Abstract: A system and method for reliably detecting when a device has been dropped. In a non-limiting example, a drop detection system may be operable to perform one or more of: fall detection, end-of-fall detection, and/or detection of no motion after the fall. The drop detection system may, for example, analyze information from one or more MEMS sensors on-board the device to detect when the device has been dropped.
