Hi, I searched the iOS 10 forum and didn't see this topic come up, so sorry if it's already there.
I upgraded my iPhone 6S to iOS10, wife too. Now, when we "swipe" up to get the flashlight icon, mine is totally not there anymore! It's like they removed the flashlight from my iPhone. On my wife's phone, it is there, but greyed out! Seems like a major bug, especially for both our phones. They literally removed a major feature, for me, as I use the flashlight icon at least every day.
