People cannot hear me when I make phone calls on my iPhone. Speakerphone works fine but the regular microphone does not.
If speakerphone works but regular calls do not, the bottom microphone (used for phone calls) is likely blocked or damaged while the speaker microphone (used for speakerphone and video) is fine. First, check for physical obstructions: look at the bottom of your iPhone next to the charging port — there are small microphone holes. Use a clean soft brush or a toothpick to gently clear any lint, dust, or debris from these holes. Do NOT use compressed air as it can push debris deeper. Next, check if a case or screen protector is covering the microphone. Remove the case and try a call. Also check your iPhone settings: go to Settings, Privacy & Security, Microphone, and make sure no call-related app is blocking microphone access. Try recording a voice memo — if the Voice Memos app picks up your voice clearly, the microphone hardware is fine and the issue is software. In that case, go to Settings, General, Transfer or Reset iPhone, and select Reset All Settings (this does not delete your data but resets network, display, and call settings to defaults). If the microphone truly does not work in any app, visit an Apple Store or authorized repair center — the microphone may need physical replacement, which costs about $60 to $80.
