iPhone 8 will come with major re-design. This years iPhone 7 will look very similar to the iPhone 6S but next years model will be completely different and will come with an OLED display, plus a glass body, the display on the device is sais to be an edge to edge display.
Apple will also do away with the home button on the iPhone 8 and the handset will also come with wireless charging and there will apparently be no home button.
The handset will come with Apple’s Touch ID, although this will apparently be integrated into the handsets display as will the camera on the device.
These are all rumors at the moment, but it would make sense for Apple to give the handset some major upgrades in order to boost iPhone sales.
