I know this will sound weird but here is a question. Both my wife and me just got the XR. I got mine first and then a day later, she got hers. I got the red and she got the coral. Both phones have the SAME screen protector and SAME case. But my phone *feels* heavier. I have asked 2 other people to just hold both phones and they have said "why does the red one feel heavier". Is it possible that the color can have a difference on the overall weight? I am NOT complaining or returning this fine phone. Just curious. Thanks!
