Why are there smudges on my photographs? Uncategorized September 11, 2021 Forums AndroidCentralLeave a Comment on Why are there smudges on my photographs? Got battery replaced on my S10. When I got it back from the shop, I noticed the rear camera pictures have 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? Sharing is caring!
