Phone works fine till an year. After that it stops working suddenly. No response. And when I give it to Xiaomi care they said we have to replace motherboard of this device worth 6500. I have purchased this device at 11k and now I have to spend 50% of its price to make it work again. This is the first device I used from Xiaomi and I think its the last. Because I searched the web about the problem and there are many users face that same motherboards problem.
