If the speakerphone on your vivo X300 Pro stops working during calls, conversations can quickly become frustrating. You might tap the speaker icon and hear nothing, or the call audio may still come through the earpiece instead of the loudspeaker.
In most cases, this issue is caused by simple settings, temporary system glitches, or audio conflicts from apps. The good news is that you can usually fix it in just a few minutes.
Why the Speakerphone Is Not Working on vivo X300 Pro
- Temporary audio glitches after long uptime
- Call audio routed to a Bluetooth device instead of the speaker
- Dirt or obstruction blocking the speaker grille
- System bugs affecting call audio services
- Third party apps interfering with microphone or speaker access
1. Restart Your Phone
A restart refreshes the audio services that control the speaker, microphone, and call routing. If the problem is caused by a temporary software glitch, rebooting the phone often restores the speakerphone immediately.
Press and hold the Power button, and then tap Restart.
Wait for the phone to reboot, and then place a test call.
Tap the Speaker icon during the call, and check if audio plays through the loudspeaker.
2. Make Sure Bluetooth Is Turned Off
If your phone is connected to wireless earbuds, a headset, or a car system, the call audio may be routed there instead of the phone speaker. Turning off Bluetooth ensures the call audio stays on your device.
Open Settings, and then tap Bluetooth.
Toggle Bluetooth off, and then return to the call screen.
Start another call and tap Speaker to test the audio.
3. Check If the Speaker Is Blocked
Dust, lint, or a thick phone case can partially block the loudspeaker. When this happens, the speakerphone may sound extremely quiet or appear to stop working during calls.
Inspect the bottom speaker grille, and then remove any debris gently.
Remove your phone case, and then place another call.
Tap Speaker during the call to check if the volume improves.
4. Increase the Call Volume
Sometimes the speakerphone is actually working, but the call volume is set too low. Increasing the volume ensures the loudspeaker produces audible sound during calls.
Start a phone call, and then tap the Speaker icon.
Press the Volume Up button, and then raise the call volume to the maximum level.
5. Check App Permissions for the Phone App
Certain system permissions allow the phone app to control audio hardware properly. If these permissions are restricted, the speakerphone feature may not behave correctly.
Open Settings, and then tap Apps.
Tap Phone, and then tap Permissions.
Make sure Microphone access is enabled, and then try another call.
6. Reset App Preferences
Resetting app preferences restores default settings for system apps without deleting your data. This can fix conflicts that prevent the speakerphone from activating.
Open Settings, and then tap Apps.
Tap the three dot menu, and then select Reset app preferences.
Confirm the reset, and then restart your phone.
If your vivo X300 Pro speakerphone still refuses to work after trying these fixes, the issue may be related to hardware. At that point, contacting vivo support or visiting a service center would be the best next step.
FAQs
Why does my vivo X300 Pro speakerphone work for music but not during calls?
This usually happens when call audio is routed to another device such as Bluetooth earbuds. Turning off Bluetooth or disconnecting other audio devices often resolves the problem.
Can a software update fix speakerphone problems?
Yes. System updates often include bug fixes for audio drivers and call services, so installing the latest update can restore normal speakerphone functionality.
How do I test if my phone speaker is damaged?
Play music or a video at full volume. If the sound is clear, the speaker hardware is likely fine, and the issue is probably related to call settings or software.
