Microsoft Endpoint Manager, Debugging Android Devices

When managing devices at some point there will be some sort of issue that requires a deeper level of troubleshooting. Additionally, learning how to debug a device is not a bad thing, in fact anyone can do this. In this months post I dig into logging and debugging Android devices enrolled with Microsoft Endpoint Manager. There are several tools that can be utilized to troubleshoot Android devices and as with most troubleshooting, it’s a process of peeling back the layers until the issue is found and remediated.

Let’s get started!

Debugging Tools

For devices enrolled with Microsoft Endpoint Manager (MEM) I recommend starting with the Troubleshooting section within the MEM Intune console. It provides a consolidated view of policies, apps, compliance, and much more. Start with the troubleshooting console and work forward. If the troubleshooting information doesn’t reveal what you’re looking for we can head over to the device for direct troubleshooting.

Device Policy Controller (DPC)

There are various enrollment methods Goole offers for Android devices, such as Device Admin, Work Profile, and Device Owner. For the purposes of this post, I’m going to focus on Device Owner (Android Enterprise), however these methods may be applied to other enrollments as well.

When devices are enrolled with MEM they utilized what is called a Device Policy Controller (DPC). The DPC is automatically installed on the device during enrollment. Once enrolled, locate the DPC app by navigating to Google Play and selecting and opening the Android Device Policy app. From there you can sync the device and view which apps were installed and policy settings.

If you’re using the Managed Home Screen (as shown below), tap on the back arrow several times (ok 15 times) and on the menu select “Launch Android Device Policy app” which takes you to the DPC app where we can view and sync policy.

Note: the process above may not work (and probably doesn’t) for other EMMs who create their own DPCs.  The process is specifically for the CloudDPC Google provides for EMMs utilizing the Android Management API (which MEM does).  As such, contact Google to provide feedback about other debug features you may need in the CloudDPC.

Enable debugging in the DPC

I was poking around settings and I discovered a really helpful option for devices enrolled with MEM. Open the Android Device Policy app and select the three dots in the upper right hand corner > select device details > scroll down and look for “Model” and tap until debug items is enabled. Back arrow to the Device Policy screen and select the three dots in the upper right hand corner again, then check the box next to “All policies“.

You’ll now see all the policies deployed to the device from MEM including policy version, apps, settings, etc. This may be enough to work through issues, however if deeper investigation required read through the sections below.

Device debugging

We will need to do a few things to set up debugging, first we’ll need to enable debugging on the device and then install some tools provided by Google.

Enable developer options and USB debugging

  1. Under Settings search for “About phone” and tap > now find and tap “Build number” until is says “You are now a developer!”
  2. Next under Settings search for Developer and select developer options (System > Developer options) and is should show as On.
  3. Find and enable “USB debugging”
  4. Enable/disable settings you need to under the settings then connect to USB.

Android Debug Bridge (adb)

On a Windows, Mac, or Linux device navigate to and install the Android SDK Platform-Tools package.

Direct download link:

Log collection and debugging devices

Connect your device via USB (you can also connect via WiFi as well), open a cmd.exe window (I’m using Windows btw), navigate to the directory where the SDK was installed and type in adb.exe devices -l

If you receive an error, run the following commands:

adb kill-server

adb start-server

This should kick things off, assuming the device is enabled for debugging.

Another issue is debugging authorizations, if you run into issue here, do the following: Revoke USB debugging authorizations – when you attach this will prompt for authorization again otherwise you may receive “unathorized” in the command line

Run adb.exe devices -l again and you will see the following (in my case I have a Zebra attached):

List of devices attached

18359522505742 device product:TC57 model:TC57 device:TC57 transport_id:1


Collecting logs

Run the following commands to collect logs to be utilized in troubleshooting:


According to Google developer docs: “Logcat is a command-line tool that dumps a log of system messages, including stack traces when the device throws an error and messages that you have written from your app with the Log class.” Google also has a tool that developers may build to read app logs:

  • From the command line run: adb.exe logcat -v threadtime [device ID] > C:\temp\android.log


According to Google developer docs: “A bug report contains device logs, stack traces, and other diagnostic information to help you find and fix bugs in your app.”

  • From the command line run: adb.exe bugreport c:\temp\ – open the file named “bugreport…….txt”   

    e.g. bugreport-TC57-01-12-01.00-OG-U16-STD-2020-02-18-07-39-37.txt

    I find the bugreport really useful, including when looking for device management settings.


