Rattling sound in my iphone?

I was once texting my friend and i was tapping on the top of my iphone and i heard a rattle noise, so i started tapping on the back too near the camera and it was still rattling, and also on the bottom of my iphone on the back it was rattling, this is driving me crazy i just bought my iphone, is it broken? What is it there? Its not just near the camera please help

Added (1). The rattling noise is everywhere on the back of my iphone! I'm not convinced its broken since i just got it please help

It sounds lije sinething has come out of the back of the phone and the casing is trapping it inside - could be a screw.

Id advise you ti take it to a local mobike repair place who can take the casing off just so iff anything has come loose or gotten trapped in the casing it can come out

I have been wondering the same thing about my iPhone SE for a few weeks now. I was going to take it in, but there are so many other people with the same sound and in many different iPhones. This makes me feel like this could be a part that is meant to be loose. A lot of people suggest this is normal in the camera function and it would be hard to believe that the factories are making THAT many defects in THAT many different phone styles.

The distinctive sound also has too much "play" to be just a loose screw. At least on my phone. I'm worried about the sound a little because this was an expensive purchase, but my iPhone works perfectly fine as well as the camera. A little camera like that has got to be complicated and with unique parts. Until my phone isn't functioning correctly I'm going to ignore the sound.

Also gotta remember that the phones screen is able to change its orientation. This could require a free part that is able to move.
