Pinterest LinkedIn Tumblr

To pair and use a Bluetooth device with your Samsung Galaxy S20, you know that both devices need to be compatible and within close proximity. However, even when these requirements are met, you may encounter situations where your Bluetooth device keeps disconnecting from your smartphone.

The issue of Bluetooth devices keep getting disconnected from your Samsung Galaxy S20 could occur due to one or a few causes, such as:

  • Issues with the Bluetooth service on your Galaxy S20. 
  • A software or hardware problem with the Bluetooth device itself.
  • An issue with the Android software that disconnects the Bluetooth device from your Galaxy S20.
  • Or a hardware failure of the Bluetooth module on your Galaxy S20.

In this guide, we have provided 07 solutions with detailed explanations and step-by-step instructions to help you troubleshoot and resolve this problem. Let’s get started!

Note: Solutions in this guide will work on any Samsung Galaxy S20 model (S20, S20 Plus, S20 Fe, and S20 Ultra models.)

Editor’s note: We created these instructions using a Samsung Galaxy S20 running Android 13. Depending on your device’s software version, some steps and menu positions may look slightly different.

Fix 01: Restart Both Devices

Restarting both your Samsung Galaxy S20 and the Bluetooth device will clear any temporary software glitches that may have developed over time causing the disconnection. Therefore you should start the troubleshooting process by restarting both devices.

Follow these steps to correctly restart your Samsung Galaxy S20:

  1. Press and hold the Power button and the Volume Down button together and wait about 15 seconds until you see the Samsung logo appear on your screen. Then release the buttons.

To restart your Bluetooth device, refer to the device’s user manual for accurate instructions as the restart process will vary depending on the specific device. 

Once both devices have been restarted, connect them again. Then check if the Bluetooth device maintains a stable connection with your Galaxy S20.

Fix 02: Check the Battery Level of the Bluetooth Device

Bluetooth devices are powered by small batteries. Since these batteries carry lower capacity, a technology called “Bluetooth Low Energy” (BLE) is used when designing these devices to consume minimal power. 

However, if the battery level of the Bluetooth device is really low, it will struggle to keep the connection, leading to persistent disconnections.

To ensure that this isn’t the case, check the battery level of your Bluetooth device. If it’s low, charge it to its full capacity before reconnecting it to your Galaxy S20. You can check the battery level of your Bluetooth device by:

  1. Check if there is a built-in indicator or LED light that shows the battery status. Read your device’s manual to understand what each indicator means.
  2. Modern Bluetooth devices send battery-level data to the connected device. On your Galaxy S20, you can see this information in the Bluetooth settings, next to the name of the paired device.
  3. If your Bluetooth device has an Android app, it may display the battery level there.

Fix 03: Unpair and Pair the Device Again

A Bluetooth connection between two devices is established through a process called pairing. Once a device is paired with your Galaxy S20 the data related to pairing is stored on its internal storage.

If those data become corrupted, it leads to unstable connections. This is why unpairing and pairing the device again can prevent the Bluetooth device from getting disconnected from your phone.

To perform this fix, follow the steps below:

  1. Open the “Settings” app.
  2. Tap on “Connections”.
  3. Select “Bluetooth”.

  1. Tap on the gear icon next to the connected Bluetooth device.

  1. Tap on “Unpair”.

This will remove the Bluetooth device from your Galaxy S20’s list of paired devices and the data will also get removed from your phone’s internal storage. After unpairing, wait for a few seconds before pairing the device again.

Fix 04: Clear Bluetooth App Data

The Bluetooth service/app on your Samsung Galaxy S20 is responsible for managing all Bluetooth connections and storing their information on the device’s storage. If the Bluetooth app data has been corrupted, it will lead Bluetooth devices to disconnect frequently. 

To rule out this possible cause, you can clear the Bluetooth app data. This will remove all paired devices and any custom settings related to Bluetooth.

Follow the steps below to clear the Bluetooth app data:

  1. Go to Settings.
  2. Scroll down and tap on “Apps”.
  3. In the list of apps, find and tap on “Bluetooth”.

  1. Tap on “Storage”.
  2. Tap on “Clear data”.

After completing these steps, restart your Samsung Galaxy S20 and pair your Bluetooth device again.

Fix 05: Test the Bluetooth Device with Another Smartphone

If only one Bluetooth device keeps disconnecting from your Samsung Galaxy S20, there is a possibility that it is caused by the Bluetooth device itself. 

Bluetooth devices use a technology called frequency hopping spread spectrum (FHSS) to communicate with your smartphone. However, if the Bluetooth device is faulty, it will not be able to maintain a stable connection due to issues with its internal hardware or software.

A few possible issues in a Bluetooth device that cause it to disconnect from smartphones are:

  • The device’s Bluetooth module is faulty.
  • The device’s Bluetooth version or its software is not compatible with your Galaxy S20’s Android version.
  • The device’s battery drains quickly, causing it to turn off unexpectedly.

To verify whether the issue is with the Bluetooth device, pair it with another smartphone and see whether it continues to disconnect. If the device disconnects from the other smartphone as well, the problem is with the Bluetooth device, not your Galaxy S20.

If the Bluetooth device works correctly and doesn’t disconnect from the other smartphone continuously, it indicates that the issue lies with your Galaxy S20. In this case, proceed to the next solution.

Fix 06: Do a Software Update

A software update usually comes with bug fixes and improvements that can resolve any problems with the device’s software, including the Bluetooth connections. Here we are not only referring to your Samsung Galaxy S20 but the Bluetooth device (such as car audio, smartwatch, etc.) too.

This means you need to update both your Samsung Galaxy S20 and the Bluetooth device’s system software.

To update your Samsung Galaxy S20, follow the steps below:

  1. Go to Settings.
  2. Scroll down and tap on “Battery and device care”.

  1. Select “Software update”.
Software update
  1. Tap on “Download and install”.
Download and install
  1. Your phone will now check for updates. If an update is available, go ahead and download and install it to your device.

Note: To update your Bluetooth device, you need to refer to its manual for the correct instructions.

After the update is complete, unpair the Bluetooth device from your Galaxy S20 and connect it to the Bluetooth device again.

Fix 07: Reset Network Settings

Resetting network settings on your Samsung Galaxy S20 will restore all network settings including WiFi, Mobile data, and Bluetooth settings to their default states. This process will resolve any system-wide software glitches that could be causing the Bluetooth disconnection issue.

To reset network settings on your Galaxy S20, follow the steps below:

  1. Go to Settings.
  2. Scroll down and tap on “General management”.
  3. Tap on “Reset”.
Reset option samsung
  1. Now, tap on “Reset network settings”.
Reset network settings
  1. If you are asked to enter your PIN, password, or pattern, do it and tap on the Reset button to confirm the reset.

Once the network settings have been reset pair your Bluetooth devices again. After doing so, check if the Bluetooth disconnection issue has been resolved.If Bluetooth devices still keep disconnecting from your Samsung Galaxy S20 after trying all these solutions, it could be a hardware issue with your smartphone. In such a case, you should contact Samsung support or take your phone to a Samsung service center.
