DeviceMotion from expo-sensors provides access to the device motion and orientation sensors. All data is presented in terms of three axes that run through a device. According to portrait orientation: X runs from left to right, Y from bottom to top and Z perpendicularly through the screen from back to front.
You should always check the sensor availability before attempting to use it.
Returns whether the DeviceMotion API is enabled on the device.
On mobile web, you need to request permissions for a sensor in response to a user interaction (i.e. touch event) before you can use this module. For example, Accelerometer.requestPermissionsAsync() If the status is not equal to granted then you should inform the end user that they may have to open settings.
On web this starts a timer and waits to see if an event is fired. This should predict if the iOS device has the device orientation API disabled in Settings > Safari > Motion & Orientation Access. Some devices will also not fire if the site isn't hosted with HTTPS as DeviceMotion is now considered a secure API. There is no formal API for detecting the status of DeviceMotion so this API can sometimes be unreliable on web.
