Hi,
we have a problem with a lockdown at our Samsung Android 10 devices.
I want to open the phone app, so the employees are able to call numbers, which is working fine.
The only thing that doesn't work is dialing numbers. As soon I want to dial and press the "dial" button the number disappears and that's it.
I don't see any error in the configuration so far, see attached screenshots.



Does anyone have any idea about this issue?
Thanks in advance,
