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 garbage data scrubbing method includes obtaining an input/output (IO) busy/idle status of a terminal at a current moment, where the IO busy/idle status includes a busy state and an idle state. When the IO busy/idle status of the terminal at the current moment is the idle state, a discard message is delivered to a storage device, where the discard message includes an initial address and a size of to-be-scrubbed physical space in the storage device, and where the discard message is used to unbind a mapping relationship between a physical address of the to-be-scrubbed physical space and a corresponding logical address.

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: 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: A first device obtains an advertising parameter used by a second device to send an advertising data packet, where the advertising parameter includes an advertising window and an advertising interval. The first device determines, based on the advertising window and the advertising interval by using a preset scanning model, a target scan parameter used by the first device, where the target scan parameter is a scan parameter used by the first device when power consumption of the first device is a preset threshold and a scan-to-discover time period satisfies a preset condition. The target scan parameter includes a target scan window and a target scan interval. The first device performs scanning based on the target scan window and the target scan interval.

Abstract: Embodiments of the present disclosure provide a method, an apparatus, and an electronic device for controlling a display screen backlight, and a storage medium. It is determined, with reference to an included angle between the electronic device and a preset direction and whether there is an object shielding an aperture in a call state, that the display screen backlight is adjusted to be on or off.
