The Samsung Galaxy S4 Mini has appeared on the company's official website, Digital Spy said.

The as-yet unannounced device briefly appeared on Samsung's Content & Services web page before being removed, reports Trusted Reviews.

The phone's thumbnail seems to confirm the authenticity of S4 Mini images that were leaked in March.

The shrunken handset is said to be powered by a 1.66GHz dual-core processor and run Android 4.2.2 Jelly Bean out of the box.

The Galaxy S4 Mini will allegedly feature a 4.3-inch Super AMOLED display, with a resolution of 540x960 pixels and a pixel-per-inch count of 256ppi, making it larger than the Apple iPhone 5.

The device is expected to launch alongside a water and dust-proof edition dubbed the Galaxy S4 Activ. Both handsets are expected to release in mid-July.

A Galaxy S4 Zoom is also said to be in development, offering a more powerful 16-megapixel camera than the standard 13-megapixel snapper.
