Follow the below steps:

1. Remove the lockdown.

2. Open the phone dialer

3. Send the script "identify_activity"

3b. If the device prompts for a user action pending, allow MobiControl access to the device usage then go back to step 2.

4. Look in the device logs, you may have to make the device check back in to see it. It will give you the activity name for what is on the screen.

5. Add that activity to the lockdown. 

Hi Bruno, 

Depending on the version of Android that you are using Google may have changed the default telephone App to an ID that points to the devices's contacts, where they have now relocated the default dialer option.

Although the information provided by Allen is the best way to go about this, in previous versions, ie Android 7 and 8 it may be a littler bit harder to get the actual bundle ID using indentify_activity as a result of this change.  You may even have to enable the manually enable "usage data access" for the MobiControl Agent to even get a result in the logs. 

I used the activity recently so here is an example of the bundle ID that it has been changed to. 

com.samsung.android.contacts/com.android.dialer.DialtactsActivity

Hope this helps,

Regards

Thank you Allen and support for your help

When I click on the phone icon 

Activity is com.samsung.android.contacts/com.android.dialer.DialtactsActivity

I add it on lockdown, link works fine but icon displayed is different ( contact icon instead of phone icon)

Hi Bruno

I went through the same issues with the XCover 4 and the phone on lockdown so I feel your pain.

I got over the icon issue by uploading a phone icon in the Lockdown/Kiosk settings and assigning it to the app.

If you have done the same as me and forgot about messaging too the app name when you need it is  com.samsung.android.messaging :)

In the end we've scrapped lockdown and control all app access via Managed Google Play applications.  That's all users see from the Google Play app.  It was easier for us.

That is because the dialer is part of contacts. I've attached a logo i've used before and changed the lockdown to use the image instead of the Exe Icon. 

Thank you I change the logo in the kiosk and now it works fine, thank you everybody
