If in Firefox I click on a phone number then a window opens where I can select kdeconnect then my smartphone, then this launches the phone app in android. Good.
If in kaddressbook I click on a phone number, then this launches skype.
I would prefer that kdeconnect is launched. How to do that ? How to make kdeconnect as the default app for phone call in kaddressbook instead of skype ?
Did you try to configure this in the KAddressBook configuration or do you just ask here as your first action?
When you tried, then please tell what you tried so that not the people that want to help you have to walk that path in vain.
tWhen you did not try, why didn’n you?
