Abstract: This application discloses a fingerprint enrollment method and a related apparatus. When an electronic device enables a fingerprint enrollment mode, and detects an input (a touch operation or a friction sliding operation) of a user for a fingerprint collection region, the electronic device may collect fingerprint information of the user, and determine an enrolled region based on the collected fingerprint information. If an area of the enrolled region is less than a preset value, the electronic device outputs an enrollment prompt, where the enrollment prompt is used to prompt the user of fingerprint information to be input in a next step. If the area of the enrolled region is greater than the preset value, the electronic device outputs a completion prompt, where the completion prompt is used to prompt the user that fingerprint enrollment is completed. In this way, fingerprint enrollment efficiency can be improved.

Abstract: Circuit techniques reduce or prevent audible artifacts in a Universal Audio Jack (UAJ) interface circuit, improving handling of mis-configuration/mis-attachment of devices. The interface includes at least one terminal for accepting an audio input signal or providing an audio line output signal coupled to an input or output of a first audio circuit. The first audio circuit operates from a low voltage domain and receives the audio input signal or provides the audio line output signal. A second circuit operates from a higher voltage domain and a switching circuit couples the at least one terminal to the second circuit. The output is slew-rate controlled to control a transition time of the output, so that audible artifacts in the audio input signal or the audio line output signal that could be generated by the switching circuit connecting the second circuit to the at least one terminal are avoided.
