A method for unlocking touch screen, electronic device thereof, and recording medium thereof are disclosed. A graph with a boundary is displayed on a touch screen. Then two fingers touch the outside, the inside or the boundary of the graph and move outward or inward separately. Whether the touch screen of the electronic device is unlocked is determined based on whether the distance between the moved two fingers is larger or smaller than a default value, or whether the distance difference between the two fingers before and after moving is larger than a default value. |
