How do I stop my Galaxy S4 back button from glitching?!?

[AC Question]

I had my screen replaced and now not only do the back and menu buttons not work, but they also keep randomly doing their job overtime when I don't need it! I have the assistant menunpn so I can still use the phone, but the back button especially keeps having these little glitch out sessions and it sends me out of apps all the way to Google search for some reason. Help please!?!!!
