Can’t Hear Calls on Android? Fix Earpiece and Call Audio Problems Safely

If you can hear music and videos normally but cannot hear the other person during a phone call, do not assume the phone’s main speaker has failed. Android call audio can use a different volume channel and output path from media audio, and the small receiver at the top of the phone can also be blocked even when the loudspeaker works normally.

This guide separates an earpiece problem from Bluetooth routing, Wi-Fi Calling, app interference and a broader speaker fault. Menu names vary by Android version, manufacturer, carrier and country, so use the closest equivalent on your device.

First identify exactly what is failing

Make a normal voice call and compare three states: the phone held to your ear, speakerphone enabled, and—if available—a known-good Bluetooth headset. If speakerphone works but the earpiece does not, focus on the receiver, its opening and in-call audio settings. If neither earpiece nor speakerphone works, check routing, accessibility settings, software and the network before treating it as hardware.

If the other person cannot hear you, that is a microphone problem rather than the issue covered here. If music, videos and notifications are also silent, use the site’s broader Android speaker troubleshooting guide.

1. Raise the volume while a call is active

Android keeps call volume separate from ringtone and media volume on many devices. Start a call, then press Volume Up several times while the call is connected. Changing volume from the Home screen may adjust a different audio channel.

Samsung’s current Galaxy support documentation specifically notes that in-call volume can only be adjusted while a call is in progress.

2. Check where the call audio is being routed

Disconnect wired accessories and temporarily turn Bluetooth off. During the call, check the audio or Bluetooth button and make sure the phone is not sending sound to earbuds, a car system, hearing device or another previously connected accessory.

If turning Bluetooth off immediately restores call audio, troubleshoot the accessory or Bluetooth connection rather than resetting the phone. See Bluetooth connected but no sound on Android for the next checks.

3. Test speakerphone

Enable Speaker during the same call. A working loudspeaker with a silent or extremely quiet earpiece is useful evidence: the cellular call itself is reaching the phone, but the receiver path may be obstructed, misconfigured or faulty.

If both outputs fail, continue with the software and network checks below.

4. Inspect the top earpiece, case and screen protector

Look closely at the narrow receiver opening near the top edge of the display. A badly aligned screen protector, protective film or case can partially cover it. Samsung identifies screen-protector obstruction as a cause of low or absent receiver audio on Galaxy devices.

Remove the case or film temporarily and test another call. If there is visible dust, clean only with a safe dry method recommended for your device. Do not push pins, liquid or adhesive into the opening.

5. Check accessibility audio settings

Some Android builds include a Mute all sounds option under Accessibility or Hearing enhancements. Confirm that it is disabled. Also check left/right audio balance if your phone exposes that control.

Settings paths differ substantially between Pixel, Galaxy and other Android interfaces, so search Settings for “mute all sounds,” “hearing” or “audio balance” if the menu is not where a manufacturer guide shows it.

6. Restart and install pending system updates

Restart the phone before making deeper changes. Then check for system and app updates through the manufacturer’s supported update path. A restart can clear a temporary audio-routing state, while current manufacturer guidance recommends updating software before further call-audio troubleshooting.

7. Compare cellular calling with Wi-Fi Calling

If the symptom is poor, broken or intermittent voice rather than a completely silent receiver, test a call with Wi-Fi Calling temporarily disabled. Samsung notes that a weak network connection used by Wi-Fi Calling can affect call quality. Availability and menu placement depend on the carrier, device and region.

If calls work correctly over cellular but fail over Wi-Fi Calling, investigate the Wi-Fi connection and carrier feature rather than the earpiece. If the reverse happens, carrier coverage or provisioning deserves attention.

8. Test Safe Mode when a downloaded app may be interfering

If the problem started after installing or updating an app, use your manufacturer’s documented Safe Mode procedure and make a test call. Safe Mode temporarily disables downloaded apps on many Android devices.

If call audio returns in Safe Mode, remove recently installed or updated apps one at a time after restarting normally. Avoid jumping straight to a factory reset; Safe Mode can provide much more useful evidence with far less disruption.

9. Separate a network problem from an audio-hardware problem

Call more than one number and, if practical, test in another location. If only one contact sounds bad, the problem may be at the other end. If calls consistently connect but the earpiece stays silent while speakerphone works, the evidence points more strongly toward the receiver path than the mobile network.

Conversely, dropped calls, robotic audio or failures that change with signal strength can indicate a network or Wi-Fi Calling issue. For broader connectivity symptoms, use the Android network and connectivity troubleshooting hub.

10. Use manufacturer diagnostics before considering a reset

Some manufacturers provide built-in diagnostics; Samsung, for example, offers device diagnostics through Samsung Members on supported Galaxy phones. If a receiver or speaker test reports a fault, service is a more rational next step than erasing the device.

A factory reset is destructive and should not be the first response to isolated call audio. Back up important data before any reset, and prefer manufacturer or carrier support when diagnostics indicate hardware trouble.

When the earpiece probably needs service

Hardware becomes more likely when the phone has suffered a drop or liquid exposure, the receiver remains silent across normal and Safe Mode, speakerphone works reliably, accessories and protective films are ruled out, and manufacturer diagnostics fail. Very low or distorted sound that does not change after safely clearing an obstruction can also justify inspection.

Bottom line

When you cannot hear calls on Android, start with the call-specific controls: raise volume during an active call, confirm the output route, compare earpiece with speakerphone, and inspect the receiver opening. Then test accessibility settings, restart, updates, Wi-Fi Calling and Safe Mode. Those comparisons usually tell you whether you are dealing with routing, software, the network or the physical earpiece without erasing the phone unnecessarily.
