Hi, I'm a new user of the Macbook. My screen is full of smudges after I got a battery n top case replacement 2 weeks ago at an authorized service center. Is this normal? I try clean it with a microfiber cloth with some water on it but it's still there. And if you noticed, there's a micro scratch/swirl mark on it (I don't know if it's because of the scree replacement or if it's already there before)
