What happened to whole device mode for rooted Android devices?
Before December 2015 Psiphon for Android had a feature that allowed users with older Android devices (pre-4.0/ICS) to tunnel the whole device if it was rooted. A major update to Psiphon at that time necessitated the removal of that feature.
How do I configure applications to use the Psiphon tunnel?
Psiphon will automatically configure your system to use a local HTTP/HTTPS proxy and a local SOCKS proxy. The port numbers for these proxies are chosen randomly, unless specified in the Psiphon settings. Windows applications that use the System Proxy Settings will automatically be proxied. You may manually configure other applications to use these local proxies. Both Psiphon for Windows and Psiphon for Android run these local proxies.
Why do Android mobile hotspot and USB tethering not work through Psiphon?
This is due to a limitation in Android's hotspot and tethering implementation. You might find that either the tethered device cannot connect to the internet or the traffic will not go through the VPN.
How do I enable Android "sideloading"?
In order to install a direct download of Psiphon for Android, you must enable "sideloading". To do so, go into your Android settings, then into the "Security" section, then enable "Unknown sources".
Is my Psiphon for Android authentic?
Each Psiphon for Android client is shipped as an Android APK file (".apk") that is digitally signed by Psiphon Inc.
An APK may be validated by (1) extracting the certificate from the archive and checking that its fingerprints matches the value above and (2) verifying that the APK is signed with the certificate. For example, using Unix and Java command-line tools:
Psiphon for Android auto-updates itself, and this process automatically verifies that each update is authentic.
When Psiphon for Android first connects, why can't I select “I trust this application”?
Check if you are running a screen filter app or an app that manages your screen's brightness. If you are, try disabling it. Many of these apps (such as Lux Auto Brightness, Twilight, Night Mode) interfere with the user's ability to interact with this prompt.
After upgrading the Psiphon for Android app, it won't connect.
If Psiphon is connected while an upgrade is installed, it may not be able to connect afterwards and will show the error “start_tunnel_failed application is not prepared or revoked”. This is due to an Android OS bug. This condition can be fixed by rebooting your device.
Why does my Psiphon connection sometimes disconnect?
This is most commonly caused by an unreliable or inconsistent Internet connection to your device or computer. On a phone, this can mean losing reception. On a computer, this can mean inconsistent Wi-Fi or an unreliable Internet Service Provider.
Why do I see the message "connection failed" repeating over and over?
If you see repeated "connection failed" messages, it means that there are no available servers that your client knows about. Try to download a new Psiphon client.
