UMIDIGI are apparently still commited to delivering exactly one small piece of information a day about their upcoming UMIDIGI Z1 flagship. Not sure how much is such secrecy beneficial and the new information also sometimes slightly contradict the previous one, just like today.
According to an official statement of UMIDIGI the display types for the Z1 versions will be actually quite different. The standard Z1 will get just the ordinary LCD, while the Z1 Pro will be sporting the originally announced AMOLED screen. Dual camera design and USB Type-C port are untouched and should be present in both of the variants of the phone.
So this can be one of the factors explaining the disproportionate projected price of the UMIDIGI Z1 Pro and have to wait, if there is more coming to be cut or changed. Brace for some surprises in the next days, hopefully not of the similar kind. In the meantime you can still participate in subscribing and giveaway event on their official website.
