I found strange shutter sound bug.
When the light is low or focus is poor,
Camera shutter sounds like this "Be-be-beep!"
(You can check that bug in my youtube)
That's too strange and annoying.
I already did factory reset few times but nothing changed.
This bug was occured 3~4 days after using this phone.
Is there anyone who found same bug?
How can I fix this bug?
