The part bears the product ID 0x31. As seen in [1], Sensortek lists STK3013 as a proximity sensor. But it has been experimentally observed that they do have ambient light sensing capabilities. Furthermore, [2] implements a proximity and ambient light sensor driver for STK3x1x devices, which is also indicative of the fact that these parts are also ambient light sensors.
