Well, I was not anticipating this, but so far I am NOT LOVING my SGS  III. I am wondering if any of you fellow Verizonites would be willing to  help me test this out, as I have already asked my friend with the AT&T version if his does this, and it does not:
When connected to the aux in (very common on cars and stereos nowadays,  you know, so you can listen to music off your phones and iPods and MP3  players, etc.) I now have the SAME incredibly aggravating problem I  could never resolve with my Fascinate. As usual, I have my bluetooth  connected to take the call. When I answer the call, I hear NOTHING over  my bluetooth unless I disconnect the audio cable out of the headphone jack!!!  This  is a huge safety hazard, as it takes your hands and eyes off the road,  requiring you to disconnect a cable every time you get a call!!
I called Verizon and complained about this with my Fascinate to no  avail. I never had this issue with my Droid X, HTC Eris, or my Galaxy  Nexus, another dual core Snapdragon based Verizon LTE phone made by  Samsung. 
Not to mention the SGS III is laggier and less responsive than my Nexus,  although not as bad once you disable S Voice (S is for stupid, by the  way, at least in my opinion ... I can't get it to work worth a darn!! Could be that I'm the stupid one, but I've  certainly given it a lot of effort in a very quiet environment.)
This is horrible because the screen is incredible, and the battery life  far outpaces every other smartphone I've ever had by a ridiculous  margin, so PLEASE, fellow Verizon SGSIII friends, help me out if you  can!! I don't want to have to return this phone, but reasons to do so  are stacking up.
If there's no fix for the audio cable thing, that is a definite deal  breaker, and enough to make the phone "defective" in my opinion. That is  such a blatant safety hazard. I do NOT want a "Fascinate 2". The other issues pale in comparison to the audio cable issue.
