I'm trying to get face detection working in live preview mode using the hardware-based Camera.faceDetectionListener new in ICS. I have tried with Nexus 4, Nexus 7, and a Samsung Galaxy 10.1 tablet and ALL of these devices return 0 for the front camera when I call getMaxNumDetectedFaces. All of the devices support face unlock, though, so I don't understand why none of them seem to support face detection. Has anyone got this working with one of these devices?
