Galaxy S8 comes in at 5.8-inches with an extra-tall 18.5:9 aspect ratio display. The 3000mAh battery is actually 100mAh smaller than the Galaxy S7 edge, while the processor is backed up by 4GB of RAM, an increase to 64GB of storage, and of course a microSD card slot. The rear camera is unchanged in terms of its 12MP sensor and f/1.7 lens, but has improved processing thanks to new software and a new ISP (image signal processor).
