Unable to uninstall Greenify

You probably will never encounter uninstallation issue on recent versions of Android.

If you can't uninstall Greenify or the "Uninstall" button is grayed out, please open the Settings (or About dialog in older version) in main menu of Greenify, click the "Uninstall" entry if shown there. This will fix the uninstallation issue in most cases. If not, you can alternatively open your device Settings - Security - Device Admin (path may vary slightly on some devices), deactivate Greenify there. Then uninstall Greenify as usual.
