Permissions, mute state, and one test in another app usually tell you faster than a full reset.
Check permissions and mute state
Many audio and camera issues come from one blocked permission or routing choice.
Test in a second app
If the feature works there, the problem is probably app-specific.
Disconnect accessories
Bluetooth devices and USB accessories can quietly steal audio or camera control.
Update and restart
A small restart after permissions and accessory cleanup often resets the media path.
Reset only the relevant settings
Do this last if the mic, speaker, or camera still fails everywhere.
- The issue survives every basic step
- The problem is getting worse instead of better
- You may be dealing with a hardware fault or service-side outage
