If your vivo S50 speakerphone suddenly stops working during calls, you may not hear anything once you switch to loudspeaker mode. That can be frustrating, especially when you are in a meeting, driving, or sharing the call with someone nearby. In most cases, the issue is caused by simple settings, call audio glitches, or software restrictions.
Here is how you can fix it.
Why Your vivo S50 Speakerphone Is Not Working
- The call audio output is not switching to loudspeaker properly.
- Bluetooth is connected and routing audio elsewhere.
- Dirt or blockage in the speaker grille.
- Third-party apps interfering with call audio.
- Minor system bugs affecting the phone app.
Restart Your Phone
A quick restart refreshes the phone app and resets the audio system. This often fixes temporary call routing issues.
Press and hold the Power key, and then tap Restart.
Wait for the device to boot up, and then make a test call.
Switch to speaker mode again during the call and check if audio works.
Make Sure Bluetooth Is Turned Off
If Bluetooth is connected to earbuds or a car system, call audio may be redirected. The speakerphone will not work until Bluetooth is disconnected.
Open Settings, and then tap Bluetooth.
Turn off Bluetooth, and then make a test call.
Switch to speaker mode and see if the sound comes through the main speaker.
Check the Call Audio Output
Sometimes the phone does not switch audio correctly during calls. You can manually verify the output option.
Make a call, and then tap the Speaker icon.
If available, tap Audio output, and then choose Speaker.
Listen carefully to confirm that sound is coming from the loudspeaker.
Remove Phone Case and Clean the Speaker
Dust or a tight phone case can block the speaker grille. This may make it seem like the speakerphone is not working.
Remove the phone case, and then inspect the bottom speaker area.
Gently clean the grille using a soft brush, and then test the speaker again.
Make another call and switch to speaker mode.
Clear the Phone App Cache
Corrupted temporary files in the dialer app can cause audio problems. Clearing the cache refreshes the app without deleting your data.
Open Settings, and then tap Apps.
Tap Phone, and then tap Storage.
Tap Clear cache, and then restart the phone before testing again.
Check for Software Updates
Software bugs can sometimes affect call functions. Installing updates ensures your device has the latest fixes.
Open Settings, and then tap System update.
Tap Check for updates, and then install any available update.
After updating, restart the device and test the speakerphone again.
If your vivo S50 speakerphone is not working during calls, the issue is usually related to audio routing, Bluetooth interference, or minor software glitches. Once you restart the phone, disable Bluetooth, or refresh the Phone app, the speaker function should return to normal.
FAQs
Why can I hear music but not calls on speakerphone?
This usually means the media speaker is working, but call audio routing is stuck. Restarting the phone or clearing the Phone app cache often resolves this.
Can a damaged speaker cause this issue?
Yes. If there is no sound at all during calls and media playback, the loudspeaker hardware may be faulty and require service.
Why does my speakerphone work sometimes and not other times?
Intermittent issues are often caused by Bluetooth auto-connect features or temporary system glitches. Turning off Bluetooth and restarting the device usually stabilizes it.
