I buy the redmi 3 s prime before 1 month ago.newly handset has some problem in cemra. I requested to customers care. He came to me and just see my phone. He only done formality then he say we can not exchange your mobile. When I m charging the phone it become hot. And now slowly slowly has been hanging problem start. Sound is good. Android phone is always easy to use. Style and design not bad but China product Is not reliable
