When people cannot hear you during calls on your Xiaomi 15 Ultra, conversations become frustrating fast. Calls may connect normally, but your voice sounds muffled, very low, or completely silent. This issue is usually caused by microphone settings, software behavior, or simple hardware obstructions, and most fixes take only a few minutes.
Why People Can’t Hear You on Calls on Xiaomi 15 Ultra
- The microphone is blocked by dirt, dust, or a phone case.
- Call microphone permissions are disabled or limited.
- Noise reduction features are interfering with voice pickup.
- Bluetooth devices are connected and redirecting audio.
- Temporary software glitches affecting the phone app.
1. Check and Clean the Microphone
Your microphone must be clear to capture your voice properly. Even a thin layer of dust can significantly reduce call volume and clarity.
Inspect the bottom microphone area carefully.
Gently clean it using a soft brush or dry cloth, and then test a call.
2. Make Sure Microphone Permission Is Enabled
If the Phone app does not have microphone access, your voice will not transmit during calls. This often happens after system updates or permission changes.
Open Settings, and then tap Privacy protection.
Tap Permission manager, and then allow Microphone access for the Phone app.
3. Turn Off Bluetooth During Calls
Bluetooth devices can silently hijack the microphone, especially if a headset was connected earlier. This causes the phone to listen for audio from the wrong source.
Swipe down from the top right to open Control Center.
Tap Bluetooth to turn it off, and then place a test call.
4. Disable Call Noise Reduction
Noise reduction can sometimes suppress your voice instead of background sounds. Disabling it can immediately restore normal call volume.
Open Settings, and then tap Sound and vibration.
Tap Call settings, and then turn off Noise reduction or Voice enhancement.
5. Restart the Phone App and Device
Temporary system glitches can prevent the microphone from working correctly during calls. A restart refreshes all call-related services.
Open Settings, and then tap Apps.
Tap Phone, force stop it, and then restart your Xiaomi 15 Ultra.
6. Test the Microphone Using Recorder
Testing the microphone outside of calls helps confirm whether the issue is hardware or software related. If recordings sound clear, the problem is likely app or network based.
Open the Recorder app, and then record a short voice clip.
Play it back and check if your voice sounds normal.
If people still cannot hear you after these steps, the issue may be related to hardware damage or a carrier problem. In that case, contacting Xiaomi support or visiting an authorized service center is the best next move.
FAQs
Why can people hear me on speaker but not on regular calls?
Speaker mode often uses a different microphone. This usually points to a blocked or damaged primary call microphone.
Can a phone case cause microphone problems?
Yes. Thick or poorly designed cases can block the microphone opening and reduce voice clarity during calls.
Does a software update fix microphone issues?
In many cases, yes. Updates often include audio and call stability fixes, so keeping your Xiaomi 15 Ultra updated in 2025 is important.
