Do we really need permissions in android 6? : After all the hassle of searching on google, I have managed to request storage permission, to make my apps "compliant" with the new permission system introduced in android [Marshmallow][1]. But now, I noticed, I actually didn't need to make all that effort as permissions get granted by the system automatically without requesting. (seen while installing ES File Explorer, or my own apps). Do we actually need to request permissions?

PS: I am using a Samsung Galaxy S7
