While I do think the sensor is a great idea, it is very, very poorly made. For a multi billion/trillion dollar company, they could do better. It really is activated by small moisture, and I think that should be changed. My phone's sensor says its been dropped. It has never even been touched with wet fingers. It's just gotten moist from being in my pocket a lot. So if it ever breaks, I can't do anything because its humid where I live?
