So... I'm returning my Nexus 5 for a replacement. I just discovered yesterday that my microphone has a serious problem with static noise. As in, regardless of what kind of room or environment I'm in, it sounds like a hurricane is tearing through my videos. (I don't record a lot of videos or stuff like that, which is why it took me a while to notice.)
Here's what it sounds like. It's apparently a somewhat common hardware defect.
Contacted Google Play Support and hopefully I have my replacement by the end of the week. For those who've had to replace their N5's for whatever reason: Did you get a brand new unit? Or is it a refurbed/recertified/respiffied one? just curious.
