Setup Captive Portal Check
In this article, you will learn how to set up your own captive portal check on different devices.
Android
To change the Captive Portal Check in Android, you need a terminal app or a connection via ADB to a computer.
To use http you can run the following commands with the respective method:
# settings put global captive_portal_use_https 0
# settings put global captive_portal_http_url "http://connectivitycheck.sp-codes.de/generate204"
To use https you can use the following two commands:
# settings put global captive_portal_use_https 1
# settings put global captive_portal_https_url "https://connectivitycheck.sp-codes.de/generate204"
Maybe you have to reboot your phone after updating the settings.
If you are using AFWall+ you need to give access to [1000] Android-System and in some cases [10040] CaptivePortalLogin to make it work.
