You need to do this for each contact. The process initially may seem weird but works well.

1. Open a contact
2. Click Edit
3. Click Edit below the Picture
4. Select Edit Photo
5. Move the Circle around the image (just move randomly, a bit)
6. Choose Photo
7. Click Done
8. Next time when you receive call from this contact, it will be full screen!!!!
