The iPhone 7 is just a month old, and rumours of what Apple is planning for its ten-year iPhone anniversary next year is already cropping up. A fresh report hints that the iPhone 8 will sport an all-glass back, and come in three variants instead of two. Furthermore, there is another report claims the three-variant rumour is untrue. A report from Nikkei Asian Review citing anonymous people familiar with the matter claims that the Apple iPhone next year will ditch the metal casing to sport an all glass casing instead. Furthermore, there will be another size variant added to the mix, and the iPhone 8 will be made available in 4.7-inch, 5-inch, and 5.5-inch sizes. “Apple has tentatively decided that all the 5.5-inch, 5-inch and 4.7-inch models will have glass backs, departing from metal casings adopted by current iPhones, and Biel and Lens are likely to be providing all the glass backs for the new iPhones next year,” the source told the publication.The report adds that one of the variants will sport an-edge-to-edge OLED display with little to no bezel on the top and bottom. The other two sizes will continue to sport LCD displays. In the meanwhile, a separate source with an accurate Apple leak record has told Apple Insider that the company has no plans to launch a third 5-inch variant. The company will stick to tradition with respect to size, and only the 4.7-inch and 5.5-inch will launch next year. The glass back rumour has cropped online earlier as well, and this latest report further cements its arrival. Apparently, the next year’s iPhone will see major changes, and apart from the above mentioned rumours, it is also expected to get rid of the Home button completely, integrating it with the display.
