Why doesn't my Android keyboard pop up many times when I touch the screen for where you enter text

[Android Central Question]

My keyboard is starting to not pop up when I press on the screen where you need to enter text. Doesn't happen all the time but it's happening frequently and getting very annoying. I looked online and I can't find anything in my settings that are referred to to fix this like "application manager" or "keyboard" or the word "all" under apps.

tap:
Settings
General Management
Language and Input

At very bottom of the menu is a slider where you can adjust pointer speed.

Increase the slider to make the display more sensitive, decrease it to do the opposite.
