Hi all, I have my s25 ultra since January and have not used a camera protection on it, as I read it actually worsen the quality. Also I have seen reviews saying the camera glass is scratch resistant etc. But yesterday I randomly noticed a faded line on my main camera (middle one). It is not a scratch per say, but it is something nevertheless.

For context, I assume it happened due to sand, as I have been playing in a sandbox over the weekend, while also taking some pics here and there.

What is your opinion? Should I put on camera protection while its still not a proper scratch? Thanks in advance!
