Android Central Question
I have just purchased an S9 (T-Mobile) and while it paired nicely to my car's Alpine system it will not store the passcode of 0000, making me type it in every time I start the car. Once connected it performs beautifully. My S4 had this problem until I let it store the phone settings but I don't seem to have this option with the S9. My old Blackberry performed this operation flawlessly but I realize that is comparing apples to oranges.
