Sure hope the 6 records video in stereo !!!!!!!
It sure is a really nice feature when a phone (using 2 mics) records video in stereo.
My Galaxy S5 stereo audio output sounds amazing when recording videos for YouTube or just personal stuff that I edit on my iPad Air with iMovie,,, all my past iPhone's including the 5s kinda sucked in comparison audio wise with their mono audio recording.
Not a deal breaker if the 6 doesn't record in stereo (I'm still getting the 6 ASAP) but it will be a disappointment if it still just records in mono,,,,, yea, I know, they make stereo mic's that can be plugged into the iPhone, and own a few, but still a bit of a pain to have use an external mic when so many other phones like my current S5 automatically record in stereo,,, it sure make's a big difference.
Just ranting and waiting for the 6 to come out into the wild.
