How to check if I have the iPhone 5?

How do I check if I have the iPhone 5?

What you want to check?

Why do you need to check? Either you have one or you don't.

By comparing it with a 5s you could recognize easily.
Here are the differences:
1. The color of the back.
2. The Dual - flash camera which iPhone 5 doesn't have.
3. The fingerprint identity sensor which iPhone 5 doesn't contain.
Hope I helped.

The iPhone 5 is the only 4" iPhone without Touch ID. Of course the 5c doesn't either but that has a plastic back so that's easy to differ as well.
