I recently got a new Galaxy S8, but ive already noticed scratches on it. They arent too noticable ubless the screen is a certain color or if there is light on the phone but they really bother me. Please help!
There is no way to remove the scratches without damaging the screen coating. You may want to get a screen protector, that will cover the scratches and prevent more.
Try using a micro-fiber cloth (the one used to clean spectacles) that should remove whatever can be removed (marks that look like scratches but aren't; they won't come off with a finger or normal cloth though)
