It's too early to talk about any product that is likely to come out in a year or two. With Apple, however, any iPhone news is huge. In the case of the iPhone 9, the future flagship smartphone is indeed huge in more ways than one.
The reason why some are already talking about the iPhone 9 is due to its supposed size. "The Bell" leaked a story that Apple and Samsung are already working on a couple of OLED display, one measuring 5.28 inches and the other 6.46 inches. According to the report, the two rival companies have already put on paper their new partnership in which the Korean conglomerate will continue supplying Apple with OLED displays. The non-disclosure agreement included general conditions which included the aforementioned screen sizes.
MacRumors mentioned that Apple has 4.7-inch and 5.5-inch display in its current crop of iPhones. The highly awaited iPhone 8 is rumored to be coming with a 5.8-inch OLED display. The iPhone 7 and iPhone 7 Plus, meanwhile, will reportedly sport 4.7- and 5.5-inch screens. The report also mentioned that Samsung will likely ship "more than double at 180 million units" of the OLED displays. GSMArena noted that the figure dwarfs Apple's supposed order from Samsung of 80 million OLED displays for the iPhone 8.
Many may recall news from a while back that Samsung is investing a total amount of $9 billion in OLED technology. The investment is supposedly in accordance with the Korean company's deal with Apple regarding the production of OLED screens for its bitter rival. Apple is finally moving away from LCD screens and shifting to OLED.
Beside the huge screens, nothing else is known or at least rumored about the iPhone 9. With the huge disparity between now and the time that the iPhone 9 is expected, this piece of news should not be taken seriously. At least, not yet. It is wise to wait until after the iPhone 8 has been launched as more iPhone 9 rumors will start trickling in after that momentous event.
