The Fastcall Mobile App requires certain device permissions to provide the full calling and notification experience. These permissions allow the app to operate correctly in the background, notify you of incoming calls, and provide access to essential features.
When you open the app for the first time, you’ll be prompted to grant the required permissions. Follow the prompts and select the recommended options to ensure the app functions as expected.

If camera access is denied, a warning notification will appear. Click Open Settings and enable Camera permission.
Notification Permission
