Galaxy S20 no sound. Here’s how to fix it!

This post will help you resolve a problem on the Galaxy S20 with no sound. Try these simple tweaks before opting for service.

Audio problems in mobile devices can either be due to a software malfunction if not faulty hardware like a busted audio component. The solutions I’ve mapped in this post are intended to eliminate software-related factors that might have ruined the audio system and caused the no sound problem.

When sound problems arise, that could be that the speaker is not functioning or the phone might be stuck in headphone mode. In most cases though, software-related factors appeared to be the underlying cause. This is usually what’s transpiring in new devices that suddenly loses audio for calls, apps, music and other features.

Troubleshooting Galaxy S20 with no sound

Time Needed : 10 minutes

Before you begin troubleshooting, check and ensure that the volume is not set to the lowest. The fastest way to check is by pressing the volume up or down keys on the side of the phone. Considering the placement of the physical volume keys, it’s very possible for the phone’s volume to be lowered unintentionally. Thus, it’s imperative to check your phone’s volume level beforehand. If pressing the Volume Up key doesn’t yield a positive result, try these subsequent methods.

  1. Toggle the ringer switch off and on.

    When an app suddenly goes rogue, it usually encounters an error and therefore needs a quick refresh. If this is what happened to your phone’s audio system, then turning the audio off and on could help. Thus, turning silent mode on and off is the first recommended solution.
    To enable and disable silent mode, access the notification panel by swiping down from the top of the Home screen. On the panel you will see the Audio icon next to the Wi-Fi icon. Tap that Audio icon to enable silent mode and mute the phone. After a few seconds, tap the same icon to disable silent mode and put the phone back to ring mode.
    Alternatively, press the Volume Down key until it reaches the lowest level. After a few seconds, press the Volume Up button several times to increase the volume level, if necessary. 
    When you press the Volume Up key, you will see the volume slider on the upper portion of the display.

  2. Restart the phone.

    Random issues inflicted by minor software errors are usually remedied by a simple restart on the phone. Aside from giving your device a pause, it also clears and refreshes the internal memory, clearing out erroneous cached audio files. 
    You can carry out the usual reboot (soft reset) or execute a force restart on your Galaxy S20. Both methods often render positive outcomes, when dealing with minor system flaws.
    To soft reset the Galaxy S20, press and hold the Bixby/Power button and then tap Restart from the given options. The phone will then shutdown and reboot on its own.
    To force restart the Galaxy S20, press and hold the Bixby/Power button and Volume Down key simultaneously for about 45 seconds. Then release both keys when the Samsung logo appears.
    Allow your phone to execute system startup and load up the Home screen. 
    A force-restart is usually needed if the phone seemed stuck on headphone mode.
    By then you can test to see if the audio is already working properly. You can use a sound-enabled app, place a test call, or send a message to your phone to see if you can hear the notification sounds.
    Restarting does not affect any saved information on the internal memory, and so it doesn’t need backup creation.

  3. Disable all Bluetooth connections.

    If your phone is currently connected or paired with a Bluetooth-enabled device, you may not hear any sound coming from the speaker. The Bluetooth connection might have been activated and so all sounds from the built-in speaker are bypassed to its paired Bluetooth device or accessory. To clear this out, turn off Bluetooth on your phone settings.
    To do this, navigate to Settings-> Connections-> Bluetooth menu and then toggle the switch to turn Bluetooth off.
    Another way to disable Bluetooth connections and other wireless features is by enabling Airplane mode or Flight mode.
    All current Bluetooth connections are then deactivated.

  4. Restore default settings (Reset all settings).

    Performing this reset is usually needed when the initial procedures failed to solve the problem. Like any other Samsung devices, the Galaxy S20 also has different types of reset commands you can use. 
    To reset all current system settings without deleting any saved information, the Reset settings command is an option. Doing so will erase all current system settings including customized information, without affecting the internal data. 
    To reset settings on the Galaxy S20, navigate to Settings-> General management-> Reset menu and then choose the option to Reset settings.
    All customized settings on your phone will then be deleted but personal information won’t be affected.
    If prompted, read and review the reset settings information then tap the Reset settings button to proceed. Finally, tap Reset to confirm that you’d like to proceed with the settings reset.
    After the reset, restart  your phone to apply the recent changes.  When it’s done rebooting, enable necessary features individually so that you can use them again on your phone.
    This reset is recommended before opting for a factory data reset. If this doesn’t solve the problem, then this is when you should consider opting for a full system reset or master reset.

  5. Factory reset/Master reset.

    Problems that could not be remedied by the previous methods are usually due to some complex system errors, if not, hardware damage. To rule out system errors from the underlying cause, you can carry out a factory data reset or master reset on your Galaxy S20.
    This reset will wipe all data from your phone including saved information and thus, creating backups of critical information is highly recommended beforehand. 
    Once you have secured the backup, go to your phone Settings-> General management-> Reset menu and then choose Factory data reset from the given options. On the next screen, scroll down and tap Reset then Delete all to confirm that you’d like to erase your device.
    After the reset, all settings are restored to defaults. That said, you will need to re-enable individual features and services that you’d like to use on your device.

The above procedures are usually enough to clear out software-related factors that caused no sound problem on the galaxy s20. If none of them works, then there’s a higher chance that your phone is enduring some sort of physical or liquid damage. At this point, seeking a technician’s aid is recommended. 

If your phone is still under warranty, contact your phone provider/carrier and avail for warranty instead.
