So in the past few days, I’ve been showing you a bunch of new features that you’re about to enjoy on Android Nougat OS. I’ve already shared about the Night Mode, the quick app switching, the dual split-screen mode and some other features related to Android Nougat OS.

I’ve also already given you the tutorial about how to restrict internet access on some specific apps by using the Data Saver on Android Nougat OS.

Unfortunately, just like any other features aforementioned above, this Data Saver is only available on Android Nougat OS, which means you cannot use it until your device gets upgraded to Android Nougat OS.

The good news is, there’s a workaround for this feature if your device won't receive Android Nougat update. However, this trick requires root access of your device, which means you won't be able to enjoy this feature if your device hasn't been rooted yet.

Okay then, without further ado, below I’m going to show you how to restrict some specific apps from using the internet connection on your device.

How to Use Droid Wall?

1. Your device must be rooted first. So yeah, as I mentioned already above, if you want to enjoy this feature, your device must be rooted first.

But if you don’t exactly how to root your device, you can actually check out my article about how to root your Android device.

Bear in mind that if you root your smartphone or tablet, the 1-year warranty will be voided which means you cannot claim your warranty anymore at any service center.

Not to mention, there’s also another risk that you’re going to face here, like suffering a bootloop and even hardrick, which is more dangerous than losing the warranty.

So if you’re not ready to face these consequences, I strongly suggest you to not root your smartphone or tablet.

2. Download Droid Wall on Google Play Store. Okay, I assume that right now, you have managed to root your device. So what’s next?

Well, the next step you need to do is download an app called “Droid Wall” which you can download on Google Play Store.

This app is free but it requires root access of your device. So if you haven’t rooted your device, then don’t bother downloading this app because it’s not going to work.

3. Open the app and grant the root permission for this app. After you finish downloading and installing Droid Wall on your smartphone or tablet, now open this app.

Correct me if I’m wrong but usually, the very first time you open the app, it will ask your permission to allow the root access for this app. If that happens here, select “Allow” or “Grant” in the prompted window.

But if that doesn’t happen yet, then the system will probably prompt you that question later when you try to enable this app through the menu option.

4. Press the text on the top. So once you open the app, it will show you all the apps on your device in alphabetical order.

As you can see on the top of the list, there is the text that says “Mode: White List (Allow Selected)”. Now tap on it and change it to “Black List: (block selected)”.

By doing this, it will make it easier for you to pick which apps that you want to block from using the internet access of your device.

So if you want to block the apps, you can simply give check mark on 2 small boxes of each app, both WiFi and 3G. Or you can also tick off the 3G option so if you’re in WiFi-enabled area, you can still connect this app to internet using WiFi.

5. Press the menu option and enable this app. Once you finish giving check marks to all the apps that you want to block, now press the menu option so you can enable this app and start using it on your device.

However, there’s no button to open the menu option here on this app. So you must open it using the capacitive button that you usually use to open the menu option.

But if your device doesn't have the capacitive menu button, then I'm going to show you how to open the menu option using an app called Floating Toucher, of course in my next article. So be sure to stick around!

6. Enable the Firewall. Okay, if you finally manage to open the menu option, now enable this app by tapping on “Firewall Disabled” in order to change it to “Firewall Enabled”.

And once you press it, this option will turn color to green, which means this app is finally activated on your device. Usually, the system will automatically ask the root access for this app. If that happens, select “Allow” or “Grant”.

7. Press “Apply Rules”. After enabling this app on your device and you also have granted the root permission for this app, the next thing to do is press the option on the right that says “Apply Rules”.

And then, wait for a few seconds until the system applies the rules that you have set up before and start blocking some apps from using the internet connection of your device.

8. Exit the app. Okay, now exit the app because you’re good to go. As you can see, the apps that you have blocked earlier now won't be able to connect to the internet, which means DroidWall has worked properly.

Conclusion

Well, there you go guys, my secret trick to block the internet access on some certain apps by using DroidWall. Hopefully this app also works properly on your device.

I know that this app offers the same exact thing just like 'Data Saver' on Android Nougat OS. But if your device will not receive Android Nougat update, then you can still enjoy this feature through 'Droidwall' app.
