I was at the Unpacked in person. And played with these phones on the show floor and in private setting, and I noticed the rattle at that time. It is completely safe and normal for these large camera modules to have some rattle. Some older phones actually rattled too, but since their camera hardware was much smaller, it was much harder to notice. The new Motorola Edge+, that just launched, has a very similar camera set up and it rattles just as much. Some YouTube reviews have mentioned it, but there were also several Forums discussions on this topic too.
Anyway. There is nothing to worry about, just try not to pay attention to it and not shake your phone as much : )
I did not even notice that to be honest. I have the Galaxy S20 ultra 5G. Mine rattle when I shake it. I think its the built in camera. The optical telescoping lense. Not sure if its supposed to be normal.
Really? .. even if you don't hear it in you pocket this rattle indicates parts shaking... thank for you comnent.. but really?
"That car makes a funny noise when I start it ... 'don't start it!'.. LOL
I have an s20 ultra. I have noticed this yesterday and called Samsung and they have asked me to return this and get a new one. After looking at this page I am no longer concerned now
