I was hearing a lot about this budget killer phone and I recommened my tuition teacher and he bought only because I said he used it for some days . There was always heating problem in that but he didnt care for that . It was 5th or 6th month the smartphone blasted in his side pocket . Luckily it was not his chest pocket and he got injury on his leg. He told this to me so I said they ( xiaomi) will replace it but they didnt replaced it and said that it might be your fault it get over heated and blast. My tutor tried his best but he didnt get new phone nor refund . So it is very bad smartphone according to me as it gets heated most of the time and can blast at any time like my totors
