First let me say that this thread seems to be about two (2) different problems under the same heading of "Problems with Samsung S3/Jellybean/Bluetooth." One problem is dropped bluetooth connection(s) and the other problem is static/noise/garbled sound on stable, connected, OEM in-car bluetooth audio systems. My problem is in the latter category. I have a 2009 Bentley GTC; everything worked fine with my HTC Droid. Bought a new Samsung S3 and it too worked fine -- for two days! Then static/noise/garbled sound (people on other end of calls either got noise or nothing at all); I assume the S3 updated and that's when the trouble began. I went through all the steps with Tmo and Samsung and tried three different S3's from the Tmo store but they all did the same thing, every other brand of phone that was paired with the car worked fine. I finally had the Tmo store give me a Google Nexus 4 which I don't like as well as the S3, but it pairs up in my car and there are no bluetooth problems at all. So clearly the problem (the static/noise one anyway) is squarely in Samsung's lap. Samsung should be able to figure out what they've altered or over-layed in the basic Android OS that is causing the problem and fix it.
