The 928 is rumored to have a both and xenon and an LED flash on the back to ensure you pictures have the required lighting conditions.
Instead of an LCD screen (as in the 920), the 928 will feature a 4.5-inch OLED screen. The other specs of the phone are expected to be the same with 1GB of RAM, a 1.5GHz dual-core processor and 32GB of storage.
Moving on the physical side of the device the 928 is also expected to be slightly thinner, “measuring 10.2mm at its thinnest point and 11.2mm at its thickest, with a slightly curved back” – The Verge.
