Multiple smudges on s6 camera

[Zak Asis]

Many specks and smudges have appeared on my phone's rear camera recently. The glass in front of the camera has been broken for a while, but it didn't affect the actual pictures taken at all. Only now did they show up. I'm afraid that these smudges are on the actual lens itself. Can anybody help?

I'll also add that I tried blowing it with compressed air, only to no effect
