When the speakerphone on your Xiaomi 15 Ultra stops working during calls, conversations become hard to hear and frustrating to manage. You may notice that tapping Speaker does nothing, or the sound stays low even at full volume. This issue is usually caused by audio routing problems, app conflicts, or simple settings that need a quick refresh.
Why the Xiaomi 15 Ultra Speakerphone Is Not Working
- The call audio is routed to another device like Bluetooth earbuds or a car system.
- The speaker grille is blocked by dirt, dust, or a tight phone case.
- A temporary system glitch is affecting call audio output.
- Call app permissions or settings are misconfigured.
- A recent update caused minor audio bugs that need a reset.
1. Make Sure Speakerphone Is Selected During the Call
Sometimes the call connects using the earpiece instead of the loudspeaker. This makes it seem like the speakerphone is broken when it is not.
Make a phone call, and then tap the Speaker icon on the call screen.
Increase the volume using the Volume Up key, and listen for sound from the bottom speaker.
2. Turn Off Bluetooth Connections
If your phone is connected to Bluetooth devices, call audio may be sent there instead of the speakerphone. This is one of the most common reasons speakerphone appears not to work.
Open Settings, and then tap Bluetooth.
Turn Bluetooth off, and then make another test call.
3. Restart the Phone
Restarting clears temporary system errors that can affect call audio. It refreshes the audio service and reconnects the speaker properly.
Swipe down from the top of the screen, and then tap the Power icon.
Tap Restart, and wait for the phone to turn back on.
4. Check Call App Permissions
If the Phone app does not have proper permissions, audio features may not function correctly. This can happen after updates or permission changes.
Open Settings, and then tap Apps.
Tap Manage apps, select Phone, and review Microphone and Speaker permissions.
5. Remove the Phone Case and Clean the Speaker
A blocked speaker grille can muffle sound or make it seem completely silent. Thick cases and dust buildup often cause this problem.
Remove the phone case, and then inspect the speaker area.
Gently clean the speaker grille using a soft brush, and try speakerphone again.
6. Test Speaker Output Using Sound Settings
Testing system sounds helps confirm whether the issue is limited to calls or affects the speaker itself. If system sounds work, the problem is likely software related.
Open Settings, and then tap Sound and vibration.
Adjust Media volume, and play a ringtone or system sound to test the speaker.
If your Xiaomi 15 Ultra speakerphone stops working, the fix is usually simple and quick. Once audio routing is corrected and basic settings are refreshed, speakerphone should work normally again during calls.
FAQs
Why does speakerphone work for music but not during calls?
This usually means the issue is limited to call audio routing or the Phone app. Checking permissions and Bluetooth connections often resolves it.
Can a software update break speakerphone on the Xiaomi 15 Ultra?
Yes. Minor audio bugs can appear after updates, but restarting the phone or resetting app permissions typically fixes the problem.
