So my left big toe was puffed up and in pain like crazy. I did not know what was happening it it. I could not see anything so I poked around on it and it hurt in the one spot. I got out my handy LG G4 and zoomed in all the way and looked with it at the spot. There it was, a tiny bit of glass. I pulled that puppy out and the toe was better in about an hour. Goes to show that for a phone this thing does wonderful macro shots.
