There are 2 small gray spots visible in the camera image at 1X zoom (see 4th photo). The spots show up in the resulting photos. They are not there at 0.5X, 2X, or other zoom presets.  This is the only thing I'm aware of preventing this phone from being MINT 10/10. Screen is gorgeous and perfect. Phone has had a glass screen protector and been in an OTTERBOX case since new. Screen protector has a few light scratches, is slightly off-center, and some tiny air bubbles, but can be removed if desired. OTTERBOX case is in very good condition and has a few light scuffs and one rough corner (2nd to last photo).
