Echo or feedback during calls:

• Use headphones or earbuds to prevent speaker feedback

Background noise issues:

iPhone Microphone Locations

iPhones have multiple microphones for different purposes:

• Bottom microphone: Primary mic for calls and recordings (next to Lightning/USB-C port)
• Front microphone: Near the earpiece, used for FaceTime and noise cancellation
• Rear microphone: Near the camera, used for video recording

Make sure all microphone openings are clean and unobstructed.

Testing Microphone Hardware

1. Open Voice Memos and record a message
2. Record a video using the Camera app and play it back
3. Make a FaceTime audio call
4. Use Siri (hold Side button or say "Hey Siri")

If none of these work, you may have a hardware issue and should contact Apple Support or visit an Apple Store.
