In my excitement for getting the iPhone 5, and then restoring a few times and having to deal with little hiccups with the iPhone, I never took a video until Saturday 9/29/12. Well, when I took this video it filmed beautifully but there was no sounds. Instead there was a hissing noise. In trying to fix this issue, I did a hard reset thinking, oh, this can't be, maybe this will fix it, all the while hoping it wasn't a hardware issue. The hard reset didn't work. I did a full restore, that too didn't work. I called Apple and the Tech wanted me to do the very same things I had already done. I informed them that these things didn't help the issue. We did a final test using the Speaker Phone and they couldn't hear me so they made an appointment for me to go into the Apple store and get a swap out. I got a ride to the mall - I mention that because it is significant as I don't own s car and it's a big deal for me to get to the mall at such short notice. The Apple Genius did some tests and decided to replace the iPhone 5. The replacement phone worked, as best as I could hear in the extremely noisy mall Apple Store. There were so many babies and small fries in carriages on Saturday night! Really people?! My God! Amazing! Anyway, it seemed to work. I did a restore from iCloud when I was in there and did another test video after and it seemed to work. No hissing and I could hear my voice as well as see the video. When I restored in the store from iCloud, for some reason the restore was from Thursday not a more recent one. I was missing some info, so when I got home I did another restore from iTunes using the backup from Saturday morning assuming everything was fine, as this was a new iPhone and that Mic problem was a hardware issue. This morning I took another video. There was sound but it was accompanied with an annoying hissing noise. WTF?! I am wasting screen protectors on this. I’ve got to make another Genius Appointment and I am going to get an iPhone that records video with uncompromised sound! This is annoying. I take a fair amount of video and I need them right. My theory, I believe the headphone jack being on the bottom next to the Microphone is causing issues with the Mic. It shouldn't, but I think it does. It didn't when the Mic was on top next to the headphone jack, but now there's a problem. Anyone else have a similar issue?
