Ooops! I crashed my gopro Hero 4 black once back when it was new. I slammed my DJI Phantom 2 into the side of my gallery. It still worked by scratched the lens. Thankfully I bought insurance on it and gopro or someone replaced the lens. I also most crashed it again, it fell off my truck filming in the Rocky Mountain National Park. Thankfully it was tethered, so I didn't loose it. But It wasn't in its case either...I was using a gimbal. So it could have easily hit the lens again but it didn't. Here is a link to that video
