This is usually because the notification configuration prevents incoming call notifications from being displayed. Here are several solutions.
1. Use the in-call UI provided by the system
Uncheck option DW Contacts → Settings → In call widget → Full screen mode.
If you use Android 13 and later, you cannot set DW Contacts as the default phone application using this method.
2. Correct notification configuration

Setup steps
- Find DW Contacts in the Application manager and open the notification options.
- Enable Incoming call notifications and its Pop on screen option.
- If the Allow full screen notifications option is included at the bottom of the notification list, it also needs to be turned on. Some phones also include an Allow background pop-ups option which should also be turned on.
- Restart the phone.
If the options cannot be modified, you may need to unset DW Contact as the default phone program first.
3. Use another app as your default phone program
- Unset DW Contacts as the default phone program
- The next time you launch DW Contacts if it requests to be set as the default phone program select Cancel in the “Default Phone Program Selection Dialog”. Then click Next.
