The latest iPhone 6 concept image has featured a 4.7-inch screen display and 4K capture.

Jermain Smit, a smartphone concept designer, imagined the next iPhone to have a bigger screen display that is 4.7-inches. The screen has full HD resolution, according to Concept-Phones.

At the back, the iPhone 6 concept packs a 10 megapixel back camera with 4K video recording. There is a dual LED flash at the back. Under the hood, the latest render packs 2 GB RAM on board, 32 GB or 64 GB of storage, iOS 7.2 and a 3.2 MP front camera and 2300 mAh battery.

Concept-Phones added the handset will be powered by A8 64 bit quadcore chipset. Also, there was a new port at the bottom and the touch ID home button was improved. Overall, the smartphone is wider than usual but it is thinner than its predecessors.

Taiwanese media Economic Daily News reported two iPhone 6 variants with bigger screen display are underway. One of the new iPhone models was speculated to be Apple's take on the phablet category.

The report said Apple will launch a 4.7-inch iPhone 6 and phablet with 5.6-inch screen panel. The phablet model was an experimental smartphone, apparently, to test the waters. But the report did not disclose the official name of the two handsets and the official release date.

Meanwhile, A8 processor, iOS 8 and fingerprint sensor were some of the features that will most likely arrive in the next iPhone. Some Apple patents such as curved or flexible screen embedded with liquidmetal material, sapphire glass screen display, improved Siri and gestures control may come to the next Apple handset.

Apple still has not leaked the real iPhone 6 release date. But some rumors claimed iPhone 6 will be launched in June at the Worldwide Developers' Conference alongside a new operating system. Other reports noted Apple will wait for a year and release the device in September.
