There are two white marks at the top and bottom of my (Verizon) Note 4, are these just cosmetic? Also, not as obvious, about 1.5" from the bottom on the power button side of the phone there are 2 more white marks - almost unnoticeable. And, between the marks, if you look closely, there appears to be a slightly raised area. Does anyone else see this on their phone and do you know what it's for? (These are all stock images since I'm at work and can't get a picture of my phone with my phone.
