Photos of the rumoured Samsung Galaxy S4 Zoom have leaked online, Digital Spy said.

The as-yet unconfirmed device was shown on Sam Mobile, which claimed that it will be officially unveiled at a Samsung event in London later in June.

It is reported that the device will be able to make calls and take photos using a 16 megapixel camera sensor with optical zoom.

The image appears to show a shutter button, as well as volume controls that could also act as zoom buttons.

Zoom would be Samsung's first cameraphone based on Android and strongly resembles the existing Galaxy S4 line.

The report also claims that the Zoom has a 4.3" qHD sAMOLED display and a 1.6GHz dual-core processor. Bluetooth, Wi-Fi and GPS capabilities are said to be included, as well as 8GB of memory and the ability to add additional space with a micro SD card.

Samsung will unveil new products at its Premiere 2013 Galaxy & Ativ event in London on June 20.
