The iPhone 14’s new crash detection feature is causing problems for users who ride roller coasters. Apple’s latest phone is reportedly getting a bit glitchy on the rides by dialing 911.

The same crash detection technology is also featured on the Apple Watch 8.

Signage on some of Dollywood’s high-thrill rides tells guests to consider turning their phones off or activating airplane mode before riding.

Crash detection was added as a default feature to all new iPhone 14s and other Apple devices and uses device data to detect signs of a car crash like loud noises and shocks.
