Abstract: This disclosure discloses a display method performed by an electronic device which includes a first screen, a foldable screen, and a first camera. The foldable screen may be folded into a second screen and a third screen. Orientations of the first screen and the second screen are opposite. The method includes: when it is determined that the electronic device is in a first preset posture, displaying a first user interface on the first screen, where the first user interface includes an image captured by the first camera; when it is determined that the electronic device is in a second preset posture, displaying a second user interface on the second screen, where the second user interface includes an image captured by the second camera. In this way, in a specific posture of the electronic device, a corresponding camera and display are automatically started for real-time preview, thereby avoiding complex user operations.

Abstract: This application is applicable to the field of terminal technologies, and in particular, to a content display method, an electronic device, and a computer-readable storage medium. In the method, when the electronic device displays, on a first display, a first interface of a first application, if the electronic device detects a trigger operation, the electronic device may display, on a second display of the electronic device, a card corresponding to the first application. Content displayed on the card may be determined based on content displayed on the first interface. The trigger operation may include one or more preset operations, so that content displayed on the first display is switched, based on the one or more preset operations, to the second display for displaying by using the card. This enriches display functions of a multi-display electronic device and improves user experience.

Abstract: An electronic device includes a display screen and at least one button. The display screen is a foldable screen. In a process in which a user uses the electronic device, a function that needs to be responded to by a button on the electronic device may be adaptively adjusted based on a physical form of the foldable screen of the electronic device, so that a button function that conforms to a using habit of the user can still be provided when the foldable screen of the electronic device is in a different physical form.

Abstract: Embodiments of this application relate to the terminal field and disclose a data transmission method and a terminal, to increase a speed of data transmission between terminals and ensure stability during the data transmission. The method includes: A terminal establishes a wireless connection to another terminal; in addition, the terminal establishes a USB connection to the another terminal; then, the terminal can display a first interface, where the first interface includes at least one piece of candidate data; a user may select to-be-transmitted data from the at least one piece of candidate data after performing a first input on the first interface; and the terminal may send the to-be-transmitted data to the another terminal through the wireless connection and the USB connection after the user performs a second input on the first interface.
