Abstract: A passthrough case for a smart phone which provides a supplemental screen and controls for operating a camera of the smart phone. The passthrough case for a smart phone generally includes a cover for retaining a smart phone. The cover includes a phone receiving portion in which the smart phone is frictionally retained and which allows the display and controls of the smart phone to be fully accessible. A male connector extending from the cover interfaces with the data port of the smart phone to passthrough camera functionality to the cover. The user of the present invention may utilize a screen and controls on the cover to control camera functionality of the smart phone, thus significantly easing the process of taking self-portraits.
