The back glass of my iPhone 14 cracked

I have a brand new iPhone 14. Pro we had for two months and back glass cracked. It must’ve been dropped but I’ve dropped it before and I’ve never cracked the glass. Will they replace the back glass or the phone?The back glass cracked. And I have an OtterBox case on it. Are usually use the spec case and I’ve never had a crack ever. And it has dropped but I’ve never have a crack like this before.
