Ok those are the specs we know so far for release April 19
There are multiple versions of each.
Im after the Mi6 6GB model.
Main Specs
OS Android OS, v7.1.1 (Nougat) Chipset Qualcomm MSM8998 Snapdragon 835 CPU Octa-core (4x2.45 GHz Kryo & 4x1.9 GHz Kryo) GPU Adreno 540, IMX400 Sony 19MP Sensor (4 axis stab and I believe OIS). Dual SIM
So far the testing I have seen it is running faster than the Galaxy S8, so for me the specs are there all I need to know is the glass in front of that IMX400. 240fps 720p, 120fps 1080p, SWEET !
