What is "Smart Standby"? My phone, a Blu Studio C 5+5 running Lollipop, has a toggle icon in the quick settings pulldown area labeled Smart Standby. I've found nothing in the phone's documentation or on Google that indicates what it does. Can somebody explain it?

Note: I've discovered that when Smart Standby is enabled, Tasker profiles which are tied to my calendar activate up to ten minutes late.
After some digging, I found a German site https://durcheinandr.de/technik/smart-standby-welch-eine-option 

To save you the hassle of translating, it states that enabling smart standby allows the device to automatically lock and turn the screen off when the phone is placed in your pocket, or on a flat surface.

I barely remember my German. God, that was hard.
