As previously reported, Apple’s iPhone 7 and iPhone 7 Plus are suspected to debut in five different color options — Space Gray, Gold, Rose Gold, Silver and the newest addition to the mix, Glossy Black. Interestingly, a new leak has surfaced and it is hinting at two black options that the Cupertino giant could have tested for the prototypes of its upcoming iPhones.

On Sunday, Apple Insider spotted the latest leak on Twitter, and it’s from regular leakster The Malignant (@the_malignant) who got photos of prototype stickers for the new black variants of the latest iPhones. 

Based on the labels of the stickers, one is for a Matte Dark Black iPhone model that sports 128GB of onboard storage, while the other is for a Piano Black model that comes with 256GB of internal memory. 

Since both stickers contain the model code D10, they are said to be stickers for the new iPhone 7, and in the thread that followed after the tweet was posted, The Malignant claimed that it has been “confirmed” that Apple has testing machines for both color variants. However, the leakster admitted that the Piano Black model could be a fingerprint magnet. 

It isn’t clear if the Glossy Black iPhone 7 that was outed in late August is the Piano Black model this new leak is suggesting and if the Matte Dark Black iPhone 7 is the Space Gray color option, which has been darkened per previous rumors. 

The Malignant previously leaked that Apple came up with three prototypes for its new iterations, namely: the D10, D11 and D12. Apple Insider pointed out that these three were for the standard iPhone, the Plus model and the now defunct iPhone Pro variant. 

The new leak comes a day after KGI Securities analyst Ming-Chi Kuo dropped a detailed list of the predicted specs and features of the Samsung Galaxy S7 and Galaxy Note 7 rivals when they officially launch on Wednesday. 

MacRumors has learned from Kuo that the iPhone 7 and iPhone 7 Plus will house the A10 chip and will come with improved LED flash for superb quality photos. Furthermore, the analyst stated that the new iPhones will have a new audio amplifier instead of a second speaker and that only the larger variant is going to come with the dual-lens camera system.

Apple fans will know more about the interesting iPhone 6s and iPhone 6s Plus successors when the Cupertino giant officially unveils them to the public on Sept. 7.
