Abstract: Embodiments of this application provide a volume adjustment method and device, and a system. The method includes: A first terminal device sends a first playback request to a server, where the first playback request carries a model of the first terminal device and an identifier of the first audio. The server determines a first volume value of the first audio based on the identifier of the first audio and the model of the first terminal device. The server determines, based on the first volume value and a preset volume threshold of the first terminal device, a first volume gain. The first terminal device determines, based on the first volume gain and a currently set second volume value, a first target volume value. The first terminal device adjusts volume of playing the first audio to the first target volume value.

Abstract: A method implemented by an electronic device includes steps for displaying a first user interface on a touchscreen. The first user interface includes a first display region, a first control, and a second control. The first display region displays first content. The first control is configured to change content displayed in the first display region, and the second control is configured to control exit from the first user interface. In response to receiving a first operation, it is determined that a region in which the first control is located is a region that responds to a touch operation, and a region in which the second control is located does not respond to the touch operation. A first gesture performed on the first control is received, second content is displayed in the first display region, and a second gesture performed on the second control is received without response.
