iPhone 6 video recording hissing upon playback

[weksa]

Hi, new to the forums. I got a new iPhone 6 and it's updated to iOS 8.0.2. I only just started recording videos after the update, so I can't speak to what it was like before.

When I playback my video recordings (rear camera), there is an undulating hissing. I never got this on my iPhone 4, which was my last phone.

I've tried restarting the iPhone, but it made no difference. Is there any other troubleshooting, or do I have a bad video recording microphone?

I ordered the iPhone 6 through AT&T and it got shipped to me. Do I just take it into an AT&T corporate store for an exchange?

Wow. Yea now that I'm lessening to a video that didn't have much background noise I can hear the hissing. Hope it's a simple software fix

Ah, I hope so too.
