I found a much simpler method for silencing the annoying shutter sound during a screenshot, so everyone who claims you can only silence a screenshot by deleting the shutter sound file after rooting your device has been incorrect.
All you have to do is silence System Sounds. This won't work for those who want System Sounds for some other reason, but I'm unaware of any reason why I personally want any System Sounds.
To quickly and easily silence System Sounds, just do this (at least, this is how it works on my Samsung Galaxy s7 Edge):
- With 2 fingers, slide down the Notification Panel
- Hold the Sound icon until the Sound and Notification page appears
- Tap Volume
- Right under System, tap the Sound Icon, and the Mute Icon will appear
Congratulations: you can now screenshot in total silence . . . .
