Reports have surfaced that Apple's next flagship smartphone may be delayed by several weeks and will not launch in September like previous iPhone generations.

According to Brian White, an analyst from Drexel Hamilton, the delay is potentially down to difficulties with the device's 3D sensing technology, which is reportedly for the front and rear camera.

White revealed to CNBC: "First off, our smartphone contact believes the 3D sensing technology and OLED displays will only be offered with the 5.8-inch iPhone 8.

"However, our contact strongly believes the 5.8-inch iPhone will be delayed by several weeks due to challenges around the 3D sensing technology but still in time for the December holidays."

White also toys with the idea that Apple could keep with tradition and announce the iPhone 8 in September but instead only accept pre-orders at that stage.

It is believed the 3D sensing technology is for facial recognition, as well as Tim Cook's ambitions in including augmented reality in the latest model.
