Samsung How to Turn On/Off Mono audio

With headphones, the sound is usually reproduced in stereo. This means that the sound is reproduced on two different audio channels, with each audio track being heard on one auricle at a time, giving a complete picture only in our ears.

For example, if we share headphones or are deaf in one ear, the Samsung device can switch from stereo to mono audio, and mono audio means that only one audio channel is played, so the output is the same in each ear.
