Is the matte black of iPhone7 easy to scratch or fade?

I don't think it will fall off, at least not yet. Scrubbing cream scratches easily.

Prevention:

The mobile phone cleaner is clean, and the ultra-thin soft fiber back film is attached after alignment, and the film is covered on the back shell of the mobile phone to completely isolate the humid air and hand sweat. Cover the screen with toughened film, and then put on the electroplated mobile phone case. All-round package mobile phone. It can effectively reduce the oxidation and paint peeling of mobile phones.
