5 Free Android Firewall Apps No Root Access Required
1. NoRoot Firewall – Android Firewall, Data Saver
NoRoot Firewall is an application that allows users to block access to the internet without the need for root access. This firewall enables users to individually permit or deny access to applications and addresses on both Wi-Fi and mobile connections. It aims to protect personal information from being sent to the internet by notifying the user when an app is trying to access the internet, allowing them to either allow or deny it.
The application has several benefits, including reducing data usage, saving battery, increasing privacy, enabling control over mobile apps, and facilitating easy blocking/allowing of app connectivity, among others. The app also allows users to block background app activity, receive alerts when new apps access the internet, and block adult websites.
NoRoot Firewall has several features that enable users to manage their internet access. These include the option to allow connectivity when the screen is on, block connectivity when roaming, and notifications for new applications. Users can configure InternetGuard directly from the notification, get full data usage visibility, and identify and notify when newly installed apps access the web.
Additionally, the app provides automatic launch of the device on startup, logs all outgoing traffic, and allows users to search and filter access attempts. They can also export PCAP files to analyze traffic and display a network speed graph in a status bar notification. Besides, the app allows users to block or allow individual addresses per application and has better VoIP support, supporting both IPv4/IPv6 TCP/UDP.
2. X Firewall (non-root, root, xposed)
The system offers users three distinct working modes: non-root, root, and xposed. Each of these modes provides users with a unique set of features and capabilities that they can leverage to customize their experience. In non-root mode, the system operates without any special privileges or permissions. This mode is ideal for users who prioritize stability and security over customization.
In root mode, the system grants users root access to the device. This mode allows users to perform advanced tasks like modifying system files, installing custom ROMs, and overclocking the device. However, root mode also comes with certain risks, such as the potential for bricking the device or compromising its security.
In xposed mode, the system uses the Xposed Framework to provide users with a modular approach to customization. This mode allows users to install modules that can modify various aspects of the device’s functionality, such as the look and feel of the user interface or the behavior of individual apps. Xposed mode is not as powerful as root mode, but it is much safer and more user-friendly.
3. NetGuard – no-root firewall
NetGuard is a firewall application that provides both simple and advanced ways to block access to the internet without the need for root access. The tool allows users to individually allow or deny access to applications and addresses for both Wi-Fi and mobile connections. The benefits of blocking internet access include reduced data usage, saved battery, and increased privacy.
The application boasts several features, including simplicity of use, 100% open source, non-tracking or analytics, actively developed and supported, and compatibility with Android 5.1 and later. It also supports IPv4/IPv6 TCP/UDP and tethering. Users can optionally allow access when the screen is on or block access when roaming, system applications, or in-app notifications. Additionally, the tool can record network usage per application per address and comes with a material design theme that offers both light and dark versions.
NetGuard Pro includes additional features such as logging all outgoing traffic, searching and filtering access attempts, exporting PCAP files to analyze traffic, and allowing or blocking individual addresses per application. Other features include new application notifications, configuring NetGuard directly from the notification, displaying a network speed graph in a status bar notification, and selecting from five additional themes in both light and dark versions.
Users can reach out to the developer via email or participate in the test program. The tool’s source code is available on GitHub, and all required permissions are listed in the FAQ. NetGuard is considered the only no-root firewall that offers this range of features.
4. NoRoot Firewall
NoRoot Firewall is a firewall app for Android devices that does not require the device to be rooted. It provides fine-grained access control based on IP address, host name or domain name, and has a simple interface that is easy to use. The app also has minimal permissions, with no location or phone number information being required.
NoRoot Firewall protects personal information from being sent to the internet by notifying users when an app is trying to access the internet, and allowing them to either allow or deny the connection. It allows users to create filter rules that allow or deny specific connections of an app.
Users of LTE may experience issues with NoRoot Firewall, as it does not currently support IPv6. The developers are working on a fix for this issue.
Translation contributors include numerous individuals, with the list including BjÃ¶rn Sobolewski, Torsten Bischof, and Jeanck, among others.
NoRoot Firewall is an ideal solution for users who want a firewall for their Android device without rooting it. It provides complete protection for Android users and is similar to Drodwall for non-root users.
5. DNS Changer (no root 3G/WiFi)
DNS Changer is an application that allows users to easily change their DNS and test the speed of DNS servers. The app does not require root access and works for both WiFi and Mobile Network Data Connection. The DNS Changer changes the device’s DNS address without affecting connection speed, making it faster than a regular VPN. Users can install DNS Changer for Android and try it themselves.
Changing DNS can provide several benefits for users, such as exploring freely on favorite sites and apps, browsing privately, staying secure on public Wi-Fi, enjoying the best net browsing performance, and having a better online gaming experience. The app provides an easy one-tap connection without requiring registration, login, or password.
Optimizing a device’s DNS records helps in finding the fastest routes for data packets to take when traveling the internet. It may result in a noticeable improvement in web browsing time. Slow hiccups in internet usage may be due to the provider’s DNS settings, as the ISP may not always have the best DNS server speed. Selecting the fastest server according to the user’s location helps speed up browsing. DNS Changer enables users to find the fastest DNS server and connect to it with just one touch, improving browsing speed and gaming experience. DNS settings will not affect internet download/upload speed, but response time.
The DNS Speed Test feature allows users to find and connect to the fastest DNS server based on their location and network. It improves web surfing speed with faster response time and fixes lag, reducing latency (ping time) on online games for better gaming experience. Users can improve their network connection with DNS Speed Test, find the fastest DNS server, and connect it with a single touch.
DNS Changer does not require root access, does not consume any system resources, and supports WiFi and Mobile Data Network (2G/3G/4G/5G). It also supports optional IPv4 and IPv6 DNS, tablet and smartphone, and preconfigured DNS lists.
