Chiming in just because.
I work in a fabrication shop. Terrible place for a smartphone because of all the metal shavings, grinding dust, hot metal, spatter etc etc, plus its the ballistic nylon variant so it would easily melt if any hot sparks or spatter hit it. I had my phone for about a week and a half and I keep my phone in my back pocket. I went to pull my phone out and it slipped out of my hand mid-pull and flew about 10 feet, hit a metal table and bounced off the ground. I never had a chance to get a screen protector or a case so the phone was completely naked. Luckily nothing happened except a dent on the side of the phones bezel. I left it in my truck until I got it properly protected. Those metal shavings are a ***** though due to the magnets in the speaker collect all kinds of metal shavings.
