Light rustling noise inside the Tracker box

Hello.
If you move the Tracker slightly in hands, you can hear a slight noise inside.
Is this due to the clicking mechanism of the button or some kind of malfunction?

Thanks.

Are we talking about the OG Tracker or the Mini here?

If everything works as intended i wouldn’t be too concerned honestly.

Yeah, everything else seems to be working well.
It is OG Tracker.

I think that’s something to do with the key switches, mine has always done that

It’s probably about the keys )
Thanks for the replies!
