Apple warns magnets near iPhone camera can blur photos

Apple says strong magnets near an iPhone's rear camera can interfere with the sensors used for autofocus and image stabilisation, producing blurry images. Magnetic-closure cases and car mounts are cited as risks, and strong vibrations such as those from powerful motorcycles can permanently damage camera sensors.

• Magnets reduce motion-detection accuracy and limit lens movement
• The camera can still shoot using other stabilisation modes
• Apple advises avoiding accessories with strong magnets near the camera
• Strong vibration, such as from motorcycles, can permanently damage sensors
