Should the flashlight switch off automatically in Android 5.1?

[AC Question]

Hi,

Question as in topic.

Essentially, I've apparently left it on while in my bag for, say, half an hour which cause the battery to become really warm (obviously). But I would expect it to switch off itself after a while.

Does it have such a feature? If so, how do I access the timeout value? Or where do I check if this feature is enabled?

Thanks!
