When people cannot hear you during calls on your OnePlus 15, conversations quickly become frustrating. You may sound muffled, extremely quiet, or completely silent, even though everything else seems fine. In most cases, this problem is caused by microphone settings, software behavior, or simple physical obstructions, and it can usually be fixed without professional repair.
Why People Can’t Hear You on Calls on the OnePlus 15
- The microphone opening is blocked by dust, dirt, or a phone case.
- Call microphone access is disabled for the Phone app.
- Bluetooth audio is redirecting your voice to another device.
- Noise cancellation or call settings are interfering with voice pickup.
- Temporary software glitches affecting the microphone system.
1. Clean and Check the Microphone Openings
The OnePlus 15 uses multiple microphones to capture your voice clearly. If any of them are blocked, your voice may sound faint or not transmit at all.
Take a close look at the bottom and top edges of the phone.
Gently clean the microphone holes using a soft brush or dry cloth.
Remove the phone case temporarily and test a call again.
2. Make Sure the Phone App Has Microphone Access
If microphone permission is disabled, your voice will not be transmitted during calls. This can happen after system updates or permission changes.
Open Settings, and then tap Privacy.
Tap Permission manager, and then tap Microphone.
Select the Phone app and make sure microphone access is allowed.
3. Turn Off Bluetooth and Test a Call
Sometimes your voice is routed to a connected Bluetooth device without you noticing. This makes it seem like the microphone is not working on the phone itself.
Swipe down from the top of the screen to open Quick Settings.
Tap Bluetooth, and then turn it off.
Make a test call and check if the other person can hear you clearly.
4. Disable Noise Cancellation or Call Enhancements
Call enhancement features can occasionally interfere with how your voice is captured. Turning them off helps determine if they are causing the issue.
Open Settings, and then tap Sound and vibration.
Tap Call settings, and then look for noise reduction or call enhancement options.
Turn these features off and place another call.
5. Restart the OnePlus 15
A restart refreshes system services, including audio and microphone processes. This often fixes temporary software issues that affect call audio.
Press and hold the Power key until the power menu appears.
Tap Restart, and then wait for the phone to boot up completely.
Test your microphone again during a call.
6. Test the Microphone Using Voice Recording
Before assuming a hardware problem, it is important to confirm whether the microphone works at all. Voice recording apps provide a quick way to test this.
Open the Recorder app, and then start a new recording.
Speak normally for a few seconds and stop the recording.
Play it back and check if your voice sounds clear and loud.
If people still cannot hear you after trying these steps, the issue may be hardware related or linked to your carrier. At that point, contacting OnePlus support or your network provider is the best next step.
FAQs
Why can people hear me on speakerphone but not on regular calls?
This usually means one microphone is working while another is blocked or malfunctioning. Cleaning the phone and checking call settings often resolves this.
Can a software update cause microphone issues on the OnePlus 15?
Yes. Updates can sometimes change permissions or audio behavior. Restarting the phone and checking microphone access usually fixes it.
Should I reset my phone if the microphone still does not work?
If all troubleshooting steps fail and recordings are silent, a factory reset or service inspection may be necessary, especially if hardware damage is suspected.
