Next-generation iPhones likely to focus on internal improvements.
Video Compares 5.5-Inch iPhone 6 Model to Samsung Galaxy Note 3
However, YouTube channel TechSmartt (via AppleInsider) has acquired a dummy of the 5.5-inch iPhone 6 and compared it to the Samsung Galaxy Note 3, offering a look at Apple's rumored "phablet" against its main competition.
When compared to the 5.7-inch Note 3, the 5.5-inch iPhone 6 is slightly taller. This correlates with an earlier size comparison that found the 4.7-inch iPhone 6 was the same height or taller than leading Android smartphones that had slightly larger screens.
If believed, these dummy models signal that the 5.5-inch iPhone 6 could be taller than the Note 3's height of 151.2mm. The extra height is largely due to a carryover of design decisions from previous iPhone models, which include identically sized top and bottom bezels. These bezels contain the FaceTime camera, the Touch ID Home button and numerous sensors.
