Frequently Asked Questions

How can we do Bulk Enrolment?

This is a feature of Enterprise version. There is an “Import plugin”, it will help you to upload multiple devices of the same configuration at once.

  1. Prepare an Excel sheet with at least one column (device identifier). There could be up to 3 columns (device ID, IMEI and mobile phone number).
If you cannot enter the number because they appear as floating point numbers, change the cell format to “Text”.
  1. Select Functions - Import devices. If you do not see this item, make sure the plugin is turned on (Settings - Plugins).
  2. Upload your Excel file, select the configuration and setup the columns.
  3. Click “Import”, make sure everything is correct, and click “Import” again.
    However there's no "Zero touch enrollment" so you still need to follow the enrollment flow with scanning a QR code on each device.

How to exit the kiosk mode?

Exit the kiosk mode is a bit tricky. You need to tap 4 times on the top left corner of the screen (there is an almost transparent key icon visible when your kiosk is dark).After that, type the admin password. The kiosk will be unlocked and you’ll enter the admin panel where you can open the device settings and do other admin actions.

Sometimes you will see just a black screen after tapping the screen corner. In that case, click the Home button.

Alternative way is to switch the configuration from the Kiosk mode to the Launcher mode (this is done in the “MDM Settings” tab of the configuration details) and then tap and hold the key icon.

Cannot upgrade the application: signatures do not match

This error is raised when the signatures of the previous and new versions of the application are different.

Please read more about the application signatures here: https://developer.android.com/studio/publish/app-signing

There are two possible solutions of this issue.

  1. Sign the app with the correct keys

  2. Force uninstalling the previous version and install a new one (all app data will be lost!).

If you care about the app data and would still like to update the application without removing the previous version, you need to address this issue to your development team.

There are two general reasons why the app could be signed by wrong keys:

  1. The developer has released a debug version by mistake, because the debug version is by default signed by debug keys which are different from release keys.

  2. The development team has been changed and the keys are lost (that’s the worst and unrecoverable case!)

Please ell the following to the client’s development team. The signature of the new version is different from the previous one, and I cannot update. Please could you fix the issue by signing the new version by the same keys as the previous one.

After you get a correct version, just upload the new version in the “Applications” tab. When the control panel asks you whether you’d like to add a new application or a new version, answer “New version”. The wrong version will be replaced by the right one.
