How to install home and back arrow buttons on screen again

[Grammydi]

I have somehow lost my back arrow and home button and need to find out how to reinstall them! If anyone can help, it would be greatly appreciated!

Factory reset the phone?
Are you using a different launcher?

Have you used some app to force immersive mode?

I found that I had to go into my Moto button and shut off the one touch from my thumb print doing the directions, turn off that to having it be the arrows.
Thanks
