Now, if you want to adjust the volume for any application, tap the application. Next, set your own volume level according to listening mode:
With each listening mode, you can also adjust various items such as Media (multimedia volume), Ring (ringtone volume), Alarm ( alarm volume), Notifications (volume of notification messages) ), System (system volume). When you're done adjusting, you need to click on the floppy disk icon to save the changes.
