Embodiments of this application relate to the motor field, and provide a motor, a camera module, and an electronic device. The motor include a lens carrier, a frame, a magnetic attraction mechanism, and two slide rail mechanisms. The two slide rail mechanisms are diagonally disposed between the frame and the lens carrier on a plane perpendicular to an optical axis direction of a lens and are configured to provide sliding support surfaces for movement of the lens carrier in the optical axis direction to reduce a friction force. A magnetic attraction force generated by the magnetic attraction mechanism is used to abut the lens carrier against the slide rail mechanisms. Because the two slide rail mechanisms are diagonally disposed, structural distribution is uniform, so that an overall force on the lens carrier becomes uniform. This facilitates structural stability, reduces a requirement of the motor on a magnetic attraction force, reduces a requirement for a driving force in autofocus, reduces power consumption and costs, facilitates a miniaturization design of the motor, and simplifies overall design difficulty.

Embodiments of this application provide an image shooting method and an electronic device. The method is applied to the electronic device. The electronic device includes a foldable screen, a front-facing camera, and a rear-facing camera. The foldable screen includes a first screen and a second screen. The front-facing camera and the first screen are on a same side, and the rear-facing camera and the first screen face away from each other. When the electronic device is in a folded state, the second screen and the rear-facing camera are on a same side. The method includes: when the electronic device is in a folded state, displaying a first image shooting preview interface through the first screen, where the first image shooting preview interface includes a first control and a second control, and the second control is used to control switching between the front-facing camera and the rear-facing camera; and in response to the first operation performed on the first control, controlling the first screen to be turned off, controlling the second screen to be turned on, and displaying a second image shooting preview interface through the second screen, where the second image shooting preview interface includes an image obtained by using the rear-facing camera. This method can implement a rear selfie and improve image shooting quality.

Embodiments of this application relate to the field of display technologies, and provide a lens assembly, an optical system, and a display device. The lens assembly includes a plurality of lenses sequentially arranged from an object side to an image side, an optical splitting element, a first quarter-wave plate, and a reflective polarization element that are sequentially arranged from the object side to the image side, and a lens barrel. At least one of the first quarter-wave plate and the reflective polarization element is independent of the plurality of lenses and fastened to the lens barrel; or object side surfaces and image side surfaces of the plurality of lenses include at least one bonding surface, and at least one of the first quarter-wave plate and the reflective polarization element is bonded to the bonding surface. The bonding surface is a quadric surface whose curvature is zero in at least one direction.

Embodiments of this application provide a communication method, and relate to the field of communication technologies. The method prevents an electronic device from entering an RRC connection reestablishment procedure, so that UE can complete an RRC connection reconfiguration procedure. The method includes: A first configuration message is received, where the first configuration message includes a third CA combination. The first configuration message is used for configuring the third CA combination for the terminal. When the third CA combination is not supported by the terminal, a first update request is sent, to trigger a first base station to query a frequency band and a CA combination that are supported by the electronic device. A first query message is received. In response to a first capability query message, first capability information is sent. The first capability information does not include a fourth CA combination, and the fourth CA combination includes a first CA combination or the third CA combination.

This application provides a data transmission method and an electronic device. The method includes: A first device establishes a first signal connection with a first access point operating on a first channel. A second device establishes a second signal connection with a second access point operating on a second channel. The second device establishes a data connection with the first device in response to a data transmission request of the first device. The first device or the second device cuts off a signal connection on a different operating channel from the data connection, which can prevent the first device and the second device from being in a co-frequency and different-channel operating mode, thereby improving data transmission efficiency between electronic devices and enhancing terminal usage experience of a user. A path of the data connection includes any one of the following: a first signal connection and a third signal connection between the first access point and the second device; a Wi-Fi Direct connection between the first device and the second device; or a fourth signal connection between the first device and the second access point, and a second signal connection.

This application discloses a camera module and an electronic device, including a lens assembly, an image stabilization mechanism, a base, and a support structure. The lens assembly is configured to direct outgoing light to an image sensor. The image stabilization mechanism includes a movable stage and a mover assembly that are connected to each other, where the movable stage is configured to carry the lens assembly, and the mover assembly is configured to be capable of being electromagnetically driven, to drive the movable stage to move carrying the lens assembly. The base includes a bottom wall stacked with the movable stage. The support structures are disposed flat between opposite surfaces of the movable stage and the bottom wall, where the support structure can enable the movable stage to translate in any direction parallel to a plane of the bottom wall. In the camera module in this application, the quantity of parts of balls and tracks is also reduced, so that the camera module using the image stabilization mechanism can implement a light and thin design.
