Hello

This also worked for me.

Launch://com.android.contacts/com.android.dialer.DialtactsActivity

Hello simon,

I think it's : Launch://com.android.dialer

try and tell us

Hello Simon,

you can also use:  Launch://com.samsung.android.incallui  
or
Launch://com.android.phone

try it :)

Thanks for your replies to this point.

Only using Launch://com.android.phone makes the phone icon appear in the lockdown.

But when clicking onto it, there is an error message "Package not found".

I don't know how to resolve this issue.

perhaps open the device on remote and look into the application manager tool

search after the app phone for identity the app who is used

Hi, just try this:

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

I searched for that, a few days ago and the support could help me with that for my Samsung Galaxy A5 2017

The best way to do this is to identify the bundle_id from the installed applications, and have the same in the lockdown profile. The bundle_id of the installed app should match with the one in the lockdown profile.

Thanks everybody!

Launch://com.android.contacts/com.android.dialer.DialtactsActivity worked for me! :)
