A sketchy new report [PDF] from analysts at KDB Daewoo Securities Research shared by OLED-Display.net (via BGR) claims to have full details on Apple's iPhone 6, but there are several issues with the claims that call the entire report into question.
According to the report, the iPhone 6 will be available in two sizes, one with a 4.7-4.8 inch display and a second at 5.5 inches. These displays are said to run at 1920x1080 (440 ppi) and 2272x1280 (510 ppi) respectively, using indium gallium zinc oxide (IGZO) technology rather than the low-temperature polysilicon (LTPS) technology used in current iPhones.
While the claimed display sizes are in line with circulating rumors, the claim of IGZO over LTPS raises some doubt given that LTPS offers better electron mobility and thus greater efficiency than IGZO. IGZO is starting to gain popularity in larger devices such as tablets due to technical limitations with creating LTPS displays at those sizes, but LTPS remains the preferred technology for many high-end smartphones. Still, it is possible that larger displays at higher pixel density for the iPhone 6 could spur Apple to change its display technology.
Other claims in the report include a bump in RAM to 2 GB alongside a new A8 chip, a new 128 GB storage option at the high end, and an upgraded 3.2-megapixel front camera. In line with a previous claim, the analysts predict that the rear camera will remain at 8 megapixels, although it could gain other improvements.
Another questionable claim of the report comes with regard to the device's operating system, with the analysts pegging the device as running iOS 7.2. Each new iPhone model has been accompanied by a major iOS update, and so the iPhone 6 would be expected to run iOS 8 at launch. iOS 8 has been observed in web logs and other sources, but there has been no evidence yet of Apple working on an iOS 7.2.
Finally, the report gives a fairly wide launch window of the second or third quarter of this year. iPhone launches have come at the tail end of the third quarter or even early in the fourth quarter over the past several years, with repeated rumors of Apple possibly returning to the mid-year launch window used for early models failing to come to fruition.
