iPhone users anticipate Apple's upcoming smartphone models. Rumors have arisen that the next release will have an enhanced camera that matches a DSLR.

The iPhone 6 and iPhone 6 Plus recent release is speculated to be followed by an early launch of its successor iPhone 7, International Business Times reported.

Several reports claimed that Apple's upcoming device has superior features compared to its older versions. Rumors have suggested sapphire glass screen, chasis made of liquidmetal and a camera with two lens that takes high quality pictures.

Although many iPhone users demand for a smaller screen size, iPhone 7 has been expected to have a bigger screen than iPhone 6 Plus, according to iPhone7Update.com. The screen size is supposed to improve the viewing experience of the users, displaying "crisper" pictures and "clearer" videos.

The anticipated device is also rumored to have DSLR features, enhancing the quality of the pictures taken using the phone. There's also a chance that the camera will feature a lens-swapping characteristic since earlier this year, Apple has submitted a patent for swappable lenses, according to TechRadar. The device is also rumored to have a 14-megapixel front panel camera.

There are also rumors of a built-in projector on the iPhone. It wouldn't be the first though, because Samsung Galaxy Beam was released with the same feature.

Furthermore, the possibility of a 3D display has also emerged, according to Economic Daily News. The report claimed that Apple supply chain partner TPK has been working on a project that involves "naked eye 3D screen," which doesn't require glasses to experience 3D display.

Regarding its cost, iPhone 7 is expected to be more expensive than all of its predecessors. The price is speculated to range from $649 to $849, according to iPhone7Update.com.

Apple has been planning to release a new product every six months to improve its competition against another smartphone giant, Samsung Electronics, according to Stabley Times. Samsung has released the famed Galaxy series and Apple aims to develop more devices to gain more sales.

Reports claimed that the release date for 2015 involves iPhone 6S and iPhone 7. Apple is supposedly releasing iPhone 6S during spring time while iPhone 7 will be launched on September.
