Root My Galaxy is an Android app that installs root access on a specific list of supported Samsung Galaxy phones. Rooting means unlocking deeper control over the phone's operating system, something Samsung normally blocks. The app relies on KernelSU, a system for managing root access, and on a known security flaw in certain Samsung firmware builds that lets the installer get in. The project keeps two things separate. The app itself, which you build and run, lives in this repository. The actual per-device data it needs, meaning offsets, exploit payloads, and prebuilt KernelSU files, lives in a companion repository called Root-My-Galaxy-Payloads. This split keeps the app lightweight while the device-specific pieces update independently as new firmware builds are added. When you open the app, it looks at your phone's exact kernel release, full build ID, SDK version, processor type, and memory page size, then automatically picks the matching profile for your device. There is also an advanced mode where you can choose a profile by hand instead of relying on the automatic match, along with warnings if the kernel release or build does not line up cleanly. To build the app yourself you need Android Studio's JBR 21, Android SDK 37, Android NDK 28 or newer, and CMake 3.22.1. The README gives a short PowerShell command to compile a debug build with Gradle, which produces an APK file you can install on a phone. The README is direct about scope: this only works on the specific Samsung firmware builds it explicitly supports, not Samsung phones in general, and the author states plainly that it should only be used on devices you own or have clear permission to test. There is no discussion of warranty, support channels, or a broader roadmap in the README itself.
