If people cannot hear you during phone calls on your vivo X300 Pro, conversations quickly become frustrating. You may hear the other person clearly, but your voice sounds faint, distorted, or completely silent on their end. This issue is usually related to microphone access, settings, or simple hardware obstructions, and most of the time it can be fixed in just a few minutes.
Why People Can’t Hear You on Calls on the vivo X300 Pro
- The microphone is blocked by dirt, dust, or a phone case.
- App permissions are preventing the Phone app from using the microphone.
- Call settings or network issues are interfering with voice transmission.
- Bluetooth is connected to another device, redirecting the microphone.
- Temporary software glitches affecting the audio system.
1. Check the Microphone Openings
The vivo X300 Pro has multiple microphones, and even a small blockage can affect call quality. Dust, lint, or a tight case can prevent your voice from being picked up properly.
Inspect the microphone holes at the bottom and near the camera.
Remove any case or screen protector, and gently clean the openings using a soft brush or compressed air.
Make a test call to see if your voice sounds clearer.
2. Make Sure the Phone App Has Microphone Access
If microphone permission is disabled, your phone cannot transmit your voice during calls. This can happen after a software update or permission reset.
Open Settings, and then tap Privacy.
Tap Permission manager, and then tap Microphone.
Find Phone, and make sure microphone access is set to Allow.
3. Turn Off Bluetooth Temporarily
Bluetooth devices like earbuds or car systems can take over the microphone without you realizing it. When this happens, the phone’s built-in microphone is not used.
Swipe down from the top of the screen to open Quick Settings.
Tap Bluetooth to turn it off, and then make a call again.
If your voice works, reconnect Bluetooth only when needed.
4. Test the Microphone Using Voice Recorder
Testing the microphone helps confirm whether this is a hardware or software issue. If recordings sound clear, the problem is likely related to call settings or the network.
Open the Voice Recorder app, and then start a new recording.
Speak normally for a few seconds, and then play the recording back.
If your voice is faint or missing, the microphone may be faulty.
5. Restart the Phone
A restart refreshes system services and clears temporary audio bugs. It is a simple step that often fixes call-related issues instantly.
Press and hold the Power button, and then tap Restart.
Wait for the phone to turn back on, and then place a test call.
Check if the other person can hear you clearly.
6. Reset Network Settings
Network configuration problems can interfere with voice transmission during calls. Resetting network settings restores all call-related connections to default.
Open Settings, and then tap System.
Tap Reset options, and then tap Reset network settings.
Confirm the reset and test calls again after the phone reconnects.
If people still cannot hear you after trying these steps, the issue may be related to a damaged microphone. At that point, professional service or support may be required, especially if the phone was recently dropped or exposed to moisture.
FAQs
Why can people hear me on speaker but not on normal calls?
This often indicates that one microphone is working while another is blocked or damaged. Speakerphone uses a different microphone than regular calls.
Can a phone case cause microphone problems?
Yes. Thick or poorly designed cases can partially block microphone openings, leading to muffled or missing audio during calls.
Should I update my vivo X300 Pro if call audio is not working?
Yes. Software updates often fix audio and call-related bugs. Installing the latest update can improve microphone performance and call stability.
