Restart the device

First thing first! There could be some anomalies in the system altering the connection between your Bluetooth device and the phone. Software related issues like this are solved by restarting your phone.

Just click and hold the power button, then tap 'Restart'. Otherwise, you could also restart your phone by long-pressing the power button for about 8-10 seconds.

Turn off and turn on the Bluetooth connection again

Swipe down the quick-setting panel

You'll see the Bluetooth icon, tap on it to switch it off.

Now tap on it again to turn it on.

As well as restarting your Bluetooth connection, kindly restart the Bluetooth device as well.

Clear the Bluetooth cache and data.

If the Bluetooth is not connecting android properly, you might have to clear the stored app data and cache for the Bluetooth app. Just like every other app on your phone, Bluetooth also stores some data temporarily. To clear this, kindly head over to settings.

Depending on your Android version, kindly tap an option to display all apps.

Now scroll through the apps until you locate 'Bluetooth', then tap it.

Tap on 'Storage & cache'. You can now clear both the storage and cache data from the menu.

After that, reconnect with your Bluetooth device to see if it works.
