How to turn off the camera shutter sound on LG G2 mini?
You need to be rooted to do this!


Download and open any root browser. (I am Using Root Explorer for these instructions, ES File Manager works also)
Go to System
Go from Read Only to Read/Write
Find Biuld Prop
Open with text editor
Find ro.camera.sound.forced
Change the 1 to 0
Save Changes
Reboot
