What Is DiagMonAgent? and Why Does It Keep Stopping?

Throughout this post, we’ve covered the basics: what is DiagMonAgent, why it’s useful, and how to avoid it from crashing.

What Is DiagMonAgent?

Samsung smartphones have an app called DiagMonAgent (Diagnostic Monitor Agent) that is part of Android’s system software.

Its purpose is to identify problematic software and provide feedback to programmers. As was already shown, the widespread belief that this is malicious bloatware or that the user’s phone has been compromised is groundless.

What Is DiagMonAgent

Further details, such as how to resolve the halting problem, are provided below for your convenience.

What Access Does DiagMonAgent Require?

If you don’t want DiagMonAgent to work, you must provide it access to your phone’s telephone features, even if it utilises this permission for no other purpose.

Does DiagMonAgent Have Any Value?

DiagMonAgent is capable of much more than simply programme diagnosis. You may manually check the proximity, lights, gyroscope, fingerprint, accelerometer, magnetic, and touch screen of your smartphone.

Simply dialling *#0*# from your phone’s dialer will launch the device’s diagnostics app.

DiagMonAgent-related problems

Here are some of the common problems:

1. Notification Reporting Upon Wi-Fi Activation

DiagMonAgent requires access to your phone’s phonebook whether or not you choose to share this information with the app.

After enabling Wi-Fi, the DiagMonAgent app will submit a report, which will be shown in the notification drawer as “sending report” on Android 5.0 and later.

We don’t know for sure what kind of report it sends to the system administrators, but we think it involves communication with other applications.

Some users may find the alert intrusive, however, it is necessary for the proper operation of the DiagMonAgent. Seeing it once after turning on Wi-Fi is normal; but, if you’re seeing it often, something is amiss.

2. DiagMonAgent Is No Longer Sending Messages

A common problem with Samsung devices, including the Galaxy S6, is receiving a notification saying that DiagMonAgent has ceased.

Having the notification pop up all the time, especially when people are trying to get anything done, is a major pain. In case you are experiencing this problem, we will explain possible solutions in the next section.

The solution to the “DiagMonAgent Has Stopped” Error?

Unroot your device if it is rooted and check for firmware updates before attempting to repair this problem using any of the techniques described in this article.

As a first resort, try to solve the problem without having to delete the programme by using Force stop or another simple remedy.

Can DiagMonAgent Be Deactivated Without Harm?

Yes, however unless absolutely necessary, we advise against temporarily or permanently deleting the app. Avoid erasing the app and flashing its original firmware if none of the other solutions works.

Using a firmware flashing programme like Samsung Odin, you can restore the device to factory settings in a matter of minutes.

1. To Force Stop & Clear Cache and Data

Although clearing cache and data and then Force stopping the programme has a low likelihood of curing the problem, it just takes a few minutes and may be done in conjunction with other solutions.

  • Check the device’s settings.
  • Try searching for “Apps” and selecting it.
  • Choose the Ellipsis button (three dots on the top right corner).
  • Select the system applications to display the menu.
  • Click the DiagMonAgent button.
  • Finally, choose Clear data to permanently remove all data and clear the cache.

2. Reset Your Device to Factory Settings

Be aware that all of your data, including any applications you may have downloaded, will be lost if you do a factory reset.

If you want to restore your smartphone to its original settings without losing any of your data, you should attempt the “Reset settings” option before doing a full factory reset.

An appropriate placement for the “Rest settings” option would be at the top of the menu where the factory reset choice is found.

  • Adjust your device’s settings.
  • Select “Top-level management”
  • You may start again by selecting the “Reset” button.
  • If you open a window on your smartphone and then tap “Factory data reset,” you will get a list of everything that will be deleted.
  • If you have a screen lock enabled, you’ll need to confirm it before you can reset the device.
  • In the end, your device will restart, and hopefully, you won’t encounter the “DiagMonAgent has stopped” warning again.

3. Take down DiagMonAgent

Remove the DiagMonAgent app from your device using the system’s built-in uninstaller or the Android Debug Bridge if steps 1 and 2 fail (ADB).

How to uninstall DiagMonAgent App?

1. Use Android Debug Bridge (ADB)

You may issue instructions to your smartphone with the help of Android Debug Bridge (ADB). If you’re not very tech-savvy, using ADB could seem like a daunting task, but it’s really rather simple if you follow the instructions below.

If you don’t have access to a computer but still need to uninstall DiagMonAgent, then you may use the second approach. ADB is required in order to delete the software.


  • Select “About phone” from the device’s settings menu.
  • By tapping the build number seven times, you may access the Developer Options menu.
  • Return to the previous screen and choose Developer Options.
  • Disable normal operation and activate debugging via USB.
  • Get ADB onto your PC.
  • To unpack the ZIP file, first, create a new directory to store the files.
  • Once the archive has been extracted, open that directory.
  • Click the right mouse button while holding down the shift key.
  • To launch the Powershell prompt, choose the option to “Open Powershell window here.”
  • Type in the command ADB devices.
  • Cable in your Android mobile to your computer.
  • To uninstall com.sec.android.diagmonagent, type ADB shell pm uninstall —user 0 and hit enter.

2. Remove System Apps (Root Needed)

  • Get rid of apps on your device’s operating system by downloading and installing the appropriate tool.
  • Open the programme and look for DiagMonAgent.
  • Select the app by checking the box next to it.
  • The last step is to click the Uninstall button.

In order to use this approach, your Android smartphone must be rooted; if it isn’t already, you may do so by using Kingoroot (available for both Android and desktop computers).
