My 3a pro was smooth and fine with camera until the shutter sound was on by itself. I know it’s due to South Korea region but since the shutter sound was on, when i took the picture, there is delay in taking picture. Even after I tapped on the camera click the shutter sound came out from the phone but the picture was not taken yet well and the result is always unclear. So is there any way how can I turn off shutter sound or something else?
