Firestick Fast Task Killer: How Does It Work?

If you want to get the best streaming experience from your Firestick, you need to ensure that your device runs at the best possible speed with the least amount of lag and buffering.

However, most of the Firestick and Fire TV versions available today come with a limited amount of RAM which means that after you have installed several apps, you may start experiencing slowdowns and buffering.

This is because most of the apps continue running in the background even after you have closed them. Your best option in such cases is to use the Firestick Fast Task Killer to terminate all apps that are running in the background and free up more memory space in your device.

The Firestick Fast Task Killer helps you to instantly free up space in your device’s memory in an easy and fast process. It quickly scans all the apps that you had previously opened and are still running. Then closes them with a single click on your remote. It helps you save a lot of internal memory space to boost the speed and performance of your device.

In this post, I’ll show you how you can get and use the Firestick Fast Task Killer application on your device.

How to Check If an Application is Running in the Background

As stated, the Firestick Fast Task Killer works on all Firestick and Fire TV devices. You can always test to see how the application works by opening one of the apps you have installed on your device, for example, Netflix.

When any application starts from fresh, it usually prompts you by asking which profile you want to use. You can choose your profile and the app will open up.

When you press the home key and go back to the home screen then try to open the app again, you’ll notice that it doesn’t ask you which profile to use like it did the first time you opened it. This is because the application is still running in the background. That’s basically how you can test to see if an application is running in the background.

Most of the apps installed on your Firestick will normally give you a similar prompt when you open them for the first time. But once they start running in the background, they’ll open automatically without asking you which profile to use.

You can choose this hard way to check each app and see if it’s running in the background or simply use the Firestick Fast Task Killer to close all background apps in one click.

Why Do You Need to Stop Background Applications?

The more free memory your device has the better it will perform. You will also experience less buffering and lagging while streaming online content, especially if you have a fast Internet connection. It’s important to close all unnecessary apps running in the background to free up the memory that they would otherwise be using.

With more free memory in your device, you’ll see better performance and less buffering because the device needs a good amount of free RAM to cache the video stream and provide a smooth, uninterrupted, and consistent stream of the online content you’re watching.

The Firestick Fast Task Killer helps you to terminate all apps running in the background in one click. It’s quite easy to use too.

Unlike other apps that do a similar job, the Firestick Fast task Killer does not need to open each individual app with a prompt asking you whether to stop the app or not. It simply gives you a list of background apps and closes all of them at once. It’s fast and easy to use.

One of the major causes of lagging and buffering is low memory which is often caused by having a lot of apps running at the same time and hogging up much of your device’s RAM.

To free up more space in your device you need to constantly close all apps running in the background that you’re not using or hardly ever use. This is what the Firestick Fast Task Killer does for you.

With just a single click it will shut down all the apps you had previously opened to free up more valuable memory and make your device run better and faster.
