Abstract: Embodiments relate to the field of storage technologies. The method is applied to a flash device whose first physical storage space stores a data block at a first security level and a data block at a second security level and whose second physical storage space stores a data block at a second security level. The method includes: receiving a data write request used to request to write target data, and obtaining a security level of the target data; and writing the target data into the first physical storage space if the security level of the target data is the first security level; or writing the target data into the second physical storage space or writing the target data into the second physical storage space and the first physical storage space if the security level of the target data is the second security level.

Abstract: Embodiments of the present disclosure provide, for example, a Bluetooth connection method, the example method including sending, by a first terminal, a Bluetooth low energy BLE advertising message, where the BLE advertising message includes device information. A second terminal receives the BLE advertising message, and then obtains the device information. The second terminal then matches the device information with prestored device information and, if the device information successfully matches the prestored device information, initiates a classic Bluetooth connection request to the first terminal, where the first terminal then establishes a classic Bluetooth connection to the second terminal. Power consumption of BLE is low.

Abstract: A method for protecting application data includes detecting a deleting operation performed by a first application on first data. The method also includes determining, based on a preset condition, whether to delete the first data of the first application. The method further includes renaming the first data of the first application based on a determination that the first application meets the preset condition. The method additionally includes storing the renamed first data in a memory.

Abstract: This application provides an image display method and apparatus. The method includes: generating and displaying a first image based on first user operation information; storing the first image into a memory; when detecting second user operation information, determining, in the memory and based on the second user operation information, the first image corresponding to the second user operation information, where both the first user operation information and the second user operation information are used for displaying the first image; and displaying the first image. An image displayed for the first time is cached, so that when same user operation information triggers the image to be displayed again, a terminal device may directly capture, from a cache unit, an image that needs to be displayed, and does not need to draw the image before displaying the image.
