Samsung Z2 is a mobile phone which does not have much uses.There is a good feature that it is 4g mobile phone in just 4500rs but having so many disadvantages like it’s ram is too less-1gb and it’s look is also not good.The most dissatisfying feature is that this phone only install the apps from tizen store which is not having so many apps you want.So if you are searching for a 4g phone do not choose this one.
