I have ordered Redmi 2 Prime Phone from MI India. It was haiving some dead pixels on the left side of the screen after 4-5 days these dead pixels become thick black line and screen starts blinking. Now 45 days passed taking follow ups but all is useless. No one is doing anything. Please refund or replace my handset. They have poor customer service center, they always deny if we say to check anything. they have nothing in their hands, they say go and ask to company.
