Apple has received a huge number of orders for the jet black version of the iPhone 7, and the company is reportedly facing difficulties meeting them soon due to the complexity of manufacturing this particular variant of the phone - resulting in a global shortage.

The jet black iPhone 7 was one of the most in-demand versions of the smartphone after it was released earlier this year. However, the jet black iPhone is only available as the 128GB and 256GB versions of both the iPhone 7 and the iPhone 7 Plus.

The jet black version of the iPhone 7 is quite popular despite the fact that it prone to getting covered with fingerprints and could get scratches and scuffed edges.

According to KGI Securities analyst Ming-Chi Kuo, the Jet black variant of the iPhone 7 is experiencing a flat casing production yield rate of 60-70 percent. This means that up to 40 percent of the phones, or the casing for them, produced do not meet Apple's quality standards for the iPhone 7 and 7 Plus.

Add to the fact that this time the iPhone was released in 28 countries, compared to only 12 last year. This clearly explains the shortage of the device with reportedly over 30 percent of the orders globally being for the jet black iPhone 7.

Another factor that played in Apple's favor is the latest Galaxy Note 7 fiasco which has driven demand higher for the iPhone 7 and 7 Plus. In the UK, Apple's latest devices were only available for customers who pre-ordered them. No devices were sold to walk in customers. The in-store availability of the jet black iPhone 7 is expected to improve in October.
