Hello. This isn't a big deal, because I can't see them when I use the phone and can only see the lines at a certain angle. I thought it might be because it was in my purse without a case on it so maybe some grease got on it (I don't think they're pixel lines?) We were putting on a screen protector today, so we cleaned it off, and they still stayed. I should also mention, I don't have a case with the top part of the phone covered, so it's not caused by a case. It also doesn't seem to come off when you wash the screen. I've attached a picture because it was easier to see in a dark setting. I should also mention, it's not just my Moto G, my mom has the same phone and they're on hers too. I don't see these lines on any other of my devices... what is this and is it fixable? Again, it's not a bit deal because it's barely visible, just curious and wonder if anyone else has this problem. Thanks in advance.
