Abstract: An electronic device for determining a type of an audio device plugged into the electronic device includes an audio port configured to receive a plug of the audio device, a plug detection system configured to determine a plug type of the audio device from the audio port, and a display configured to display the plug type. The plug type includes a three-section plug and a four-section earphone plug. The three-section plug is either a three-section earphone plug or a three-section external speaker plug.

Abstract: In a method for adjusting a photographic lamp of an electronic device, the electronic device obtains a preview image from a camera device of the electronic device, and obtains a brightness value of an ambient environment of the electronic device. When a human face is detected in the obtained preview image, the electronic device changes a current output power value of the photographic lamp to be a first output power value, according to the obtained brightness value. When no human face is detected in the obtained preview image, the electronic device changes the current output power value to be a second output power value according to the obtained brightness value.

Abstract: A portable electronic device and an operation method using the portable electronic device include presetting function modes applicable to specific user interfaces of the portable electronic device, and presetting operations in each of the function modes and a command corresponding to each of the operations. Signals are detected from a first and a second proximity sensors of the portable electronic device, and a time length of each signal is calculated. A command corresponding to a current operation is executed if the current operation is determined to accord with one of the preset operations according to the detected signals and the time length.

Abstract: An electronic device and a method enables an unlock operation of the electronic device. When the electronic device in a lock state is moved for the unlock operation, the electronic device receives a three-axis acceleration vector of the electronic device from an accelerometer. The electronic device analyzes three movement directions of the electronic device along three coordinate axes. The electronic device determines whether the analyzed three movement directions are the same as three predetermined movement directions along the three coordinate axes. If the analyzed three movement directions are the same as the three predetermined movement directions along the three coordinate axes, the electronic device is changed from the lock state to an unlock state.

Abstract: A portable electronic device and control method thereof perform an unlocking operation and several page turning operations for a display of the portable electronic device. Light intensities in several positions of the light sensors are detected in a preset time period. The portable electronic device determines whether the operating mode is a predetermined operating mode and determines whether the portable electronic device is locked by the detected light intensities. The portable electronic device unlocks the portable electronic device upon detecting the portable electronic device is locked. Furthermore, the portable electronic executes at least one page turning operation on the display unit upon detecting the portable electronic device is unlocked.
