A few things really struck me while making my way through this teardown of the iPhone 7 Plus.
The iPhone cover/display flips to the side, like opening a book. Good to know this if you ever plan to open yours.
The edge of the iPhone cover is rimmed with a caulk-like adhesive, which acts like a gasket to keep liquids out, aid waterproofing (water-resistancing?)
The iPhone is filled with lots of tri-point screws, similar to the ones used inside the Apple Watch.
Finally, I found this to be an incredibly good looking design, at least to my untrained eye. Good stuff.
But no teardown of the adapter. So there are still wild speculations whether there is a DAC inside or not. This is ridiculous.
