Netflix has stopped its app being available to many Android devices. The app has been blocked if it is detected that the device it is on has been 'unblocked' or 'rooted'. Netflix said that its Android app will no longer work on any devices that “are not Google-certified or have been altered.” Currently, if a user tries to download the app, a message will appear on the screen saying that the app is “incompatible with the device”. However, previously downloaded apps are reportedly still working. Unblocking an Android device has become commonplace amongst users who want to either download new updates before full release or delete pre-installed apps.
