I have installed the VPN on my Samsung S7 mobile phone but I am unable to connect it. When I turn it on it states "Masking Connection and location" and then closes the process to leave me with the "VPN is off" screen. I realise that it's a phone setting so if I then scroll to Home Screen Settings Connections More Connection Settings VPN (set up and manage VPNs) Add VPN I am then asked for VPN Network type (PPTP is suggested) but it then asks for the server address. I assume that this is the VPN server? Any ideas on how I can resolve this? Orbot VPN works OK straight away.
