Purple flare in my iPhone 5's camera. Is this normal?

I got my iPhone 2 days ago and las night I was trying to capture the light of my room and after I took the picture, I saw that there was a purple flare in the picture. It's not that dark but still, I'm worried. I only 1 week for its warranty so tell me iPhone 5 users, is this normal?

Yup. It's the sapphire crystal lens.
