Closing Apps

Hey guys, my apologies if this has been answered somewhere else. I did some searching and couldn't find anything.

So I'm having a problem with my phone closing out of apps. Note 4 on 5.1.1. This can be anything, Facebook, games, etc. Basically the app loads, I press the home button, go back into said app, and it has to load again. It even does this when no other apps are open. Many thanks!

Let's block ads! (Why?)
