This post will help you troubleshoot a low audio problem on Galaxy S20 during calls. Feel free to try these quick solutions before taking a trip to a service center.
Audio problems during phone calls from low to no audio are usually attributed to some settings that aren’t properly configured. Or it could simply because of the volume control/level that’s set to lower or lowest level. In worst case scenarios, audio problems can be directly attributed to hardware damage like a dysfunctional speaker, microphone or other audio components.
Mapped out below are recommended workarounds and potential solutions to a similar issue on the new Samsung galaxy s20. Here’s a quick guide on how to deal with a problem on the Galaxy S20’s low audio outputs during phone calls.
Troubleshooting a Galaxy S20 problem on low audio during calls
Time Needed : 10 minutes
Before you proceed, press the Volume Up key several times to increase the volume level, if needed. This will rule out the very obvious possibility about the phone’s volume that’s set to a lower level. If pressing the Volume Up key doesn’t do any good and you’re still facing the same low audio problem during phone calls, try the following methods to eliminate software-related factors from the underlying cause.
- Restart the phone (soft reset).
If everything was working perfectly fine then suddenly you’re having trouble hearing phone call audio, it’s probably just a random glitch transpiring on the phone’s audio system. To clear out minor flaws like this, restarting the phone can help.
To restart the phone, just press and hold the Power/Side and Volume Down buttons for a few seconds then tap the Restart icon.
A restart or soft reset on the phone can help fix various types of software-related issues and thereby clears out any associated random audio symptoms that might have caused low audio during phone calls.
- Turn Ringer switch off and on.
Random sound issues can also be remedied by switching the ringer switch off for a few seconds and then turn it back on again. It’s like giving the system a quick refresh.
To access and toggle the ringer switch, just open the notification panel then tap the Sound icon. It’s the second icon lined up in the notification panel, right next to the Wi-Fi icon. Tapping this icon will turn the ringer off or on. If the icon is greyed out, it means that it’s turned off and thus your phone is muted. If the icon is blue or highlighted, it means that the feature is turned on and ring mode is active.
Launching the notification panel is done by swiping down from the top of the screen.
- Check and manage Sound settings.
Some controls and relevant settings on the phone might haven’t been properly configured and thus this results in low audio. To clear this out, check and manage the sound controls straight from the sound settings menu on the phone.
To access and manage sound settings on your Galaxy S20, go to Settings-> Sounds and vibration-> Volume menu then adjust the volume level for the ringtone, media, notifications, and system. To make necessary adjustments, simply drag the slider from left to right to increase the audio level or left to decrease.
Also consider checking if the media volume limit is enabled on your device. To access this setting, simply tap the quick Menu icon (triple dots) located on the top-right corner of the Volume screen then tap Media volume limit. On the Media volume limit switch is turned on, the custom volume limit is enabled and could be the main reason why the sound is low when using headphones and Bluetooth audio devices during phone calls. In that case, just toggle the switch to turn the feature OFF.
You can also enable the option to Use Volume keys for media to control the media volume by default when you press the Volume keys.
- Disable Bluetooth connections.
If your phone is currently paired or connected to a Bluetooth accessory, it’s sound will be routed to the Bluetooth device. As a result, you won’t hear a sound coming from the built-in speaker. To rule this out, disconnect all Bluetooth connections by disabling the phone’s Bluetooth function.
To disable Bluetooth, go to Settings-> Connections-> Bluetooth menu and then toggle the switch to turn Bluetooth off.
Turning Bluetooth off will disconnect your Galaxy S20 from any nearby Bluetooth devices and thereby rules out the possibility that the sound output is routed to a Bluetooth-enabled accessory that’s paired with your phone.
- Install new firmware updates, if available.
Should the problem be inflicted by some system bugs and errors, installing the latest firmware update will likely fix it. Software updates not only bring in new features but also deliver fix patches to address system issues caused by stubborn bugs.
To check for new updates, just go to Settings-> Software update menu then tap Download and Install. Wait for your phone to check for updates and download the latest firmware version available.
Make sure that your phone is sufficiently charged and has a stable internet connection. When the update is completely downloaded, tap the Install Now button. Doing so will prompt the device to install the new update.
Typically, the phone will restart automatically after the update is installed, so just wait patiently until it’s finished rebooting.
Then try to place a test call to your Galaxy S20 to check and see if the low audio problem is gone already.
- Android 10, One UI 2.0 and up
- Galaxy S20, Galaxy S20 Plus, Galaxy S20 Ultra
If none of the given solutions is able to fix the problem on low audio during phone calls, this is the point when you should consider taking the phone to a service center. What you’re dealing with is more likely hardware-related and therefore needs some physical repair. If your phone is still under warranty, then availing for warranty would be a better option. Depending on the actual condition of the device, you may be able to avail warranty for service or new unit replacement. Talk to your phone provider/carrier for further inquiries on warranty offers.
