Abstract: Embodiments of this application disclose a data protection method and system, a medium, and an electronic device, and belong to the field of communication technologies. In embodiments of this application, a first electronic device establishes a communication connection to a second electronic device. The first electronic device is a trusted device of the second electronic device. When detecting a first trigger condition, the first electronic device sends first data to the second electronic device. The first data is used to trigger the second electronic device to enter a maintenance mode. According to embodiments of this application, the first electronic device triggers the second electronic device to enter the maintenance mode, to protect data of the electronic devices.

Abstract: A method for generating a display frame and a terminal device is disclosed. When an execution result of a render operation of each application currently running on a terminal device or a compose operation of an application framework layer of a terminal device meets a predetermined condition, a render execution manner of each application and a compose execution manner of the application framework layer are adjusted. Each application executes a render operation in an adjusted render execution manner to render an image of each application. The application framework layer executes a compose operation in an adjusted compose execution manner to compose a display frame from the images of the applications.
