Samsung gives app lock but kept it hide I don't know where but you can find it by activity launcher app. But when you open activity launcher, it gives you a pop up that use this at your own risk. Then whom gonna use that if that is so risky ?
According to me samsung should give that option of app lock in default settings because that is the only option which is missing in the galaxy device and that option is very important and very useful. Everyone needs that I don't know why samsung make it hide.
