Chosen Solution
Got battery replaced on my S10. When I got it back from the shop, I noticed the rear camera view and pictures have a number of smudges. Took it back and they said they opened it up again, cleaned the lens, etc. but the smudges are still there! What could it be?
Maybe they only cleaned the lens on the back glass and not the cameras themselves. I would take it back and ask them nicely to try again.
