Just wanted to pitch in – the same happened to my iPhone 11 after about 20 cumulative hours mounted to my motorbike on a Quadlock. When it focuses on a certain distance (about 20cm, not closer, not farther) the image goes into “zoom blur” and the phone vibrates and makes an audible noice (full sensory feedback, wow). Out of warranty period too :( Does anyone have any experience whether the same happens on iPhone 12?
