1. An electronic device, comprising:
a screen;
one or more processors; and
a memory coupled to the one or more processors for storing instructions which, when executed by the one or more processors, cause the electronic device to:
detect a first user operation;
lock the screen of the electronic device in response to detecting the first user operation;
while the screen is locked and not displaying a fingerprint recognition identifier, detect a second user operation in a fingerprint recognition area based on a capacitance of the screen, and obtain a first fingerprint from a user; and
unlock the screen when the first fingerprint is valid.
