If you have a large number of apps on your phone, they will continue to consume precious network resources. For example, gaming apps like PUBG can hog internet speeds in the background. Therefore, you may want to block their internet access completely. The idea is to be selective in assigning the internet to your choice of Android apps and turning it off when you don’t need it.
It is possible to restrict the access of certain Android applications to your mobile data, but not to Wi-Fi. This is a measure taken by Google to ensure that all applications on your system connect to the Internet as soon as possible. you turn on Wi-Fi. You will learn how to bypass this system restriction and turn off all forms of Internet access for apps you don’t want to remove at this time.
Reduce internet access from settings
If your goal is only to minimize internet usage for apps and not shut it down completely, there are some common methods you can try. With Android 7.0 or higher version, you can use its data saving feature. To access it, go to “Settings -> Network & Internet” and select the Wi-Fi network. On some phones, it may be seen as an icon.
The data saver menu has a toggle switch that stays off. As soon as you turn it on, you will see a list of apps with internet access that can be controlled.
By activating the data saver, you can stop automatic playback of videos and automatic downloads and restrict unnecessary images.
For additional restrictions, you can also turn off location access for all apps when not in use and reduce background data usage.
Completely block internet access for some apps
To completely block Wi-Fi as well as mobile data access, you will need to download a Play Store app called NetGuard – no root firewall. It is one of the best apps to block online access to any app without rooting the phone. There are no ads, trackers, or other privacy concerns.
For travelers roaming abroad, the app allows you to block system apps. The app supports Android 5.1 and above.
As soon as you open the app, you will find that Netguard is disabled. Activate the toggle switch. It will activate a “VPN” type function, which is used to enable or disable Internet access to various applications.
You will notice two colors for the network icons: a greenish tint and a reddish tint, which means “on” and “off” respectively. These will be displayed prominently next to each application. All you have to do is tap the icons to turn the internet on and off as you need. By default, the icon is always green for “Wi-Fi” on the left and “mobile data” on the right.
In some cases, especially for messaging apps like Slack, the incoming message is received by Google Play services and not directly by the app. Therefore, you should turn off the Internet for the messaging app as well as for the Google Play services.
In other cases, Internet access to the app is controlled by Download Manager, for example, in the case of YouTube, Zoom and other video / video conferencing applications. Fortunately, NetGuard supports all system applications.
To restart internet access for apps again, just turn the Wi-Fi and mobile data icons green again. The app also performs additional tasks such as blocking ads and keeping a log of exactly when the phone connects to the internet. Finally, if you have limited Wi-Fi bandwidth, you can set a metered Wi-Fi connection on your Android phone.
