Simple, scalable, cross-platform and effective solution against government censorship for Android
The Android version of PowerTunnel is built on VPN Server that intercepts traffic and directs it through the LibertyTunnel proxy
Nowadays Internet censorship is introducing in many countries: governments analyze and block traffic to this sites using DPI - Deep Packet Inspection systems, forcing you using circumvention utilities like VPN, for example. That approach have many disadvantages, most noticeable - connection speed slowdown. In addition, these services cannot guarantee work stability and your data confidence.
PowerTunnel for Android is active DPI circumvention utility, that works only on your phone and don't send your traffic to third-party servers, respecting your privacy and do not slowing down your internet connection.
Since PowerTunnel for Android uses the same architecture as the PC version, the Android version also uses proxy server - it lies under the VPN service and running at 127.0.0.1:8085, so you can setup PowerTunnel in ways other than VPN.
PowerTunnel for Android establishes a transparent proxy server on your phone and starts local VPN server, that forwards your traffic into the proxy server, where are DPI circumvention tricks applying.
You can compile a binary yourself or download prepared binary here.
Just install it as a regular Android application: no root access is needed.
PowerTunnel for Android provides various ways to configure DNS lookup and host name resolving. It's not recommended to change PowerTunnel's DNS settings if you don't have valuable reasons to to that because it can be unstable and slowdown your Internet connection.
You can enable DNS over HTTPS (DoH) mode in the settings - enable DNS override and select provider with the DoH label.
All available DoH providers are tested and fully compatible with PowerTunnel, you can also specify your favorite server.
You can check does DoH work there.
If you try to determine your DNS here you'll get nothing due to the internal architecture of PowerTunnel Android version, even though X actually works.
At the moment, DoH doesn't work on some of Android 10 and higher devices. If you're experiencing the same problem, please, submit your phone vendor.
DNSSec mode appears to validate DNS responses.
DNSSec mode is experimental and not recommended to use. Note that it useless and not working when DoH mode is enabled (because DoH already validating DNS responses on server-side). When there's some troubles with resolving, resolving is going on with the system's DNS settings.
You can also choose one of custom DNS providers (without DoH). It doesn't work with some of Android versions.
When there's some troubles with resolving using the choosen custom provider, resolving is going on with the system's DNS settings.
Just type its address in the settings. If the address starts with https:// it will be recognized as a DoH provider.
Most likely your ISP blocked the website you need by IP address, so only encrypted tunnel (VPN/Tor) can help you.
Also, you can try enabling full chunking mode.
PowerTunnel is open-source software: you can help in the development process.

You can also help by translating PowerTunnel to your language.
