[Update]

Long considered a reliable leak source, @evleaks tweeted the new renderings early Tuesday with his own watermark on the images.

One image features the proposed Galaxy S4 contrasted with a number of the phone’s predecessors, including the Galaxy S3, while the other image suggests that the phone includes a Super Amoled Full HD touch-screen display and a 13-megapixel, 4128 x 3096 pixels, autofocus, LED flash camera -- two of the most prominent rumors surrounding the S4.

Several tech sites have shared up the mock-ups, noting that they closely resemble many of the specs rumored for the phone, including a wide screen, front-facing camera and the absence of any home buttons.

The mock-ups keep in step with the suggestions of a 4.99-inch screen, a front-facing camera to accompany the 13-megapixel main camera and the implementation of “eye scroll” technology, making the Galaxy S4 significantly more hands-free.

After Twitter mumblings that un-watermarked versions of the mock-up were also circling the Web, Android Authority contacted Expansys via Twitter, and the company stated that the renderings belonged to them.

Specializing in the sale of unlocked phones, the online retailer has the same images at its placeholder website for the Galaxy S4 and said that @evleaks added his own watermark without permission.

The initial tweet about the renderings has since been deleted from @evleaks Twitter page.
