Volume Panel Free

The default volume panel in Android is not all that helpful, especially if you need to make different changes at the same time. With an app such as the Volume Panel Free, users can access all the options without having to open the settings panel.
 
The application is a floating overlay that features a left-handed option, custom vertical position, a custom panel timeout, custom background, the option to exclude from certain applications, and different volume streams for Cast, Media, Ring, Call & Alarm.
 
Also, users can switch to the speaker when in a call, and they can even create a shortcut on the Home screen, in newer Android versions, including Oreo.
