Abstract: Systems, methods, and computer-readable media are disclosed for ambient light sensing using light guides. In one embodiment, an example device may include a cover layer, a light guide, a light emitting diode disposed adjacent to an edge surface of the light guide, and an ambient light sensor disposed adjacent to the light emitting diode. The ambient light sensor may be configured to sense ambient light that propagates through the cover layer and the light guide.
