    The S21 Ultra isn't working with Android Auto. Google's Android Auto Team is working the issue, but Samsung's support is non-existent. Best Buy just tells me to return the phone, they don't know what Android Auto is. The phone itself is good, 3-4, but wouldn't recommend it if you're going to use it on your stereo.

    Those phone is great, I loved it. A Geek squad female employee was extremely rude, as much as I spend with Best Buy, I don’t feel I, nor anyone should be treated that way. I made them refund everything simply because of one employee.
