Simple answer: It's useless with new phones. I have a Samsung Ultra S21 and I cannot maintain a Bluetooth connection for this device. I had to connect 4 times within 2 minutes. Loses connection within 2 feet of device, rendering Bluetooth unusable. You can't connect to Bluetooth the normal way, you have to use an app, Bluetooth will even tell you if you're trying to connect using the built-in Bluetooth service. in cellphone. Definitely not acceptable. If you install an app from Google Play, it will be rated 1.4 stars. The main reason is communication problems.
