Given that the overall design of the iPhone hasn't changed much since the release of the iPhone 6 back in 2014, there's a lot of pressure on Apple to deliver a home run when the company launches the iPhone 8 later next year.
Though next year's iPhone would ordinarily be called the iPhone 7s, it's widely believed that Apple's next-gen iPhone will represent such a compelling upgrade that Apple will opt to call it the iPhone 8 instead.
Now, as for what Apple has in store for us with the iPhone 8, the company's plans are beginning to crystalize slowly but surely. According to analyst Ming-Chi Kuo (via Apple Insider), Apple next year will introduce three distinct iPhone models.
Of course, we can expect to see a 4.7-in. iPhone 8 and a 5.5-in. iPhone 8 Plus. But the real star of Apple's upcoming iPhone lineup will be a premium version of the Plus that will feature an edgeless display along with a curved OLED panel. In contrast, Apple's non-premium iPhone models will continue to employ LCD panels. At this point, it remains unclear if every new iPhone model will feature a redesigned form factor or if Apple is reserving this special treatment for its top-of-the-line iPhone exclusively.
As we've highlighted previously, a number of iPhone 8 rumors point to Apple's next-gen device sporting an edge-to-edge display with all of the accompanying sensors being embedded beneath the display itself. While some rumors have hinted that the home button might be integrated underneath the display, more recent reports suggest that the iPhone 8 will mostly be edgeless, save for a small bezel with the home button located towards the bottom.
Also of note are reports that Apple's iPhone 8 models will employ a glass casing strengthened by a stainless steel frame. Apple, of course, has used glass casings on the iPhone before, but we haven't seen it since the iPhone 4s was released back in 2011.
As for other iPhone 8 rumors that have been making the rounds this past week, another note from Ming-Chi Kuo relays that dual cameras on Apple's 5.5-in. iPhone 8 Plus and the premium iPhone 8 model will both feature dual optical image stabilization. As it stands now, only the wide-angle lens on the iPhone 7 Plus supports dual optical image stabilization.
