Tilt, shake and carry are three things a handset notices about its owner without ever asking. A preview build can now stop specific applications from hearing about them.
The motivation looks like advertising that fires on movement, where a hand reaching for a link gets thrown into a store listing instead. Devices logged into a mainland China store account are the first to see any control at all.
Movement readings have sat in the low-risk tier of Apple’s permission model. Fitness and navigation software does request Motion & Fitness access, yet the raw streams underneath have arrived with far less ceremony, and side-channel work has leaned on them for years to guess at what a device’s owner is doing.
The row itself is marked Restrict Motion Data, and choosing it keeps an application from receiving gyroscope and accelerometer output, per app.
MacRumors and the Chinese outlet IT Home, whose reporting TechNode carried, are the outlets that spotted it in the second developer seed of iOS 27.2.
No regulator, no advisory and no public explanation accompany the change, and Apple has stayed quiet. Controls that surface in a seed can also vanish before a build ships. What matters is where the readings would land: out of a pool that applications dip into freely, and into one that needs a nod from the person holding the phone.
