Mobile games often require a constant connection to the network, but there are situations when this gets in the way. For example, you want to save bandwidth, remove intrusive ads, or just focus on gameplay without distractions. In the operating system Android there is no one universal button “Disable Internet for an application”, however, there are effective workarounds.
In this article we will analyze in detail all the available methods for limiting network access for specific games. You'll learn how to use built-in system features, third-party utilities, and even developer tools. The choice of method depends on the version of your firmware and the availability of root access.
Some methods require preliminary preparation, for example, enabling developer mode. Others work out of the box on modern smartphones. Let's look at each option so that you can choose the most suitable one for your device.
Using built-in Android settings
Starting with version Android 7.0, the system has a function for limiting data transfer in the background, and in newer versions (Android 9 and higher) the settings have become even more flexible. This is the safest method and does not require installation of additional software.
To use this method, you need to go to the settings menu of your smartphone. Find the section responsible for connections and traffic management. The interface may differ depending on the manufacturer's shell, for example MIUI, OneUI or Pixel UI.
Inside the traffic management section you will see a list of all installed applications. Find the game you need in this list. Click on it to open detailed information about data consumption.
- 📱 Go to
Settings → Connections → Data usage. - 🎮 Find the game in the list and tap on its name.
- 🚫 Disable switch “Allow background data use.”
- 🔒 Some skins have an option to “Prohibit data use” (Mobile data & Wi-Fi).
If you turn off only background data, the game will still be able to connect to the network when it is open on the screen. To completely block it, you need to find a checkbox that prohibits access to mobile data and Wi-Fi at the same time. On some devices, this option is hidden in the "Background Limit" submenu.
⚠️ Warning: Disabling network access completely may cause the game to stop launching or constantly display a connection error if it requires online authorization.
If the game requires login through Google Play Games or Facebook, disabling the Internet may cause a crash authorization. Try logging into your account before access is blocked.
After applying the settings, try starting the game. If it loads, but does not show ads and does not try to synchronize saves, then the method worked correctly. This is a standard solution that does not violate the device’s warranty.
Blocking via airplane mode and Wi-Fi
The most radical but effective method is to completely disable all network interfaces before launching the application. This method ensures that not a single byte of information leaves your device.
Activate the “Flight” mode in the notification shade or through the settings. Make sure the airplane icon appears in the status bar. After this, the system will forcibly terminate all active connections.
However, there is a nuance: many modern games check for the presence of a network at startup. If there is no connection, they may get stuck on the loading screen or crash. In this case, you can try the Wi-Fi trick.
- Turn on airplane mode.
- Manually turn on only Wi-Fi (if the game requires a local network) or leave everything turned off.
- Start the game.
- If the game requires a network, it may throw an error - this normal.
For games that work completely offline, this method is ideal. It also helps avoid sudden updates that can start in the background and take up all the RAM.
Use of third-party firewalls
If the built-in system tools are not enough, specialized applications - firewalls - come to the rescue. They allow you to flexibly configure access rules for each application separately.
The most popular solution is the application NetGuard. It does not require root access and uses the capabilities of the VPN service on the device to filter traffic. The entire data flow passes through the local application interface, where the decision to block is made.
After installing and configuring the firewall, you will see a list of all apps. Opposite each of them there will be Wi-Fi and mobile network icons. Clicking on the icon changes its status to blocked.
| Application | Root required | Lock type | Setting complexity |
|---|---|---|---|
| NetGuard | No | VPN filter | Low |
| AFWall+ | Yes | iptables | Average |
| NoRoot Firewall | No | Local proxy | Low |
| Mobiwol | No | Monitoring | Average |
The use of such apps has its own characteristics. Since they create a local VPN connection, you won't be able to use other VPN services at the same time. This is an important limitation that is worth remembering.
⚠️ Attention: When using firewalls without root access, the battery may drain faster due to the constant processing of network traffic in the background.
For advanced users with superuser rights, the utility AFWall+is suitable. It works directly with the system kernel through iptables, which ensures minimal impact on performance and autonomy.
Editing the hosts file for advanced users
This method is intended for advanced users with root access. The file hosts in the Android system is responsible for mapping domain names to IP addresses.
The essence of the method is to redirect all game requests to the local address of the device. Thus, the game “thinks” that it has connected to the server, but in fact the connection goes nowhere.
To implement this, you will need a file manager with root access, for example Root Explorer or Solid Explorer. Find the file at the path /system/etc/hosts.
127.0.0.1 adserver.game.com
127.0.0.1 analytics.game.com
You need to add lines where the IP address 127.0.0.1 is mapped to the domains that the game uses. You can find out these domains using traffic sniffers, such as Packet Capture.
How to find the domains of a game?
Install the Packet Capture application, start recording traffic, open the game and perform actions that trigger a network request. In the log you will see the server addresses.
After editing the file, be sure to save the changes and restart the device. This method is very effective for blocking ads, as it blocks access to advertising networks at the system level.
Using USB and ADB debugging
If you do not have root access, but want to gain control over network access at a level close to the system level, you can use debugging tools ADB (Android Debug Bridge).
To do this, you need to enable the mode developer on a smartphone. Go to Settings → About phone and quickly click 7 times on the build number. Then, in the new menu, activate “USB Debugging.”
Connect your phone to the computer and run the command to revoke network access permissions. This does not work for all applications, as it requires the application to support this flexibility in the manifest.
The command looks like this and is entered in the computer terminal:
adb shell pm revoke com.package.name android.permission.INTERNET
Replace com.package.name with the actual batch ID of your game. You can find it out in the application settings or through utilities like App Inspector.
⚠️ Attention: Revoking permission INTERNET may lead to unstable operation of the application. Some games may crash immediately when trying to initialize network modules.
To restore access back, use the command with the parameter grant instead of revoke. This method is good because it does not require installing unnecessary applications on the smartphone itself.
☑️ Preparing to work with ADB
Possible problems and solutions
When blocking access, you may encounter a number of difficulties. The most common problem is that the game refuses to start or the loading indicator spins endlessly.
This means that the developers have strictly prescribed connection checking. In this case, completely disabling the Internet is impossible without modifying the game file itself (APK), which is a complex procedure.
Another problem is the loss of progress. If the game saves data only in the cloud, then when working offline, your progress may not be saved or will be overwritten by the old version the next time you connect.
- 📉 The game crashes at startup - try giving access only to Wi-Fi, turning off mobile data.
- 💾 Progress is reset - make sure that the game supports local saving.
- 📢 The advertisement still appears - it may be cached, clear the application cache.
It is also worth considering that Android interface updates may change the location of menu items. What worked on Android 10may be called differently on Android 14.
If standard methods do not help, the only solution is to use modified versions of games or patches, but this carries security risks.
Frequently asked questions (FAQ)
Is it safe to use third-party firewalls?
Using proven open source applications like NetGuard is safe. However, avoid dubious apps from unknown sources, as they can intercept your traffic.
Does blocking the Internet affect the operation of other applications?
When using built-in settings - no, restrictions apply only to the selected game. When using VPN firewalls, other applications work fine unless you block them manually.
Is it possible to block access only to the mobile data, leaving Wi-Fi?
Yes, in the data usage settings of most modern smartphones there are separate switches for “Mobile data” and “Wi-Fi” for each application.
Why does the game require the Internet, even if I play in single player mode?
Developers often build in analytics, anti-cheat systems, and advertising modules that require a constant connection to check licenses and collect statistics.
Will a system update reset blocking settings?
A system update usually does not reset application permissions settings. However, third-party firewall settings may be reset when wiping system data or performing a factory reset.
