Yep, I'm doing a gate because this is the second 7 Plus with the exact same issue (first was AT&T GSM model, and second is Sprint GSM + CDMA model - both unlocked). Different factory builds, too, and from different stores. The screen or body is clicking against something, and it's really easy to replicate. I have the clicking frequently (but not always) when pressing hard enough to enable 3D Touch on the lower areas of the screen (and no, this is not the haptic feedback). In a case, this is reduced somewhat, but it's still frustrating. As you can see, this is with just one finger. This is not huge amounts of pressure/holding it wrong. Here's a demo with the screen off. It's really annoying, and loud in person. Turn your volume up! This coupled with an even more yellow screen than my first unit, - I'm sitting out the iPhone 7 Plus year. (As a sidenote, both my 7 Plus devices suffer from Hissgate, too, which only manifests itself in video, but still... just... this hasn't been Apple's finest launch, that's for sure).
