What happens when you press airdrop and camera at the same time?

Apparently, if you press airdrop and camera buttons at the same time, your iPhone is going to crash completely, so it is not advisable to do this. Many people were curious to see what would happen if they did this (even though the phone itself said it shouldn't be done) and they saw that it messed up their phones. It is said that this problem was fixed after an update, but I'm not sure about that.
