I am currently using this mia1 phone of xaomi .I think this is one of the best phone launched by xaomi and it is the revolution in the category of phone because they provide us dual camera phone under 15000r indian rupees .It functions properly because of having 4gb ram and I think this is the first phone of any brand to come only in one varient that is only only pf 4gb ram .the best thing about this phone is that I like the camera section very much and it has the best model in term of design.
