Key points
- Strong magnets from accessories can disrupt iPhone camera stabilization.
- Lens-position sensors are hypersensitive to magnetic fields and vibrations.
- Apple advises users to check if accessories cause image blurring.
Apple has confirmed that strong magnetic accessories can interfere with the rear-facing cameras on iPhones. The tech giant warns that these magnets may disable lens-position sensors, leading to blurry images. This issue affects devices relying on image stabilization technologies. According to Engadget, Apple’s support page now highlights this potential interference.
In plain English
Many iPhone accessories use strong magnets to attach to the phone. These include removable grips, car mounts, power banks, and ring lights. While convenient, these items place strong magnetic fields near the camera. Apple states that these fields can hinder camera performance. The magnets do not affect internal phone systems. Instead, they disrupt the camera’s ability to stabilize images.
The background
iPhone rear cameras use two main stabilization technologies. The first is optical image stabilization, or OIS. It uses a gyroscope to sense camera movement. If you move while taking a photo, OIS adjusts the lens to reduce blur. The second technology is closed-loop autofocus. It uses onboard accelerometers to measure vibrations and gravity. Both systems rely on magnet-sensitive sensors.
What changes now
Magnets can have a pronounced effect on these photo-correction processes. Lens-position sensors are hypersensitive to magnetic field interference. When near certain accessories, these sensors may become disabled. This results in motion blur in photos and videos. Apple suggests that users check if their magnetic accessories cause image blurring. Other factors, like high-amplitude vibrations, can also damage these sensors.
What to do and how to stay safe: Apple
- Check if your magnetic case or mount causes blurry photos.
- Remove magnetic accessories when taking important photos or videos.
- Avoid exposing your iPhone to high-powered vibration sources.
- Monitor camera performance after adding new magnetic accessories.