Running queries using adb.exe

When devices are enrolled via Device Owner (Android Enterprise) most system and preinstalled apps will be hidden, however there are occasions where systems apps are critical to business functions, e.g. Zebra datawedge, so bringing those back is necessary.

Fortunately, you can whitelist system apps with MEM Intune by following the instructions listed here:, however you may not know the app package name so having a way to look those up is necessary.

To list all apps installed on the device (hidden or not) run: adb shell pm list packages -s

Truncated example output:



















Use adb shell to interactively query

There may be situation where you will need to do some real-time queries and Google documents these here:

For example, I can investigate the battery details by running: adb shell dumpsys battery – with the output I can see the date the battery was manufactured, which is useful in determining if a battery needs to be replaced.

According to Zebra docs, “A battery is considered to be decommissioned if the Health percentage of the battery is less than or equal to Percent Decommission Threshold.” Looking at the highlighted values below, looks like my battery is still good to go.

Troubleshooting OEMConfig settings

If you’re interested in going deeper we can utilize the debug output (adb.exe bugreport c:\temp\ to look at memory usage, apps status, settings, etc. For example, I set the time on my Zebra device using OEMConfig settings, however if there was an issue, I (or support) could use these logs to troubleshoot settings.

The following is the setting I pulled from a very long list of settings in the debug file where my policy successfully applied. Again, if there was an issue, I would simply find the setting and verify if it is set or not.


_id:55 name:time_12_24 pkg:com.symbol.mxmf.csp.clock value:24 default:24 defaultSystemSet:true

Note: some Device OEM OEMConfig apps have policy/debug info builtin so you may not need to look at the logs, e.g. Samsung Knox Service Plugin.

Application troubleshooting

If you have an app that you’d like to test via Device Owner and Work Profile enrollments, using the Test DPC is helpful.

According to Google:
We provide the Test DPC app to help Android developers test their apps in an enterprise environment. Using Test DPC, you can set EMM policies or managed configuration values on a device—as if an organization managed the device using an EMM. Source

  • Connect the debugger and sideload the apps then install Test DPC to test app functionality.
  • Sideload app and see if it installs successfully
  • For app updates, the version code must be sequential and the signing cert must match

Google walks through how to provision devices using Test DPC here:

Wrapping up

Debugging devices isn’t something you may do every day, however it’s useful to know and if needed the option is available.  Additionally, the MEM Intune app with Android Enterprise Device Owner enrollments has a button to send logs to Microsoft support so you may not need to do any debugging.  However if there is systemic issue occurring across multiple devices, debugging is a good in-house path to go down.

Android Enterprise Dedicated device – matching a physical device to a device record in Intune

I work with organizations who have 100’s to 1000’s of managed devices in Intune.  When it comes to Android there may be various Android OEMs and OS versions organizations are managing and a variety of use cases for those devices.  With more organizations migrating to Android Enterprise they must choose an enrollment method based on the scenario.  With Android Enterprise there are several methods of enrollment, Dedicated, Work Only, and Personally-Enabled.  For more details on Android enrollment options please visit:

For digital signage, kiosks, barcode scanners, etc. those devices are typically enrolled as a “Dedicated” device where a single or multiple apps are the only apps accessible by the end user. In addition, dedicated devices do not have user affinity, meaning the device isn’t linked in an MDM to a specific user unless there some sort of tagging associated which identifies the user or location of the device.

Because there’s no user affinity assiated with dedicated devices, I’m often asked, “what’s the best method to identify an Android device enrolled as a dedicated device (e.g. kiosk) in the Intune admin portal with a physical device in hand?”

There’s a simple method of doing this and it’s identifying the device by serial number. Here’s how to do it without removing the battery:

1.  With the device turned on tap on the arrow key on the bottom left about 15 times to launch the options (btw, the screen with the app(s) you’re accessing is called the Microsoft Managed Home Screen). Depending on the app configuration for the managed home screen you may see “Logs” and/or “Exit Kiosk”.

2.  Select “Logs” and slide up on the Logs banner to expand

3.  Find the “deviceInfo” and tap the + until it expands

4.  Locate “serialNumber” and match it to the device serial number under “All devices” in the Intune admin portal. If you don’t see the “Serial Number” column select “Columns” at the top of the page and add “Serial Number” to the list.

Here’s a video showing the process in action:


In summary whether your organization manages 10 or even 1000’s of devices, having a simple method of identifying a physical device will save a lot of time during the process of troubleshooting.
