I'm currently using Moto e5. It works fine but sometimes the navigation bar stops working. After I off the screen and again turn it on it starts working again.
Welcome to Android Central! When the nav bar stops working, does the whole screen also not respond to touch? Or is it just the nav bar? How often does it happen? Does this persist after a reboot? If it happens pretty frequently, see if it goes away in Safe Mode: https://support.t-mobile.com/docs/DOC-38073
