If people keep saying they cannot hear you during calls on your vivo S50, the problem is usually related to the microphone or call settings. Sometimes your voice sounds faint, muffled, or completely silent on the other end. The good news is that this issue is often caused by simple settings or temporary glitches that you can fix in minutes.
Why Your vivo S50 Microphone Is Not Working Properly
- The microphone opening is blocked by dirt or a case.
- Microphone permission is disabled for the Phone app.
- Noise reduction settings are interfering with voice pickup.
- Bluetooth devices are connected and taking over the microphone.
- A temporary software glitch is affecting call audio.
1. Check for Microphone Blockage
The microphone hole on the bottom of the vivo S50 can easily collect dust. Even a thin layer of dirt can reduce voice clarity.
Inspect the bottom edge of your phone, and locate the small microphone hole.
Gently clean it using a soft brush or compressed air.
Remove any thick phone case, and then test a call again.
2. Restart Your Phone
A simple restart refreshes audio services and clears temporary system glitches. Many call audio issues disappear after a reboot.
Press and hold the Power button, and then tap Restart.
Wait for the phone to boot up completely, and then make a test call.
Check if the other person can now hear you clearly.
3. Check Microphone Permissions
If the Phone app does not have microphone access, your voice will not be transmitted during calls. This can happen after app updates or privacy changes.
Open Settings, and then tap Apps.
Tap App management, and then select Phone.
Tap Permissions, and then make sure Microphone is allowed.
4. Turn Off Bluetooth
If Bluetooth earphones or a car system are connected, your phone may route the microphone through that device. This makes it seem like the phone mic is broken.
Swipe down to open Quick Settings, and then tap Bluetooth to turn it off.
Make a call directly from the phone, and check the audio quality.
If the issue disappears, the problem was caused by a connected device.
5. Test the Microphone Using Voice Recorder
Testing the microphone helps determine if the issue is hardware related. If your recording sounds clear, the microphone is working properly.
Open the Recorder app, and then start a new recording.
Speak normally for a few seconds, and then play the recording back.
If the sound is distorted or silent, there may be a hardware issue.
6. Update Your Software
Software bugs can sometimes affect call audio performance. Installing the latest update may fix compatibility or stability issues.
Open Settings, and then tap System update.
Tap Check for updates, and install any available update.
Restart the phone after updating, and test your calls again.
Call audio problems on the vivo S50 are usually caused by blocked microphones, permission settings, or Bluetooth conflicts. Once you isolate the cause and apply the correct fix, your calls should return to normal quickly.
FAQs
Why can people hear me on speaker but not on regular calls?
This often means the primary microphone is blocked or malfunctioning. Speaker mode may use a secondary microphone, which is why your voice becomes clearer.
Can a screen protector affect call audio?
A poorly installed screen protector usually does not affect the microphone, but a thick phone case can block the bottom mic opening.
How do I know if my microphone is damaged?
If voice recordings are silent or heavily distorted even after cleaning and restarting, the microphone may be physically damaged and require service.
