VPN Checker

A small android test app that allows you to see what other apps on your device can detect about your network settings.

Functionality:

Shows interfaces and their IP addresses Highlights whether a TUN, PPP, or WG interface exists in the system. Detects them in two different ways. Some apps, such as XPL-EX (XLuaPrivacy) https://github.com/0bbedCode/XPL-EX, can spoof certain parameters but not all of them, so this app helps you verify whether spoofing is working. Displays transport types and capabilities Shows which installed apps have VPN-related services Displays DNS servers Checks external public IP addresses (via direct connection and via TUN/PPP/WG interfaces, if the system allows it — only applicable to older Android versions) Attempts to detect default local SOCKS ports commonly opened by popular VPN apps and tries to retrieve the IP address through a SOCKS proxy Checks whether popular VPN apps are installed on the device Shows a full list of transport and network (deprecated) capabilities Provides a brief overview of potential privacy issues for VPN users.
