back camera module rattling

[ZeneticX]

I'm wondering if anybody tried shaking their phone before and noticed that the back camera module rattles? Sometimes it happens and sometimes it doesn't. I'm figuring it's probably the OIS but I'm worried, is this normal?

My note 4 does the same, my Lumia 925, same. My m9 nothing. It's the OIS and the fact the lens is designed to have some movement, to counteract the phones movement.
