How to disable notification sound in Facebook application I have the Facebook application installed and I can't seem to figure out how to turn off the (really loud and sharp) notifications sound, what I tried so far was


go to Settings &gt; App Settings &gt; Sounds in the App and untick the option
go to Settings &gt; Notifications Settings but I couldn't find a relevant setting


I don't want to mute or lower the device volume because I have other apps with  notifications that are actually important for me, I use a OnePlus2 with Oxygen3.6.1 if it helps
If that's the case. Edit the app with Apk Editor from Play Store. Delete the .ogg files compile it and install. If not so, check whether your phone has notification sound scheme at settings and notifications since you want other apps notifying.
