This is almost a deal breaker for me... I have one day before I can return it, so I'dl like to know if anyone has issues with this, and whether it's a concern for you. When I have the HotSpot on and I"m talking with a bluetooth headset, the bluetooth call quality is bad. As soon as I turn off the HotSpot, the bluetooth quality is good. My goal was to be able to use my laptop with the HotSpot while talking to clients via the bluetooth headset. As a backup, I can use a wired headset/mic, but I hate the cord, and now I have to have the phone close by, rather than by the charger (which we always need.) I was told by one VZW tech agent, that this is as good as it gets. This is my first smartphone so maybe my expectations are too high. I guess I could go back to not having this, and saving $60/month. Thanks for any feedback.
