So there's a good chance I'll be leaving my Note 4 for the LG V20. This will be my first potential phone where there's no front physical home screen button. I've owned all previous Notes and have grown accustomed to the feel and functions of that button. My question is whether the back finger-print button on LG devices function as the physical home button does on Samsung devices - return to home, long press to get Google Now, etc. -?
