What Is CIDManager?

Samsung devices have a built-in application named CIDManager that’s causing a ton of issues. A lot of users have complained that this app sends a network service provider notification that cannot be removed.

We’ve found some Android forums claiming that the CID Manager app is used to manage the Carrier number of your Samsung Android device but this information isn’t entirely accurate.

In this article, I’ll explain more about the CIDManager app, what is it used for, why does it send notifications, and how to remove this notification.

What is CIDManager on Samsung Android Phones and What is it Used For?

CIDManager or Carrier Identification Manager is a preinstalled app on Samsung devices that checks if a device has access to country-specific Firmware updates by identifying the carrier network(service provider) as well as the device’s Original Design Manufacturing(ODM) country and matching it with the Country Specific Code(CSC) of the device’s Firmware.

For example, If you purchase a Samsung device from the United States and you use a SIM card from a network provider operating in the United States like T-Mobile or AT&T, then the CIDManager will match your device’s country of manufacture with the country of the carrier network.

Since both countries match the app will allow you to download Samsung Firmware updates intended for users in the United States.

Now, if the country of device manufacturer and carrier network doesn’t match then CIDManager will detect this and then provide a new configuration to tether the Original Design Manufacturing(ODM) country with the Radio Interface Layer(RIL) of the device with the help of the RilNotifier app.

This will allow the device to download global Firmware updates if your device supports Open Market Customization(OMC). Devices with OMC enabled can get OTA Firmware updates without depending on a particular Country Specific Code(CSC).

Every Android app has a unique package name that is used to identify the app. The package name of the CIDManager app is com.samsung.android.cidmanager.

CIDManager New Service Provider Notification Issue

The biggest problem with the CID Manager app is that it suddenly sends a "New Service Provider" notification on Samsung devices. This notification is mostly seen in Samsung Galaxy S8, S9, and Galaxy A6 but some other devices have also reported this issue.

This New Service Provider notification reads "Tap here to use your new service provider’s app and settings." When this notification is clicked, another popup appears that reads "To use your new service provider’s apps and settings, you need to factory reset your phone. All of your user data will be deleted, and some services may no longer be available."

The exact reason for this issue is not known but one possible reason could be that your Samsung device doesn’t support Open Market Customization(OMC), so when the CIDManager app tries matching the device’s ODM with the CSC, it gets stuck in a Loop and once the match fails it shows this notification.
