CIDManager is a framework program that isn't required by the stock ROM. It was introduced to the majority of clients via an OTA update. It is not recommended that you uninstall it from your device because it is a framework application. Uninstalling it may result in some issues, and your device may become unstable. In any scenario, CIDManager-dependent programs and administrations will no longer function effectively. Furthermore, this can cause additional inner difficulties. In any event, you can always use the previously described safe uninstalling procedure. Consider how your Samsung phone responds. Because each telephone is unique, uninstalling, or crippling it is unlikely to cause additional problems in your circumstance.
