I just finished getting the rear lens camera replaced in my 7 month old iPhone 11 - under warranty. I mounted it to the bars on my Tracer 900 GT using a quad lock and 2 hours later I get buzzing, clicking and blurry focusing while trying to use the camera. Waste of money spent on the quadlock. Oh well - i’ll just use it in the vehicles instead. They also recommended not using any magnetic mounts as the same issue can occur.
