When speakerphone stops working during calls, conversations become difficult fast. You may hear nothing, very low volume, or sound coming only from the earpiece even when speakerphone is on.
If this is happening on your Galaxy S25 Ultra, the issue is usually related to settings, audio routing, or app behavior rather than hardware damage.
Why Speakerphone Is Not Working on Your Galaxy S25 Ultra
- Speaker volume is set too low or muted during calls.
- Bluetooth audio is redirecting sound to another device.
- The Phone app has temporary glitches.
- Accessibility or sound settings are interfering with call audio.
- System software bugs are affecting audio output.
Check Speaker Volume During a Call.
Speakerphone may be working, but the volume is too low to hear. This is easy to miss because media volume and call volume are controlled separately.
- Make a call, and then tap the Speaker icon on the call screen.
- Press the Volume Up key several times, and then listen for audio changes.
If the sound suddenly becomes audible, the issue was simply call volume being turned down.
Turn Off Bluetooth Audio.
Your phone may still be connected to wireless earbuds, a car system, or a smartwatch. When this happens, speakerphone audio gets routed elsewhere.
- Open Settings, and then tap Connections.
- Tap Bluetooth, and then turn it off temporarily.
Make another call and test speakerphone again. If it works, reconnect Bluetooth later and check which device is set as the default audio output.
Restart the Phone App.
The Phone app can occasionally misroute call audio. Restarting it clears temporary glitches without affecting your data.
- Open Settings, and then tap Apps.
- Tap Phone, and then tap Force stop.
After that, place a new call and test the speakerphone function again.
Disable Hearing Enhancements or Accessibility Audio Features.
Certain accessibility options can change how call audio is processed. This may interfere with speakerphone behavior.
- Open Settings, and then tap Accessibility.
- Tap Hearing enhancements, and then turn off any active audio features.
Lock the screen, make a call, and test speakerphone once more.
Update the System Software.
Audio issues are sometimes caused by bugs in the system software. Updates often include fixes for call and speaker problems.
- Open Settings, and then tap Software update.
- Tap Download and install, and then follow the on-screen instructions.
After updating, restart your Galaxy S25 Ultra before testing speakerphone again.
Reset App Preferences.
If another app is interfering with call audio, resetting app preferences can help without deleting personal data.
- Open Settings, and then tap Apps.
- Tap the menu icon, and then tap Reset app preferences.
This restores default app behaviors and often resolves speakerphone issues caused by misconfigured permissions.
Speakerphone problems on the Galaxy S25 Ultra are usually fixable with a few setting checks. Once audio routing is restored, calls should play clearly through the main speaker again.
FAQs
Why does speakerphone work for media but not for calls?
Call audio uses a different audio channel than media. If call volume is low or Bluetooth is active, speakerphone may appear broken even though the speaker itself works.
Can a screen protector or case affect speakerphone sound?
Yes. Thick cases or poorly fitted screen protectors can partially block the speaker grill, reducing volume during calls.
Does resetting app preferences delete apps or data?
No. It only resets default app settings and permissions. Your apps and personal data remain untouched.
