Hi, I have just got my new Galaxy S4, everything is working fine except the Bluetooth. I am having trouble to use the Bluetooth on my 2011 Toyota Car corolla. I am able to connect to the Bluetooth, and play music but problem with starting to make a call. when I say "starting to make a call" means I can make a call, but the receiver can't hear me and I can't hear them neither. I was able to answer the call or hang up, everything is working fine except no voice come out from the speakers. The funny is it will work if I use Apps to make a call, such as Skype, viber. I believe that is because the app use Internet. I have checked other threads, Samsung Galaxy S3 had the same problem, looks like they have been fixed. Does anyone have the same issue?
