Apple's upcoming flagship phone 'iPhone 8' is currently under prototype testing with various LCD and OLED screens. The OLED version of iPhone 8 will be dubbed as 'iPhone Edition', since it will be marketed as the top-of-the-line model like the Apple Watch Edition.

The flagship handset is expected to hit the store shelves following an announcement in September and sell upwards of $1,000, which is in line with earlier rumours. Several of the iPhone 8 features are still not finalised with the exception of wireless charging, OLED display technology and dual cameras, according to Japanese blog Mac Otakara.

Earlier, KGI Securitites analyst Ming-Chi Kuo predicted iPhone 8 would come with flexible OLED display and pressure-sensitive 3D Touch on a 5.8in display, wherein 5.1in would be the usable screen space while the unused bottom portion of the display provides access to virtual buttons for navigation.

The report further adds that the Cupertino Company is testing multiple prototypes using LCD and OLED versions of the screen, besides testing units with and without Home buttons. Furthermore, Apple is reportedly validating the best material for mass production of chassis by experimenting with glass, aluminium and white ceramic.

Given Apple's commitment to bring out the best model as its flagship device, we could only expect the iPhone 8 to truly stamp its class and authority as a special edition model mirroring the likes of Apple Watch Edition.
