If you've got some apps on your Galaxy S5 that simply refuse to close or that freeze so you can't get out of them, here are a few ways to force close an app, but we'll also show you how to disable an app or generally force quit or force stop one. Besides getting you out of trouble in a jam, closing apps is also a neat way to free up more RAM for faster multitasking.
Swipe away to clear cache
If you've just been using an app that you're not going to use again in the near future, you can simply swipe the app away in the Recent Apps list to clear it from memory. This deletes the app from the cache, meaning you now have a little more RAM to spare.
It also means that the next time you launch the app it will have to start from scratch, so it's not always faster. But it is an effective way to close an app completely.

Force close an app in Settings
If an app is being non-responsive or you notice that it sticks around long after it should have gone to bed you can force close it through your Settings.
I get this with music players like Poweramp and other apps that keep data syncing in the background even when you don't want them to. YouTube also does this. The easiest thing to do is force close the app by going to Settings > Application Manager and swipe to the Running tab.
Here you will easily be able to detect any apps that shouldn't be running (like a game you stopped playing yesterday (and hit the Stop button). Just make sure you don't shut down system apps you need running in the background, like Bluetooth, or any third party apps like SwiftKey or Facebook Messenger that need to be running all the time.
Disable an app entirely
If you have an app that is constantly running that you don't even use (but can't simply uninstall because it was pre-loaded), then you can just disable it. Head to Settings > Application Manager and under the All tab find the app in question.
I'm going to disable ChatOn as I don't really use it. Tap ChatOn in the list and you'll see some options for force closing, uninstalling updates or disabling. That last one is what we want.
When you tell your Galaxy S5 to disable a system app it will warn you of the risks, which include the loss of your data. While you can re-enable the app at a later date, disabling it will delete your current data.
If you're OK with this, tap Disable, agree that you want to proceed and, if necessary, agree to uninstall any updates the app may have received since you first got your phone.
Now, when you go to Application Manager you'll see an additional tab on the far right: Disabled. Here you can see the apps you've disabled as well as enable them again if you need to.
