I had originally purchased a black 128GB iPhone 7 Plus for AT&T from the Apple Store yesterday and I had a few issues with it. Namely the sizzling (hissing) coil whine, a dimmer display than accustomed to with my 128GB iPhone 6 Plus, terrible feedback when recording videos, and a unibody that creaked or popped randomly when holding it immediately after not touching it for a bit. I know many here share the same concerns I have (had) so I wanted to let you all know about my experience today. Luckily, I found a 256GB iPhone 7 Plus in black at a nearby Apple Store. Much to my delight, zero of these issues are present in my new iPhone. The aforementioned issues must be minor defects in the manufacturing process. Do not settle with anything that is bothering you with your current 7 or 7 Plus. I am so happy now that I can sit back and enjoy my new phone as should everyone else who has purchased one. We are all paying top dollar for our iPhones and I can safely say that my new phone has not one of the issues that my original one had. Please post any similar stories or anything related.
