Closing apps and tablet navigation

[cb2367]

I just got the Galaxy Tab A and am trying to figure out how to close apps. When I'm done using an app, I press the home button. I'm thinking though that this just closes the app, but it's actually still running in the background.

When I searched Google, the top result indicates to press and hold the home button and the task manager will open. This actually opens the Google assistant.

As for navigation, without a physical navigation button or an onscreen button, how do I navigate around on the tablet?

Settings, Display, Navigation bar, navigation buttons

Is there a reason you want to close the app out from RAM? This is not how Android was designed -- you should let the system manage RAM automatically. Just because an app is still in RAM doesn't mean it's actively using battery and CPU cycles. A properly coded app in the background should be paused/cached, and therefore not be actively using any resources (unless it's designed to, e.g. a music app that continues to play music in the background).

If you habitually close apps, you may actually cause more sluggish performance, since when you want to go back to that closed app, the system will have to load it back up into RAM, which takes a little more time and battery than if it were still cached in the background.
