The UMIDIGI Crystal was first made available for purchase in July 2017. It offers a 5.5” 1080P IPS LCD display, resulting in a pixel density of ~401 PPI. Processing power is supplied by a MediaTek MT6737T SoC, which utilises a 1.5 GHz quad-core CPU, a Mali-T720MP2 GPU and 2 GB of system RAM. The 16 GB of internal storage is expandable, thanks to the dedicated microSD card slot. The primary camera is capable of capturing images at 13 MP, the secondary at 5 MP. The whole 180g package is powered by a non-removable 3000mAh battery.
