I have purchased my phone in november. A day before yesterday i got hanged and nothing was happening. After 24 hr it has started reboot and then touch screen was not working. I went to redmi store and they told me that i wll take 6000 rupee for repair. Can you imagine 6000 repair coast which cost of my mobile bilef and too in a service period..
It is just one month old phone and purchased for my parents. It is his first smart phone and got issue like this. I ha e confused them to buy as they were telling it is very costly phone.
