Openvpn for Android is a cost-free application that can be used on any device running Android 4.x or later. It utilizes the Android system API and doesn’t require numerous permissions. It is important to know that openvpn for Android is not a VPN service by itself, it’s an application that connects users to a VPN server. It must be a server ‘on the other end of the line’ in order for it to function.
You will need the NordVPN Account, the NordVPN App installed on your device, as well as the configuration files for the server location you have selected. Our recommended VPN providers provide downloads of their configuration documents for different locations. Download the config file to your phone or computer and transfer it over to your device using an SD-card/USB/Dropbox. Once the file is installed on your device, install the free OpenVPN Connect application by Arne Schwabe from the Google Play Store.
OpenVPN Connect, the “official” client of OpenVPN Inc., is designed to be user-friendly and easy to use for novice VPN users who do not have the technical knowledge. It’s not as feature-rich as openvpn for Android and is intended for more advanced users. Both apps let you connect to any VPN service that is compatible with the OpenVPN protocol, but openvpn for Android has a more intuitive UI and is compatible with more devices. It also has features like dynamic IP addresses, split tunneling, and more that aren’t included in the official OpenVPN Connect application.
