I have an OPO 3 and I was wondering if there is a possibility to turn off the notification sound for all app, but I would like to retain ringtone sound as well as vibration.
Normally on Samsung S6, there's a possibility to do this when you press the Volume rocker key.
My device is rooted and have Xposed installed. I tried Ringer & Notification Volume unlink xposed module but that doesn't seem to work.
This is something that I miss very badly, it's tragic that google didn't encompass this feature by default.
