Low call volume on the vivo S50 can make conversations frustrating, especially in noisy environments. You might notice that even at maximum volume, voices still sound faint or unclear. This issue is usually tied to simple settings, speaker obstructions, or software behavior, and most fixes only take a few minutes to apply.
Why Your vivo S50 Call Volume Is Too Low
- Call volume is set low during an active call.
- The earpiece speaker is blocked by dirt, dust, or a phone case.
- Audio settings or sound enhancements are misconfigured.
- Software glitches after an update.
- Third party apps interfering with call audio.
1. Increase Call Volume During an Active Call
The call volume on vivo phones can only be adjusted while a call is ongoing. If you try changing volume outside a call, it will not affect call audio.
Make a phone call, and then press the Volume Up key repeatedly.
Watch the on screen indicator, and make sure call volume reaches the maximum level.
2. Check for Speaker Blockage
A partially blocked earpiece can significantly reduce call volume. Dust, lint, or even a thick screen protector can muffle sound without you noticing.
Inspect the earpiece area, and gently clean it with a soft brush.
Remove the phone case, and then make another test call to check the difference.
3. Disable Bluetooth and Wired Audio Devices
If your vivo S50 is connected to Bluetooth or wired audio, call sound may be routed elsewhere. This often makes it seem like the call volume is too low.
Open Settings, and then tap Bluetooth.
Turn Bluetooth off, and then place a test call to check the audio.
4. Check Sound and Audio Settings
Some sound enhancements can affect call clarity and loudness. Resetting or adjusting these options often improves voice volume instantly.
Open Settings, and then tap Sound and vibration.
Check any audio effects, and disable enhancements that may lower voice output.
5. Restart the Phone
Temporary software glitches can reduce call volume without warning. Restarting refreshes the audio system and clears background conflicts.
Press and hold the Power key, and then tap Restart.
Wait for the phone to boot up, and place a test call afterward.
6. Update the Phone Software
Outdated software may contain audio bugs that affect call volume. Installing updates ensures your phone has the latest fixes and optimizations.
Open Settings, and then tap System update.
Check for updates, and install any available version before testing calls again.
Low call volume on the vivo S50 is usually easy to fix once you pinpoint the cause. After adjusting settings, cleaning the speaker, or restarting the device, call audio should return to a comfortable level.
FAQs
Why is call volume low only on certain calls?
This can happen if the other person has a weak microphone or poor signal. Testing calls with different contacts helps confirm if the issue is on your phone.
Does a screen protector affect call volume?
Yes, if it partially covers the earpiece. Misaligned protectors can block sound and reduce call clarity.
Should I reset the phone if none of the fixes work?
If the problem persists after updates and basic fixes, contacting vivo support or your carrier is recommended before attempting a full reset.
