Then get the Xposed Installer application downloaded and installed on your device. Then launch the Xposed Installer app and you will find some information with the framework, modules, and other such options.
Just tap on the Framework option which will open a new menu, then tap on the install/update option. Then it will show a superuser request that needs permission from you which you need to simply grant.
It will install the framework in the background and you just need to wait until you see a new pop-up screen, then tap on ok.
Now finally to help the changes to take effect perfectly, you can simply reboot your device and when you restart your device, you will be able to operate or control music with volume keys.
We hope this process that finally lets you control music with volume keys with the help of the Xposed Installer app helped you.
