A mobile terminal able to autonomously recognize when a user requires the mobile terminal to function as a mirror includes a housing, a screen with one-way see-through glass, a gravity sensor, a distance sensor, a front camera, a processor, and a storage device. At least two kinds of information are being collected, namely an orientation of the mobile terminal collected by the gravity sensor and a distance between a face and the screen collected by the distance sensor. Other information as to a facial expression and hand actions can also be collected by the front camera. The information is analyzed and a determination is made as to whether the user wishes to look in a mirror, and the screen will be controlled to be dark and shut down for the mirror function.
