Firewall Apps for Android: In Android, you can easily toggle between mobile data and WiFi. You can also turn it off entirely as and when needed. However, Android doesn’t offer any choices to better manage what apps can and cannot connect to the internet or how they connect. That doesn’t mean you cannot control how your device is connecting to the internet.
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. Just go to Settings > Apps, choose the app you want to block background internet access then, tap “Data usage” and allow “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’ll 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
When we talk about the firewall for an unrooted Android device, NoRoot Firewall is one of the best in terms of features and the control you get. With the help of the NoRoot Firewall, you can control what apps can and cannot connect to the internet. You can also restrict apps from connecting to the internet over WiFi or mobile data with just a single click. 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 support IPv6 addresses. So, it cant work on LTE connections.
