The invention discloses a mobile terminal control method and device and belongs to the technical field of terminals. The method comprises steps of collecting a touch control signal by a touch control sensor disposed in a mobile terminal, determining whether edge touch control operation is detected via an acceleration sensor in the mobile terminal when signal strength of the collected touch control signal is greater than a signal strength threshold value, and controlling the mobile terminal based on the edge touch control operation when the edge touch control operation is detected. In the disclosure, the mobile terminal can collect the touch control signal according to the touch control sensor; when the signal strength of the collected touch control signal is greater than the signal strength threshold value, whether the edge touch control operation is detected is determined; the mobile terminal is controlled when the edge touch control operation is detected, so mis-touch operation occurrence can be reduced; edge touch control response sensitivity can be improved; and mobile terminal operation efficiency can be improved.
