LG VX-8300

Well i have had this phone for 3 days and the problem that i am having now is that when i am on my motorola HS850 bluetooth headset and on the phone and someone else calls. I will click over from the headset and it will change calls fine but when i click back over it still changes back to the original caller but the name on the phone doesn't change and the front screen backlight doesn't turn off until i end the call. Is anyone else having this problem with their phones or can someone else test out this problem and get back to me on it.
