Strong magnets in iPhone accessories can disable rear camera sensors

Magnetic fields affect lens sensors

The rear-facing cameras use specific technologies to keep images steady and in focus. These internal components include sensors that detect lens position with high sensitivity. When strong magnets are placed near the device, these sensors can become disabled.

Common accessories create interference

Users often attach grips, mounts, or power banks that rely on magnetized metal plates to stick to the casing. Such items generate magnetic fields strong enough to disrupt camera function without affecting other internal systems. Apple notes that images may blur if these accessories are used too closely.

Vibrations also cause damage

High amplitude vibrations from sources like powerful motorcycles can lead to lasting harm for the camera sensor. This issue is separate from magnetic interference but represents another risk to the new hardware. Apple advises users to avoid both strong magnets and intense physical shaking.
