Abstract: A combined type accessory for communications connection with a mobile terminal may include a power supply module, a control module and a function module. The control module and the power supply module can be detachably connected. The function module and the control module can be detachably connected. The power supply module can supply power to the control module and the function module, and the mobile terminal can be in communications connection with the control module so as to control the function module. Embodiments of the present invention further provide a combined type accessory system. The combined type accessory system and the combined type accessory can form various accessories through a variety of combinations, provide abundant applications of the mobile terminal, and result in convenience for people's life.

Abstract: A method for data sharing is provided. The method includes: searching, by a first terminal, for multiple nearby terminals, and establishing wireless connections with the discovered nearby terminals, displaying on the display interface of the first terminal the nearby terminals already wirelessly connected to the first terminal and a transmittable file stored in the first terminal or the nearby terminals, and receiving by the first terminal a file-transmission command and transmitting or receiving a file to or from the nearby terminals. A system for data sharing is also provided. By the above means, operations based on the present disclosure are simple and fast, enabling interconnections of mobile terminals within a close range, a mobile terminal can transmit a file synchronously to multiple terminals for data transmission, and the terminals can share data therebetween, which thus profoundly enhances the user experience.

Abstract: A method and a smart terminal for rotating a picture are disclosed. The method includes steps of: detecting, by the smart terminal, that a touch operation applied on the picture displayed on a screen of the smart terminal includes at least two touch points, and, when a trajectory of each of the at least two touch points is an arc, determining the touch operation to be an operation of rotating the picture, and rotating synchronously the picture in accordance with the rotation direction of the trajectories and the rotation angle. By the aforementioned means, in the present disclosure the picture can be quickly rotated to the desired angle of the user, thereby enhancing the user experience.
