Apple's tenth-anniversary phone will feature a water drop design in homage to original iPhone introduced by the company a decade ago. Apple iPhone 8 will embody the back side design with curved emphasis according to sources.

According to ET, Apple adopted a 3D glass material on the back case of iPhone 8. This 3D glass case makes curves around the edges that are more gentle and rounded than the existing metal case edges. Apple iPhone 8 will be the first to adopt OLED display but not like Samsung Galaxy S7 Edge.

Many analysts have predicted that Apple iPhone 8 will adopt the front 2.5D cover glass. The display ratio is said to be larger than that of previous iPhones. Apple used a flat, rounded design from the initial iPhone to iPhone 3GS model in 2007. The company's tenth anniversary phone would feature a 5.8-inch display according to rumors.

From iPhone 4 to iPhone 7, Apple has used less curved, flat back design but this time, one the tenth anniversary, it will refresh the memory of first iPhone. As written in MacRumors, Apple used a curved aluminum and plastic design for the first iPhone and only plastic for the iPhone 3G. Apple iPhone 8 will have the same shape but will use all glass instead of plastic.

Some rumors suggest that Apple iPhone 8 will feature an edge-to-edge display with no side bezels. Also, Touch ID and fingerprint sensor will be built directly into the display. That means that traditional Home button will not be there on Apple iPhone 8. The phone will also support wireless charging feature.

Apple iPhone 8 is also rumored to add features like facial recognition. In dual-lens camera, both the lenses are expected to feature Optical Image Stabilisation. This year, Apple will launch three iPhones instead of two, where two will be traditional iPhone upgrades and one will be the company's tenth anniversary phone.
