Maybe I tapped the area twice by accident...earlier today I was using my pre texting and a call came in, I hit answer and it was on speakerphone...granted I had it way away from my face in my hands for quite a few seconds after...did I just double tap the area by accident cause speaker is in the same place as answer seconds after or does it know I didn't put my face to it and engage speaker automatically? (I have no patches for the like)
