Im running 4.2.2 on my Nex 4.
I found an issue that when you take a picture during a call and using a bluetooth headset, the shutter sound will activate the phone speaker, sending the call audio to the phone loud speaker for 1 second or 2.

Not an issue of life or death, but can be annoying since you will loose call audio for a while and send it to the loud speaker. I was traveling and taking pictures from my cell at an airport shuttle while i was calling a friend and the issue that sending the audio to the speaker some people on the same shuttle gave me :the look: that please be quite with my cell.

Does any one else have this issue? or just me.
