A free app for Android, by Silver Land Farm.

Photo Caller Full Screen is a very useful application for those people who are looking for a way to customize their phone’s calling screen. It allows you to choose between a number of themes, including the default theme, as well as themes that you can create yourself. It also includes different options for incoming and outgoing calls, so you can choose between the default option, which shows a simple screen with a button to start and stop calls, and the Full Screen option, which shows a full-screen photo of the caller.

The application also includes a contact list, so you can choose to have the contact names displayed on the screen. It allows you to add a ringtone for each contact, as well as a background image. You can choose between the default ringtone, as well as the option to add your own ringtone.
