In Android, you can easily toggle between mobile data and WiFi or even turn it off entirely as and when needed. However, Android doesn’t offer any options whatsoever to better manage what apps can and cannot connect to the internet or how they connect. That doesn’t mean you cannot vet and control how your device is connecting to the internet. We are talking about Android here, there is an app for everything.
Disable Internet access for certain applications in Android?
If you are running Android N or higher, you can block apps from accessing the internet in the background from the app settings. Simply go to Settings > Apps, select the app you want to block background internet access Next, tap “Data usage” and enable “Restrict app background data”. Now, no apps will be able to use the Internet while they are running in the background.
However, if you open the app, it will use the internet. And this is where Firewall apps come into the picture. So, here are some of the best firewall apps to manage internet access to the apps on your Android device.
Best Firewall Apps for Android
1. NoRoot Firewall
When it comes to a firewall for an unrooted Android device, NoRoot Firewall is one of the best in terms of features and the control you get. In fact, if you read my articles, this is not the first time I talk about NoRoot Firewall, partly because I personally use it from time to time. With NoRoot Firewall you can control what apps can and cannot connect to the internet. For finer control, you can restrict apps from connecting to the internet over WiFi or mobile data with just a single tap. Other than that, you can also block access to the websites and IP addresses of your choice.
As good as it, NoRoot Firewall doesn’t yet support IPv6 addresses. So, it may or may not work on LTE connections. Also, the app can be overwhelming for new or beginner users due to all the options and filters. So, give yourself some time to configure NoRoot Firewall in Android.
Price: Free, no ads, and no in-app purchases.

NetGaurd is very similar to NoRoot Firewall in that you can block individual apps from access the internet via mobile data or WiFi. Compared to NoRoot Firewall, the notable things about NetGaurd is that it has a much cleaner user interface, better settings management, and most of all, it is open source. With just a single tap, you can either block entire network traffic or on a per-app basis. If need be, you can also block specific address for specific apps. Apart from that, NetGuard has other advanced options like the ability to filter IP packets, log internet access, manage internet access to system apps, app whitelisting and blacklisting, etc.
If you are looking for a free, open source, and feature filled app then NetGaurd is for you.
Price: Free and contains ads. Some advanced features are locked by default and you can unlock all of them or an individual feature with in-app purchases.

3. AFWall+ (requires root)

Using AFWall+ you can control internet access on a per-app basis, be it system apps or installed apps. The app is very simple to use and has a ton of options to configure it the way you want.

4. Mobiwol: NoRoot Firewall
Mobiwol app lets you block individual apps from accessing the internet either through WiFi or mobile data. The appeal of Mobiwol is that it is very easy to use and there are no complicated settings to deal with. Just select the app you want to block the internet connection and you are good to go. You can block both system and installed apps. One thing I really like about this app is that you can see how much data each app is consuming and you can restrict the individual app from using only a specific amount of mobile data. Once the app reaches that limit, it will not be able to access the internet via mobile data.
So, if you don’t want to deal with all the advanced options and confusing settings and just want to block a few apps from accessing the internet then give Mobiwol a try.
Price: Free and contains ads.

5. NoRoot Data Firewall
NoRoot Data Firewall has a very clean user interface. By default, the app is configured to notify any app that tries to access the internet. You can select either to allow or block the access accordingly. Of course, you can also control access based on individual apps, default behaviors for WiFi and mobile data. The other good thing about the app is that it logs network interactions of all the apps. Just tap on the app and select the “Analyze” option to see what websites or IP address a particular app is connecting to. Apart from that, you can block individual domains or IP addresses, block images from loading to save data, modify DNS server, throttle bandwidth, capture packets, and password protect NoRoot Data Firewall and its settings.
Price: Free, contains no ads and in-app purchases.

Using this app, you can not only block apps from accessing the internet over WiFi and/or mobile data but can also restrict apps from connecting to any country or region. Just like with all the other non-root firewall apps, LostNet NoRoot Firewall uses local VPN to manage the network traffic. As such, it can also block ads and protect your device from any malicious domains or websites. One of the best things about LostNet NoRoot Firewall is that you can configure it to automatically block all apps from accessing the internet while you are sleeping, i.e, at night time or on your own schedule.

Of course, you can control both the mobile data and WiFi individually on a per-app basis. Unlike other apps, NetPatch Firewall lets you configure whether the apps can or cannot connect to the internet while the screen is off. This feature is very useful when you want to tame apps from connecting to the internet when you are not actively using your smartphone. As soon as you unlock your device, apps can connect to the internet.
Other features of the app include but not limited to the custom DNS server, ability to create the domain and IP groups, detailed logs, block specific IP addresses or domains, etc.
