Galaxy S8 and S8+ occasionally remind you to clean the camera lens for clear shots

Alright already, we get it! Clean lens equals clear shots. Not that hard of a concept to wrap your head around.
Considering how wide-spread of a problem this apparently is, and the location of the fingerprint scanner on the Galaxy S8 and S8+, it was a clever move on Samsung's part to implement an interface that automatically and occasionally reminds users to wipe off the camera lens.
The message appears in-camera and is displayed only after you enroll at least one fingerprint on the device and start using the scanner on the back as a means to authenticate yourself. It is almost as though Samsung knew that a lot of people would inadvertantly touch the camera when reaching for the fingerprint scanner!
