Abstract: Disclosed in an embodiment of the present invention are a two dimension code operating method and terminal, the two dimension code operating method including: scanning a target two dimension code storing option information of at least two options; determining orientation information of the terminal if the terminal scans the target two dimension code; determining a target option corresponding to the orientation information according to the mapping relationship between the scanning orientation and the at least two options; outputting a content corresponding to the option information of the target option. An embodiment of the present invention is employed to improve operability of the two dimension code during operating.

Abstract: Disclosed are a key function control method and a terminal. The method comprises: monitoring an operation on a first key of a terminal, wherein the operation on the first key at least can trigger a primary function and a secondary function, and the primary function refers to a preset logical function corresponding to the operation on the first key; determining whether the operation on the first key can trigger execution of the primary function according to output of a user interface of the terminal; and if not, controlling to execute the secondary function. Also disclosed is a corresponding terminal.

Abstract: Embodiments of the present disclosure disclose a page switching method. The method includes: acquiring switching indication information for switching a first page, the switching indication information including a switching indication direction for switching from the first page to a second page; setting a direction opposite to the switching indication direction to be a movement indication direction of a background page of the first page and the second page; and controlling switching from the first page to the second page according to the switching indication information, and controlling movement of the background page according to the movement indication direction. A relative movement speed for page switching can increase, thereby improving user experience.

Abstract: Provided is a method for a terminal to update an operating system, including: acquiring a terminal identifier that needs to update an operating system; updating a first operating system corresponding to the terminal identifier on a server according to system update information; and sending an update result of the first operating system to a terminal corresponding to the terminal identifier, so that a second operating system of the terminal displays the update result. The embodiments of the present invention enable a terminal to update an operating system in time, and can improve the update efficiency of the terminal, improve the security and stability of the operating system of the terminal, reduce the time cost to update the terminal by a user and improve user experience.

Abstract: Embodiments of the present invention disclose a method for managing applications. The method includes: opening a preset shortcut interface, wherein the shortcut interface comprises a shortcut switch region and an application sidebar region, the shortcut switch region is used to display a plurality of shortcut switch icons each corresponding to one application, and the application sidebar region is used to display application icons each corresponding to one currently run application; and exerting a corresponding operation on the applications each corresponding to one application icon in the shortcut interface and/or the applications each corresponding to one shortcut switch icon in the shortcut interface according to an operation control command input by the user performing an operation on the shortcut interface. Embodiments of the present invention further disclose a terminal.

Abstract: Embodiments of the present invention disclose a method for capturing a screen of a terminal. The method includes: obtaining a screen capture instruction for capturing a terminal interface input by a user, detecting actions of at least two objects touching or approaching a touchscreen and obtaining corresponding operation points on the touchscreen according to the detected actions, determining an area to capture in the terminal interface according to the operation points, and storing the image corresponding to the area to capture as a screenshot. Accordingly, embodiments of the present invention further discloses a terminal. By means of embodiments of the present invention, a screenshot needed by the user can be obtained according to operations performed by the user on the touchscreen, thereby improving user's experience.

Abstract: The present invention provides a method for unlocking a terminal and a terminal. Wherein, the method includes displaying a set of contact identifiers on a terminal unlock interface, obtaining an unlock command input by a user performing an operation on a target contact identifier in the set of the contact identifiers, determining whether or not the target contact identifier is the preset contact identifier for unlock, and unlocking the terminal if yes. By means of the present invention, the protection for private data of the terminal brought by locking the terminal is enhanced, and the security and safety brought by locking the terminal is enhanced.

Abstract: The embodiments of the present invention provides a method for managing application icons which includes the following: displaying at least two selection boxes corresponding to different desktops respectively in a first preset region of the current display interface when a movement operation command input by a user performing a movement operation on a target application icon is obtained; determining a target selection box to which the target application icon is moved; displaying a target desktop corresponding to the target selection box in a second preset region of the current display interface; and placing the target application icon in a specified position of the target desktop according to a placing operation command input by the ser performing an operation on the target application icon.
