Mate, did you find any solution for this?

I don't believe there will be an answer. My customer has been having this problem since he got his XPS18 in June 2013. I feel bad about him buying this dell because I vouched for this company. He paid over $1500 for this thing and not only have the product not lived up to it's name, but the customer service is so basic and not helpful at all for this problem. I check periodically to see if there was a fix for this issue because it bothers him alot since his old HP with Window7 can be used as a handsfree device for his phone without any problems but he uses this machine now and it is not functioning.

My Toshiba P925U Tablet/Laptop had the same issue for several months after I purchased it in September 2013, but by January 2014(the next time I checked up on it) they had developed a fix for it. Now my Toshiba Bluetooth works fine with my phone and other devices. I have been hoping the same thing happened here, but I have given up hope because there has been NOTHING!!! I really can't continue to get help for this because his warranty is expired before we could get this rectified.
