Mobile terminal and method for protecting against mistaken dialing
First Claim
1. A method for protecting against mistaken dialing of a mobile terminal by an inadvertent keystroke, the mobile terminal comprising a distance sensor and a touch screen, the method comprising the following steps of:
- when the touch screen is not locked and is displaying a dial plate icon, activating the distance sensor to detect whether there is an obstruction within an effective distance above the touch screen;
when there is an obstruction, then detecting by the distance sensor a current distance between the obstruction and the touch screen of the mobile terminal; and
when the current distance is smaller than a preset critical distance threshold, then controlling the touch screen to not display the dial plate icon and deactivating the distance sensor by the mobile terminal, wherein the mobile terminal controls the touch screen to keep activated but not display the dial plate icon, and the preset critical distance threshold is 3 mm.

Abstract
A mobile terminal and a mistaken dialing preventing method thereof are provided. The mistaken dialing preventing method is based on a mobile terminal comprising a distance sensor and a touch screen, and comprises: when the touch screen is not locked and is displaying a dial plate icon, activating the distance sensor to detect whether there is an obstruction within an effective distance above the touch screen; if there is an obstruction, then detecting by the distance sensor a current distance between the obstruction and the touch screen of the mobile terminal; and if the current distance is smaller than a preset critical distance threshold, then controlling the touch screen to not display the dial plate icon and deactivating the distance sensor by the mobile terminal. In this way, the present disclosure can automatically deactivate the call program of the smartphone to absolutely prevent mistaken dialing with a very satisfactory effect.

11. A mobile terminal, comprising:
-
a touch screen; a distance sensor, configured to detect whether there is an obstruction within an effective distance above the touch screen when the touch screen is not locked and is displaying a dial plate icon; and a processor; when the distance sensor detects that there is an obstruction within the effective distance above the touch screen, a current distance between the obstruction and the touch screen of the mobile terminal is obtained through the detection of the distance sensor; and the current distance is smaller than a preset critical distance threshold, the processor controls the touch screen to not display the dial plate icon and switches off the distance sensor; wherein the processor controls the touch screen to keep activated but not display the dial plate icon. - View Dependent Claims (12, 13, 14, 15, 16, 17)
