One unedited version of iPhone 5s appeared online through some photos posted on the Twitter account @DongleBookPro. The one depicted in the photos is probably a prototype built by Apple before the product launch in a black color never released to the public .

iPhone 5S was launched at September 2013, introducing for the first time in the Apple smartphone line the Touch ID fingerprint sensor, a 64 – bit and a dual LED True Tone flash. The smartphone used a single photo module with five-element f / 2.2 optics, a larger sensor for the camera than its predecessor, and slow-motion mode for video recording (at resolution 720 pe 120 fps).

Lo smartphone was proposed only in the variants Space Gray, Silver and Gold , colors appeared for the first time in the line -up, while iPhone 5 – which enjoyed an extremely similar design compared to its successor – was proposed in White and Silver and Black and Slate . According to the source, however, Apple has never thought of reviving the Black and Slate also on the iPhone 5s , but he made the first prototypes with the old color to camouflage them during development.

It is curious to note that the iPhone 5s in the photo was made in December 2012, three months after its predecessor’s launch and nine months before its commercial debut. Together with the disclosure of the first rumors about the new models, this news helps to understand how long the development cycle of the new products is before they are released to the public. From iPhone 5s onwards Space Gray has supplanted Black and State on almost all subsequent iPhones: the only ones not to propose this color were in fact iPhone 7, iPhone 11 and iPhone 12 (is 12 Pro).

Black and State was instead a fleeting presence among the colors of the iPhone, despite the beauty of the finish and elegance perceived by sight and touch. Popular on iPhone 5, fifth generation iPad mini and fifth generation iPod touch, the finish was immediately revealed extremely delicate and prone to show signs of wear of all kinds, including including scratches and dents, with evident loss of the surface paint . Perhaps for this reason Apple has decided to eliminate it from the iPhones immediately after the first implementation on the iPhone 5.
