There’s a bit of a protrusion on the back of the iPhone 6 and the iPhone 6 Plus. It’s the back-facing camera’s rim and lens cover glass. There’s only one way to fix this piece of the iPhone 6 and iPhone 6 Plus. One way to make the back of your iPhone flat. And it’s going to destroy your camera.
Before you view the following video, know this: it’ll destroy your ability to take photos. There’s no good way to do away with the non-flatness of your iPhone 6 or iPhone 6 Plus without adding a case to the device.
You should add a case to your iPhone 6 Plus anyway, so you may as well do that no matter what.
The solution the folks at Peripathetic Pandas opted for was a bit more rudimentary. They decided to grind.
Grinding will result in the lens being destroyed, and likely the rest of the camera setup being destroyed as well. In effect this whole situation is a joke. Don’t do it.
