Openvpn for android is a free application that runs on any device running Android 4.x (Ice Cream Sandwich) or later. It uses the Android system’s API and does not require numerous permissions. Openvpn for Android does not function as an actual VPN itself, but a client that connects to an VPN. It needs to connect to one on the other side of the line’ for it to work.
You will need to have an NordVPN account, the NordVPN app installed on your device, and the necessary config files for the server you choose. Our recommended VPN providers make this simple by providing downloadable config files for all of their locations. Download the configuration files to your computer or phone, then transfer them to your device through USB/SD-card/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 by casual VPN users who lack technical skills. It’s not as feature-rich as openvpn for Android which is designed for more advanced users. Both apps allow you to connect to any VPN service that supports the OpenVPN protocol, but openvpn for Android has a more intuitive UI and is supported by a greater number of devices. It also supports features such as dynamic IP addresses, split tunneling and more that are not available in the official OpenVPN Connect application.
