How to Fix OnePlus 13 People Can’t Hear Me on Calls

If people can’t hear you during phone calls on your OnePlus 13, it can make conversations frustrating and confusing. Whether your voice sounds faint, muffled, or doesn’t come through at all, the problem could be caused by software glitches, microphone blockage, or incorrect settings.

The good news is that this issue is usually easy to fix. Try the following solutions to restore clear audio during your calls.

Why People Can’t Hear You on Calls on OnePlus 13

• Microphone holes are blocked or dirty.
• A Bluetooth headset is connected accidentally.
• Noise cancellation settings are interfering.
• Outdated software or app bugs.
• Third-party apps are using the microphone in the background.

Check for Blocked Microphones.

The OnePlus 13 has multiple microphones for calls and noise cancellation. If any are blocked, sound may not transmit clearly.

1. Inspect the bottom and top edges of your phone for dust or debris.
2. Use a soft brush or compressed air to gently clean the openings.

Avoid inserting sharp objects that could damage the microphone mesh.

Disconnect Bluetooth Devices.

Your phone may be routing call audio through a Bluetooth headset or speaker. Disconnecting ensures that sound goes through the built-in microphone instead.

1. Open Settings, and then tap Bluetooth.
2. Turn off Bluetooth, or manually disconnect paired devices.

Make a test call to check if the issue is resolved.

Turn Off Noise Cancellation.

The noise cancellation feature reduces background sounds but can sometimes affect voice clarity. Turning it off can help if callers say you sound distant.

1. Open Settings, and then tap Sounds and vibration.
2. Tap Noise cancellation, and then toggle it off.

Try another call to see if your voice becomes clearer.

Test the Microphone.

Testing helps you confirm if the microphone itself is working properly. You can use the Recorder app for this.

1. Open the Recorder app, and then record a short clip speaking normally.
2. Play it back and listen for clarity.

If the recording is faint or silent, it may be a hardware issue.

Update the Phone Software.

Microphone and audio issues can sometimes come from software bugs. Keeping your OnePlus 13 up to date helps fix these glitches.

1. Open Settings, and then tap About device.
2. Tap OxygenOS version, and then select Check for updates.

If an update is available, download and install it, then restart your phone.

Reset App Preferences.

Sometimes, third-party apps or permission changes cause conflicts with the microphone. Resetting app preferences can help.

1. Open Settings, and then tap Apps.
2. Tap App management, and then select Reset app preferences.

This restores all app permissions to default without deleting your data.

If the problem continues, it could indicate a deeper hardware issue. In that case, contact OnePlus Support or visit an authorized service center for diagnosis.
