The iPhone 8 is expected to release later this year with a 5.8″ display. It is also expected to adopt the thinner bezel design of the Galaxy S8 and LG G6. This means the device will feature the larger display while keeping a smaller overall footprint. The leaked dimensions of the device are 143.59×70.94×7.57mm which is only slightly bigger than the iPhone 7 at 138.3×67.1×7.1mm. This is even smaller than the Galaxy S8 which also features a 5.8″ display. The edge to edge display is really making quite the difference in size.
One other detail worth noting is that the iPhone 8 renders do not show a fingerprint scanner on the back. Apple may or may not be able to embed the fingerprint scanner under the front glass with this device. This is something Samsung was working on with the Galaxy S8, but wasn’t able to finish before the release of the phone.
