My wife bought the S4 and we called AT&T, Samsung etc... and they kept passing the buck back to each other and she finally returned it, much to the dismay of the AT&T rep. Her IT guy at her job did some research about an APP that might fix it, or an update from AT&T that fixes it for some.
Any ideas will be helpful, and we may go back and get the phone if we feel safe with a FIX for it??
Her issue is not pairing, it would pair, but she couldn't use her speed dial on her 2014 Jetta touchscreen, and sending and recieving calls worked sometimes, and not sometimes.
