According to the linked paper, Firefox is the only Android browser which allows full 200 Hz sampling of the gyroscope via the DeviceMotionEvent which can lead to using the gyroscope like a microphone.

The spec suggests limitting the frequency of events to 60 Hz:

but we should probably do the same as Chrome (25 Hz cap) or Opera (20 Hz cap).
