Ok bro. If you live in a dusty environment, or just want some layer of 'shield' you can use Gadgetshieldz Lens protection guards...it covers the entire camera border so no chance of dust entering.
And then you can use Samsung original protective cover...it's the best case I've ever used, comes with a kickstand also.
Order from southport.in....it's official Samsung Exclusive store....they have many stuff in stock always (which Samsung original website does not have 🤪) and have other original Samsung accessories as well.
The dust is not inside the camera lens per se. It's actually between the back cover and inner camera lens. So, it can be easily removed in the service center.
