Hi I am playing visual novel games and am on mobile android a Samsung galaxy s7 and when I get to a portion of any game where i name my character or have to type in general the keyboard pops up but then when I'm done typing and try to go off the keyboard it just keeping a piping back up no matter what I do.

it's an error in the game but also an error on Samsung which both crate the mess you experience. I also have a samsung and i know what you mean, the keyboard will only go away when you press the back button. Some developers will do a better job and program the keyboard to close when you press "done" button in the keyboard.
