The Google Pixel 7 duo is seen on video, giving a close examination of the size difference between the devices

The Pixel 7 series phones were already teased during the Google I/O conference earlier this year. In terms of design and internal hardware, the Pixel 7 and its Pro version might be our first real look at these devices.

An Unbox Therapy video purports to show prototype units of the Pixel 7 and 7 Pro with black trims. A metallic finish adorns the camera island this time around, which contrasts sharply with the subdued black glass strip on the Pixel 6 duo. 

The rear glass panel also appears to have rounded corners, and the corners of the front glass panel appear to be rounded as well. Powered by the next-generation Tensor chip, the Pixel 7 Pro prototype has 12GB RAM and 256GB storage. 

With 8GB of RAM and 128GB of onboard storage, the smaller Pixel 7 comes with a lot fewer features. As soon as the phones get an official release in October, more trims with different memory configurations will also be available.

The two phones have a few notable aesthetic differences. The Pixel 7 Pro has a polished metallic frame, while the vanilla model has a matte finish. In comparison to the Pixel 6, the Pixel 7 has a noticeable size difference.

The Pixel 7 is noticeably smaller than its predecessor and has narrower bezels. The Pixel 6 is also narrower and lighter by about 10 grams. Those who prefer compact phones will be relieved, as the Pixel 6 was quite chunky and larger than the Pixel 5.

When it comes to the Pixel 7 Pro, its display curves are less pronounced than those on the Pixel 6 Pro. In addition, Google appears to have slightly trimmed the vertical bezels on the Pixel 7 Pro, but the overall size appears almost identical to its predecessor.

 The Pixel 7 Pro has a slightly trimmed side profile, but it is wider than its predecessor, the Pixel 7.   This appears to be a prototype unit, so we cannot see the software since the devices are not bootable.

 Despite this, both phones will run Android 13, which is not much of an aesthetic improvement over Android 12 but does bring a few useful tweaks. Pixel 7 Pro will reportedly sport a 6.8-inch OLED panel, while Pixel 7 sticks with a 6.2-inch panel.

As far as imaging hardware is concerned, not much will change. It is rumored that the Pixel 7 will feature a 50-megapixel main camera and a 12MP wide-angle lens.

A 48MP telephoto camera is expected to be added to the Pixel 7 Pro, along with a folded-lens periscope zoom system like the Galaxy S22 Ultra. There are three colors shown in Google's official teasers: black, white, and a gorgeous grayish-green trim with a bronze camera strip.

The Pixel 7 comes in a range of color options, including lemony, all-black, and all-white. If the Pixel 6 duo is any indication, the Pixel 7 pair will have an aggressive price tag, at least in the U.S. market.
