I used my car's bluetooth with my Droid X, and the call quality was great. People on the other end said it sounded crystal clear, and better than me just talking on the phone itself. I picked up a Razr, and now I'm cutting out and hard to understand on the other end. Is anyone else having this issue? I haven't been able to try a bluetooth headset yet, but I'm thinking I may need to take it back to the store and swap it for another one. I've messed with every setting I can think of and haven't been able to fix it. Also, this phone doesn't seem to automatically connect as well as the X did.
