I have checked with the seller it definitely supports band 20. Not many reviews or info out there on this one apart from some videos on youtube but not any in English. However this phone looks great. Also support OTA updates - seller confirmed.
Curved edge glass just like the iPhone. Also supports micro SD up to 128gb.
