Abstract
Provided are a method and device for automatically controlling a state indicator of a terminal device. The method comprises: brightness of a working environment of a terminal device is detected in real time to acquire a brightness signal of the working environment of the terminal device; a current electric level value of the brightness signal is determined according to a variation of the electric level value of the brightness signal within a preset duration; the current electric level value is determined as a light-on electric level value or a light-off electric level value by using a preset threshold; and the state indicator of the terminal device is controlled to carry out a light-on or light-off operation according to the determined light-on electric level value or light-off electric level value.
