do 6/6s cases fit iphone 7

Yes, but....... The camera on the back of the phone requires a different opening than the iPhone 6 or 6s, so it really won't work. I put one on when I first got my phone to protect it on the way home, but needed to purchase a new one asap. The iPhone 7 requires a larger opening, and the iPhone 7 Plus requires an even larger one, since the camera has two lenses. The rest of the dimensions are the same.

You're welcome.
