Supported on versions 2.3 through 4.3, including Kindle Fire, CyanogenMod, and Intel.
While Android itself is "open", the devices that run it often aren't. Before installing Substrate, you will first need to get root access on your device.
Depending on which device you have, and which version of Android, this process differs; we therefore can't provide a simple recommendation.
Once you have root, you will need to install our APK, run the application, click Install, and grant Superuser access to Substrate when prompted.
