Indeed it's a very useful feature... Because sometimes small shakes can occur when we try to press the shutter button in selfies. So this feature is helpful to take stable selfies. 😍
As another tip, You can use voice commands as well. By saying "Cheese" "Capture" or "Shoot". But First, make sure to turn on the Voice Commands option. (Open camera > settings >shooting methods > turn on Voice Commands). And if your device has a Bluetooth enabled S-Pen, It can also use as a shutter button 😊
