■ Troubleshooting
When app is on the background (device is locked, home screen is on), volume can be controlled only on few devices.
1) For android devices
- Volume can be controlled with +/- keys for Lollipop (Android 5.x) or higher.
(Unavailable for Kitcat(Android 4.4.x) or earlier versions)
2) For iOS devices
- Volume +/- keys can be used.
(Speaker volume control on lock screen and alarm screen do not make much difference)
