Some phones didn't have a noticeable way to access flashlight. My workplace gave a Galaxy V which for the longest time I thought didn't have a flashlight. Apparently there was a torch widget and that was the only way to access it. It was the same on my Note 2.Beyond turning on the flash LED, what features are you looking for? Simply turning on the flash LED can be accomplished (in Marshmallow anyway) by utilizing the "flashlight" icon in the quick settings pull-down which is also accessible from the lock screen.
