Something as simple as adding a panel to adjust the volume on an Android device can be a nightmare.
Most of the time, you need to go through a technical process called "rooting". Noyze Volume Panel keeps things simple with a Google Play Store download and delivers a useful program which can help you manage all the apps that are making noise.
Each app is displayed with an individual volume bar. The panel itself can be accessed by swiping down or tapping the volume buttons on your device.
