Samsung is one of mist favorite smartphone company . they are too progressive. They provide the new model of smartphone with I think very month and generally every phone has some unique feature. Samsung z1 is that one with unique feature and had the different os ( operating system and has super AMOLeD . GUi os samsung z1 is too much worst.
I persanally hate samsung z1 only beacuse of operating system and thair features. Tizen os doesent support android apps. So you cannot run abdroyd aoos on samsung z1 and you don’t have access to goole products.
I suggest you to don’t buy it
