dirt

dear friends, my device came and i noticed some stain spots on display after i remove the protective paper on display. They were located on same area and other regions of display were completely clean. I have cleaned this area with cloth and all gone. Has any one experienced sth like this?

I don’t know how I got this scratch. It’s very tiny and faint but I always used a clean silicone case. What do you guys think. I’m thinking that it already was there out of the box and it came from the factory itself. The scratch is above the flashlight (not on the camera area).

This is Linmon table top & magic mouse. The gunk makes the mouse movement slower. Do I need a mouse pad for my office table ?

Does anybody know what the heck this is or how to get rid of it? I've had it on my display for over a year and I can't put up with it anymore. Whatever it is it's underneath the glass. It might be hard to see in the photo but its almost like a charred area in the corner with a couple streaks...

Hey Guys, I don't know if it is appropriate to post in here, if it is not please remove it, thank you. I bought an iPhone 7+ few months ago, and few days later I noticed there is a dirt inside the lens, but I was so busy because it was my last semester and due to my past experiences with Apple...
