Abstract: Electronic devices and methods for providing location information are provided, of which a representative method includes: generating sensor readings corresponding to sensed motion of the electronic device; determining a reference location information; computing a GPS-fused location information based on the reference location information and the sensor readings; generating a GPS-required event based on a change of the GPS-fused location information; generating a GPS-not-required event responsive to the reference location information being determined; receiving the GPS-fused location information and one of either the GPS-required event or the GPS-not-required event; responsive to the GPS-required event being received, operating the GPS receiver in a location information-acquiring mode during which the GPS receiver generates geographical location readings; and responsive to the GPS-not-required event being received, operating the GPS receiver in a power-saving mode during which the GPS receiver is deactivated.

Abstract: A method executes a speed detector and a timer to answer a phone call while a user is driving. The user can set a predetermined velocity of a mobile phone and a predetermined time period to determine whether to answer the phone call while the user is driving. When the mobile phone receives the phone call, if a velocity detected from the speed detector is greater that the predetermined velocity, the timer starts to count a time. If the counted time is greater than the predetermined time period, the mobile phone answers the phone call automatically.
