In a recent published support document Apple notes that exposing your iPhone to high amplitude vibrations at certain frequency ranges, similarly from that of a motorcycle engine can have a bad effect on phone’s camera system.
Some iPhone models, according to Apple, have features including optical picture stabilization and closed-loop autofocus (AF) to help improve image quality. Understanding the fundamentals of how these features work might help you understand why vibrations might cause them to fail.
Optical image stabilization works in tandem with the phone’s gyroscope sensor. As you may be aware, if you move the camera too much when taking a picture, the image will get blurry. This is especially true in low-light circumstances when the shutter must remain open for longer to collect more light.
Caution to be taken
Motorcycle engines with high power or volume produce intense high-amplitude vibrations that are transferred via the chassis and handlebars. Due to the magnitude of vibration in specific frequency bands generated by motorbikes with high-power or high-volume engines, it is not suggested to link your iPhone to them.
Attaching the iPhone to small-volume or electric vehicles, such as mopeds and scooters, may result in “comparatively lower-amplitude vibrations,” according to Apple, although the firm suggests using a vibration dampening attachment to reduce the chance of damage to OIS and AF system of the phone.
Apple also advises against using the device for extended periods to reduce the chance of harm. Because OIS is available on iPhone 6 Plus, 6s Plus, and later, and closed-loop AF is available on iPhone XS and later.
