I thought I had a perfect phone, until I heard the hissing. There should be a RECALL immediately! I wouldn't care if it was just a subtle sound you could only hear if you put ur ear to the back. However, this sound gets recorded into any video taken and is LOUD and obnoxious. It sounds like metal crickets/static in the top portion of the back of my phone.. probably an issue with the Intel chip or the new speaker placement.. It literally kills the video taking ability because the sound is riddled with nasty garbage noise... This is a design flaw and Apple screwed up big time. On top of this other people have countless other issues like bad screens, etc. Fortunately I got lucky there.. My brother and every other person I know with a iPhone 7 or 7 Plus have this hissing/static noise issue, along with countless message board posts saying the same thing. I'm returning my phone and waiting for Apple to address this, or I'm going back to the Note 7 as they've fixed the battery issue. They've released a broken product this year. There is no fanboyism here, just realism...
