Apple is testing a new feature in China that helps iPhone users avoid motion-based advertising prompts, like those “shake to open” ads that activate from everyday device movement, including picking up the phone or riding in a vehicle. The function is part of iOS 27.2 beta 2 and adds a “Restrict Motion Data” toggle in Settings that stops apps from accessing the accelerometer and gyroscope. This appears aimed at curbing intrusive ad behavior tied to motion sensing.
Why Motion-Based Ads Have Been a Problem
In recent months, several apps in China have begun using motion sensors to trigger advertisements automatically when a device is moved in specific ways—simply lifting the phone, walking, or riding over bumps in a car can lead to these ads appearing. Users complained that these motion-sensing ads are disruptive and can lead to unintentional redirects. The new setting seems to directly respond to those troubling ad practices.
What the New Setting Does & Where It Applies
With “Restrict Motion Data” enabled, any app will be blocked from accessing motion sensor data—making it impossible for them to detect accelerometer or gyroscope readings. In iOS 27.2 beta 2, this option is visible for accounts registered with the mainland China App Store. As of now, it doesn’t seem to be available for users outside that region.
So far, Apple has not officially confirmed whether the setting is exclusively for China or if there are plans to expand it worldwide. It’s expected that the feature will remain region-locked when iOS 27.2 launches later this year.
iOS already includes a long list of privacy controls. This addition builds on features like App Tracking Transparency and location permissions, reinforcing Apple’s tight grip on device sensor data and what apps can do with it. Motion sensors are powerful tools for apps—but also ripe for misuse.
At a time when regulation of personalized ads—especially around user consent—is expanding globally, this could also help Apple align with stricter privacy expectations and possibly even local regulations in China. While it may seem a localized fix, the implications touch many broader trends in tech privacy.
Although this “Restrict Motion Data” toggle is still in beta, its rollout will be one to watch. If you often jolt your iPhone—literally or figuratively—it could keep those surprise ads from creeping in without your permission.
Analytical Takeaway: This new motion-data restriction marks another step in Apple’s strategy to give users more control over how apps access sensitive sensors. Even though it’s initially focused on mainland China, it signals a larger privacy trajectory—one where motion sensors, once rarely noticed in policy discussions, become part of the arsenal against intrusive advertising. Going forward, the real question will be which jurisdictions Apple extends this control to and how this influences ad models globally.
