What's wrong with the iPhone 7 and its colors?

Question

iOS

Situation I bought a used phone. I check everything. The model number starts with M
I pierce through the site it turns out everything is as it should, a black iPhone 7
I pierce in other places it is pink, I connect to amazing and itunes the same hat, athos is pink, what could it be?

Answer 1

Most likely, this phone was restored from several. The case is from the original black, which is why it is found on the site, and the motherboard is from pink, which is why it is displayed on the computer.
