Phones listen to what's going on around you. Imagine your phone is like a friendly robot that’s always watching and listening, it knows when you're on the phone, but it also notices if there are other people talking nearby. It checks for sounds that might mean another person is speaking, and if so, it decides whether to keep your phone loud or switch to silent mode.
Examples
- Your phone notices when your roommate starts talking during your call and switches to silent mode.
- If you're on a video call and another person walks into the room and starts speaking, your phone might quiet itself down.
- When your mom calls and your dad starts talking in the background, your phone might think it’s time for silent mode.
