I have just bought a new phone Samsung A51 and its bluetooth is not working properly. I had connected it with my new boat earphones. And it disconnect so many times. Same problem happened with my Ford Figo cars Bluetooth It automatically disconnect. So many time so kindly provide me the solution.
Give this a try, on your phone go to your settings and in the finder search bar type in "reset network settings" and select it. Resetting the network settings will also reset Bluetooth settings. Once you try this, go ahead and reconnect your device and let me know how it worked for you.
