Limiting the volume
You can use AVLS (Automatic Volume Limiter System) to limit the maximum volume. This prevents the volume from getting too high and disturbing others, causing discomfort to your ears, or preventing you from hearing sounds around you, and it allows you to listen at a more comfortable volume.
Swipe the status bar down and tap - [SETTINGS].
Tap [ Sound] - [AVLS (Volume Limit)].
