Bluetooth device won't stay connected to Galaxy phone or tablet

Make sure your main device and the Bluetooth device both have sufficient power. If needed, plug them into an adequate power source or charge their battery and then try connecting them again.

Make sure Bluetooth is enabled on your phone or tablet. To check if it's turned on, swipe down from the top of the screen to open the Quick settings panel. Tap the Bluetooth icon to turn it on. The icon will glow blue when it's enabled and will be grayed out when it's disabled.

In order to connect, most Bluetooth devices need to be within 30 feet of the phone or tablet. Make sure the devices are close enough; otherwise, they will not connect.

If possible, restart the Bluetooth device. Then, restart your phone or tablet. This can help fix minor issues and may help the Bluetooth device connect again.

• On devices with a regular Power key, press and hold the Power key until the Power menu is displayed. Tap the Power icon at the top of the screen, and then tap Restart. Tap Restart again.
• On devices without a dedicated Power key, swipe down from the top of the screen to open the Quick settings panel. Tap the Power icon at the top of the screen, and then tap Restart. Tap Restart again. Alternatively, you can press the Side and Volume down buttons together to bring up the power menu until the phone or tablet shuts down.

Check to see if your phone or tablet has any available software updates and update it as needed.

Also make sure to check if your Bluetooth device needs any software or firmware updates. These are often overlooked. You may need to contact the manufacturer for instructions if you have a third-party device.

Some Bluetooth devices may need a support app in order to connect to a phone or tablet. For example, Samsung earbuds and smart watches connect through the Galaxy Wearable app.

If you are using a third-party Bluetooth device, please check with the manufacturer to see if a support app is required.

Disconnect the Bluetooth device and then pair them again to your phone or tablet. Sometimes this simple trick will fix connection issues.

You can clear the Bluetooth's data cache on the phone or tablet to completely reset Bluetooth. 

1. To do this, open Settings, and then swipe to and tap Apps.
2. Tap the Sort icon (the down arrow with three vertical bars), then tap Show system apps.
3. Tap OK and all the system apps will appear in the list.
4. Tap Bluetooth, tap Storage, and then tap Clear data. Tap OK to confirm.

You may need to reconnect the Bluetooth device in question, along with any other devices you had connected.

Test the Bluetooth device in different scenarios to help narrow down the problem.

• Try connecting other Bluetooth devices to the Galaxy phone or tablet. If other devices connect, there may be an issue with the Bluetooth device itself.
• Try connecting the Bluetooth devices to other devices, such as a computer. If they connect to the other device but not the Galaxy phone or tablet, there may be an issue with the Galaxy device.

First, factory reset your Bluetooth device if possible, and then test it to see if it's working as expected. 

From Settings, search for and select Factory data reset. Next, tap Factory data reset again, and then review the information. When you're ready, swipe to and tap Reset. If you have a security lock set on the phone, you will be asked to enter the credentials. You may also need to enter your Samsung or Google account information. To delete all information and downloaded apps, tap Delete all.

Your phone will reset; when it turns back on, it will start from the initial setup screen. Once everything is set up, try reconnecting your Bluetooth device again.

If the third-party Bluetooth device will still not connect, please refer the manufacturer's support for further troubleshooting.

If you believe the problem is with the Galaxy phone or tablet, please visit a Samsung walk-in service center. You can also schedule a repair service online.
