The CyanogenMod Installer application for Android Devices was found in Violation of the Google Play Terms and Conditions and was asked to be removed by Google. The application provides a single function to guide users to enable Android Debug Bridge (ADB), a built-in development tool that allows a user to sideload via a desktop installer that can be used to install the CyanogenMod OS on your Android device.
CyanogenMod stated via their blog
After reaching out to the Play team, their feedback was that though application itself is harmless, since it ‘encourages users to void their warranty’, it would not be allowed to remain in the store.
Google provided CyanogenMod with the option to pull the application voluntarily or they would be forced to remove the application from the Play Store. CyanogenMod has obliged and pulled the application out of the PlayStore.
CyanogenMod is the most popular non-OEM Android experience and the application in the PlayStore had simplified the process so even the non-geeks could easily install the OS on their Android Devices. CyanogenMod appreciated the open nature of the Android Platform and continue to make the application available for installation through their website. The application will be submitted to other App Stores such as Amazon and Samsung App Stores for easier installation in future.
