, but deff not 100%. Only been using it on the Ambo (luckily not a 'high powered' bike lol) for about 2k miles. We will see how it goes.
I've had several iphones over the years develop the camera fuzz/blur issue, had no idea it was associated with vibration messing up the camera. But none of those phones were ever hard-mounted to my bike.
