Shutter sound UPDATE:
Note to all...I was walking around with my bluetooth headset on hanging around my neck and with NO MUSIC PLAYING OR ANY RADIO ON AT ALL...but with the bluetooth headset "connected" to the phone...decided to take a picture...low and behold...no sound. No click! You could hear it in the speakers of the headset, but not outside of it! FINALLY...no NOISE WHEN PICS ARE TAKEN!!!!
Test this yourself...
1. Turn on Bluetooth
2. Attach a Bluetooth headset to your phone...connect it
3. Try to take a picture
4. Whoala! No click noise!!
...mind you...it's not full proof...but at least it works. I always have my bluetooth headset with me so it's not an issue for me. This isn't a fix, but a workaround. Maybe someone smarter than me can exploit this and figure out a fix.
Let me know if it works for ya!
