Question Strong rattling sound when shaking the phone

[Kluxe Nobody]

So by complete accident I noticed that whenever I shake my 11 Ultra, a strong rattling sound comes from the top portion of the phone, like there's something loose inside. After a bit of testing I assumed it's the OIS from the wide angle, since whenever that camera is used, and the OIS kicks in, the sound when shaken becomes very small. But anyways, is this normal?

This may sound like a strange request, but please, could you people shake your device and give a feedback here to know if it's just my unit?

Ah ah by accident too, i noticed the same few days ago.
And when i change camera lens in pro mode, i have a little sound similary as haptic.

That's reassuring, i am not the only one. But why we have this thing ?

It's the camera and OIS. It's normal.

It’s the stabilization module inside the camera shaking. It’s a moving part so it’s basically floating when you’re not using it. When you shake the phone you make it move inside the camera, thus the rattling noise.

And obviously, it’s for stabilizing the camera when you’re moving so you don’t get the blur effect.
