Configure VPN for Android

Here I will try to talk about setting up a VPN on android devices.
Many users have never heard of a VPN, and when they saw this item in the phone’s settings, they simply shrugged their shoulders and passed on. If you know what a VPN is, how it works, then most likely this article will not tell you anything new, I wrote it for beginners who want to protect their security on the network, circumvent censorship and regional restrictions, and maintain their anonymity.
So what exactly is a VPN?
VPN - (Eng. Virtual Private Network - a virtual private network) - a generic name for technologies that allow one or more network connections (logical network) over another network (for example, the Internet).
PPTP VPN- PPTP (English Point-to-point tunneling protocol) - a point-to-point tunneling protocol that allows a computer to establish a secure connection to a server by creating a special tunnel in a standard, insecure network. PPTP places (encapsulates) PPP frames in IP packets for transmission over a global IP network, such as the Internet. PPTP can also be used to tunnel between two LANs. PPTP uses an additional TCP connection to serve the tunnel. PPTP traffic can be encrypted using MPPE. Various mechanisms can be used to authenticate clients, the most secure of them are MSCHAP-v2 and EAP-TLS.
My task in this article is not a detailed story about VPN (what it is, how it works, where it came from) information you yourself can take here:ru.wikipedia.org/wiki/VPN

Orbot: Tor for Android - play.google.com/store/apps/details?id=org.torproject.androidTor is an open-source cross-platform software aimed at protecting against “listening” and ensuring the confidentiality of personal and business data transmitted over the global network. The product provides complete anonymity of customers when visiting websites, publishing materials, sending messages and working with applications that use the TCP protocol. Users of the Android platform have already been given the opportunity to use Tor proxy networks for anonymous surfing. Some time ago, a group of researchers from Cambridge University released a product called Shadow. The new Orbot application is the official version of the Tor client from the creators of the platform. Tor on wikipedia en.wikipedia.org/wiki/Tor
