Hi, I just recently upgraded to the Galaxy S3(Verizon) from an HTC Evo 4g (Sprint). I love the phone, but I'm having a very annoying issue using my car's AUX 3.5mm(on both ends) headphone input to play music/podcasts. I know from years of using the Evo that there is no issue with my car's AUX input. Anyways, When I plug the 3.5mm input into my S3 and try to use the AUX input on my car, the music plays out of my phone's speaker instead. I have noticed that if I unplug the audio cable from both the car stereo and the phone and try plugging in each end, starting with the phone first, I can get it to work eventually (usually not the first time). However, this is less than ideal and a huge pain in the ass to have to do every time. With all other devices that I've used I am able to leave the end that's hooked up to the car stereo connected at all times and just plug the other end into the device I'm using without issue. But not with the S3... Even when I am able to finally get the sound to play through my car speakers I have issues. I've noticed that if I get any text message, call, or notification of any sort, the ring or notification sound will play through my cars speakers and then immediately after this, my music will start up again and play through the phone's speaker. This happens whether or not I actually do anything to acknowledge the notification. Not to mention, the sound for a notification is preceded by a really loud and random heartbeat noise going through the car speakers that I never hear when the phone is unplugged from the car. I know there's a heartbeat vibration setting, but I didn't think vibrations would play through the AUX input. It's very strange and it sounds like something just hit my car. Has anyone else had similar issues and, if so, have you found any solution? I know from using a number of other devices that this is not typical behavior. Is it possible this issue is just with my particular S3? Thanks a bunch in advance!
