Back in August the entire glass element AND the bezel wouldn't stay on the phone, so I had to replace the entire back housing just for the lens.
Then a couple months after that, I dropped it from about 3 feet while sitting on a chair and cracked the lens. Been like that since, but it doesn't affect the photos as far as I can tell. Unless the sunlight is hitting it at just the right angle.
Also replaced the speaker 3 times, until I found out I can just use a magnet to pull metal shavings off of it
And yet, I've never broken the glass. It's been dropped off the top of my truck (long way down), dropped in a pool w/100% submersion, and fell out of my pocket while on an ATV and run over. Soft ground saved it there as it was able to sink in. Never had a case either.
