Best No-Root Firewall App for Android

In the Android operating system, you can switch between Wi-Fi and mobile data easily without any problem. And also, you can turn off the connectivity to the internet totally when required. The problem is, Android doesn’t give you any feature to manage or change what applications can and can’t access the internet facility or how applications access it. However, It doesn’t mean that you can’t handle how your android device is accessing the internet.

However, you may have seen that android offers you an option like “Restrict app background data.” Firstly Let’s talk about it.

Can We Disable Internet access for some apps in Android without any app?

The most straightforward answer for this question is you can’t. But you can block apps from accessing the internet facility in the background. To do that operating system of your android device should be Android N or higher. If that requirement is met, tap on Settings > Apps and select the application that you want to block background internet access. Then, tap on “Data usage” and click on allow “Restrict app background data.” Now, all the apps installed on your android device will not be able to use the Internet facility while running in the background.

However, even after doing the whole process, if you open any app installed on your android device, it will use the internet facility without any restrictions. And this is the point where Firewall applications come into the scene. So, let’s see about that.

What is the Best No-Root Firewall App For Android?

There are many firewall apps in the play store. Some of them need root access to work properly, and some of them are full of bugs and errors. I found a 100% working simple application called “Netguard.”From here, let’s see some information about that fantastic app.

How to install?

You can install this firewall app in two different ways to your android device. The first one is by going to the Play Store, typing as Netguard, and tapping on the search button. Now you may see many such applications like this. But you should click this particular application with the name Netguard. The second way is much easier than this. Just tap on the Get it on Google play button below. It will redirect you directly to the Netguard application page on the play store.

How it works?

After completing the installation process open the application by just tapping on the open button. When you open this app, it will ask for permissions only for the first time. Make sure to select it as I agree now. Then it may ask permission for a VPN connection request. Put the tick mark on Don’t ask again and click on the OK button.

Netguard app permissions

Alright, this is the time to check whether it’s working or not. Now you can see a switch on the upper corner of the left side. Remember to keep constantly on that switch. Otherwise, the Netguard app will stop working until you are on that switch.

So here, you will see a list of applications installed on your android device. And also, you can see that in front of those applications, there are two symbols. One symbol is the Wi-Fi symbol, and the other one is the mobile data symbol. You can block the internet access of any application from both ways as you want.

When you’re connected to Wi-Fi, and If any Wi-Fi symbol is off in any particular application, it can’t be run during the Wi-Fi. Still, when only the Wi-Fi symbol is off, it can access the internet through mobile data if you access the internet.

So now you can switch on and off data for the particular application or application in both ways separately. You can see the number of applications that can access the internet and are blocked by it.

Netguard app options

Now let’s see how to on/off dark mode of this application. Click on three dots that show the upper corner of the right side. Then click on the settings and then click on Options. Now you can see the use dark theme option you can switch on or off as you want.


This application has many more options like this. I recommend you to go and check them out by yourself. That’s all for now. See you guys in the next post.
