I installed a ballistic glass protector and found that it caused some glare when pointed into the sun so I removed it while waiting a coated glass protector to become available. Liquid glass (ceramic coating) should do the same and I personally wouldn't want a coating that bonds to the glass.

if you're using a case, just make sure you get a case that has raised edges around the camera module. Most Samsung cases are minimal around the camera, but there are a lot of 3rd party cases that offer more protection
