Modern Samsung smartphones include a feature called "Separate App Sound," which allows users to direct audio from specific applications to different audio sources. This means users can play music from apps like YouTube Music through a Bluetooth speaker while keeping notification alerts routed through the phone’s built-in speaker. To enable this feature, users need to open the Settings app, tap on Sounds and vibrations, scroll to the bottom, select Separate app sound, toggle it on, choose the apps to configure, and decide the audio output for those apps. This feature was introduced with the Galaxy S8 series in 2017 and is often overlooked. It can enhance user experience by preventing interruptions from notifications during activities like hosting friends or driving. Other Android brands do not offer a similar functionality.
