It was speculated before the release of Apple's flagship smartphone iPhone 7 that the Cupertino giant could face a supply shortage with some suppliers not being able to fix low yield rates of their components, and analyst at Yuanta Investment Consulting Jeff Pu even cut his forecasts for iPhone production by few millions units citing technical issues the device could face. Now, supply issue has literally hit Singapore, leaving many fans and consumers disappointed.

Singapore's major carriers like M1, Singtel, and StarHub have admitted that they couldn't deliver iPhone 7 handsets to the customers, who have already pre-ordered, owing to Apple's inability to supply some variants of the device.

"iPhone 7 Jet Black and all variants of the iPhone 7 Plus are currently out of stock," wrote M1 on its Facebook page, a day before the scheduled release date. Singtel has announced that the iPhone 7 and iPhone 7 Plus won't be available on Friday after Apple delayed shipment. StarHub also said that the iPhone 7 256GB in Jet Black and Silver won't be available as scheduled due to supply issue.

Major wireless carriers were supposed to make the iPhone 7 and iPhone 7 Plus available to their customers in Singapore on Friday.

Apple's iPhone 7 sports a 4.7-inch (diagonal) LED‑backlit widescreen with Retina HD and 1,334x750p resolution (326 ppi pixel density), and features a fingerprint-resistant. Under the hood, it has a 64-bit A10 Fusion chip with M10 motion coprocessor, an Apple iOS v10, a 32GB/128GB/256GB internal memory, and a 2GB RAM. It also has a 12MP main camera with f/1.8 aperture, digital zoon (up to 5x), Optical image Stabilisation, six-element lens, and Quad-LED True Tone flash, a 7MP front-snapper with ƒ/2.2 aperture and auto image stabilisation, and a 1,960mAh battery.

On the other hand, the iPhone 7 Plus has a 5.5-inch (diagonal) LED‑backlit widescreen with Retina HD and 1,080x1920p resolution (401 ppi pixel density). It is powered by a 64-bit A10 Fusion chip with M10 motion coprocessor, runs Apple iOS v10, packs a 32GB/128GB/256GB storage and 3GB RAM, and houses a 2,900mAh battery.

The device has a dual 12MP main camera (ƒ/1.8 aperture) with wide-angle field of view + telephoto camera (ƒ/1.9 aperture), Optical zoom at 2x, digital zoom up to 10x, Optical image Stabilisation, six-element lens and Quad-LED True Tone flash, and a 7MP front-snapper with ƒ/2.2 aperture.
