Alternatively, in some implementations, the camera module is configured to activate a low power mode in accordance with a determination that the input AC voltage is not greater than the supply threshold. In another aspect of the application, an electronic device includes a device housing and a waterproof button assembly. The device housing encloses at least a plurality of electronic components and includes a front cover plate having an opening. The waterproof button assembly is formed in the opening on the front cover plate of the device housing. The waterproof button assembly further includes a button top, a flexible gasket, a button structure, a plurality of LEDs, and a light guide component. The flexible gasket is mounted below the button top. The button structure, the LEDs and the light guide component are mounted below the flexible gasket. The flexible gasket is configured to deflect in response to a press on the button top of the button assembly. The flexible gasket has a top surface impermeable to water and edges that extend beyond sides of the button top. The edges of the flexible gasket include a first peripheral edge and a peripheral region located in proximity to the first peripheral edge. The first peripheral edge of the flexible gasket makes a water tight seal with a second edge of the opening of the front cover plate, and the peripheral region of the flexible gasket is substantially transparent to visible light.
