Fix a Problem
Why do some iPhone models play a sound during silent mode?
Unexpected iPhone sounds while Silent mode is enabled may come from app alerts, alarms, media, emergency alerts, or device-specific settings. Do not assume a hardware fault from one sound.
What to do
- Identify which app or event made the sound.
- Check Sounds & Haptics, the app's notification settings, and alarm schedules.
- Update iOS and test a repeatable scenario.
