Abstract
A method for operating an electronic device which is in a first mode is provided. The method includes detecting a grip state of the electronic device, detecting a change in tilt when the detected grip state is equal to or greater than a predetermined value, and switching a mode from the first mode to a second mode when the detected change in tilt is within a set tilt range.
Claims12
A method in an electronic device which is in a first mode, the method comprising:
- detecting, by the electronic device, a grip state of the electronic device;
- detecting, by the electronic device, a change in tilt when the detected grip state is equal to or greater than a predetermined value;
- switching, by the electronic device, a mode from the first mode to a second mode without user authentication when the detected change in tilt is within a set tilt range;
- receiving, by the electronic device, an input for terminating the second mode;
- and
- switching, by the electronic device, the mode from the second mode to a predetermined mode,
- wherein the first mode is a sleep mode, the second mode is a mode in which only a camera module is driven in the sleep mode, and the predetermined mode is a lock set mode.
