Dust in Front Camera S22+

so i bought an s22+ from UAE in around september. Since then there seems to have been a pretty thick layer of dust settled on my front camera, like beneath the screen on the lenses. I showed it to a local repair shop near my area and he said that the dust is going from the earpiece slit and clogging the front camera, he cleaned the camera in front of me. But since then i can see dust settling again. So basically my question is have you guys encountered this issue? Is there something i can do to fix this what are my options. The phone otherwise works flawlessly. Any help would be appreciated thanks!
