S22 ultra here, when I shake my phone there is something rattling, I always assumed it was some part of lenses, since they have some advanced stuff like periscopes and maybe for some good reason some part is not tightly held as the rest. Otherwise there shouldn't be a thing moving in the phone.

As long as it keeps working no concern, and it works fine, focus is quick. But yeah I won't be mounting it on motorcycle (or mountain bike) anytime soon

Most phone cameras rattle while the camera is off. If you turn the main camera on, then it normally stops the rattle temporarily, since the rattling lens assembly is now held in place electromagnetically.

True, tried turning it on and with 10x zoom it stops, just as expected periscope is the culprit. Learned something today, thank you

Any phone with OIS or AF will rattle if you shake it hard enough. It's just the springs of the lens assembly hitting the endstops of travel. Shouldn't damage anything unless you really hit it quite hard (or, repeatedly, as a motorcycle would). I've also noticed you can sometimes get rattling from buttons on a phone too. Could also be that.
