OppoMart, an online retailer site from China, is known for listing unreleased smartphones and accessories. The Chinese retailer has listed iPhone 7 and iPhone 7 Plus cases three months before the expected release of the upcoming Apple iPhone 7 series smartphones.

According to Gizmo China, the listing for iPhone 7 Plus case on the Chinese retailer has revealed that the phablet will be coming with dual camera system. However, the iPhone 7 case suggests that the smartphone will continue to sport a single camera.

It is interesting to note that OppoMart has made the iPhone 7 Plus case available for preorders with a price tag of $9.99 and its shipping date is mentioned as June end. Even though the iPhone 7 Plus seems to sport a dual camera system, its overall design seems to resemble iPhone 6S Plus.

In January, Ming-Chi Kuo, an analyst from KGI Securities, had revealed that the dual camera system of iPhone 7 Plus would be featuring two 12-megapixel cameras manufactured by Sony. One of the camera lenses is expected to feature wider aperture and the other one would carry support for optical image stabilization. Moreover, the acquisition of LinX, an Israel-based firm, will allow the camera to shoot DSLR quality images.

Rumors have it that the Apple iPhone 7 Plus phablet will continue to sport 5.5-inch screen with full HD resolution support. It will be powered by the next generation Apple A10 chipset. It is expected to be supported by 3 GB of RAM.

Fresh speculations suggest that the iPhone 7 and iPhone 7 Plus smartphones will be coming in three storage versions of 32 GB, 128 GB and 256 GB. It is also rumored to house a battery of 3,100 mAh capacity. Apple is speculated to announce and release iPhone 7 and iPhone 7 Plus in September this year.
