never buy a xiaomi product. I had bought a redmi note 4 on 24th March. But it was heating up to 48°c so I got it exchanged within 2 days of receiving the phone. Within 11 days do pixels started appearing all over the screen. When I took it to the Hazra service center in Kolkata they said 'all redmi note 4's have do pixel, come back when there will be two to three times more dot pixels than at present'. But somehow on forcing them they changed the display. Now after two more months my battery back up has gone down to two hours. And 70% of my pdahas come out of the frame. So I brought it to the asansol service center they showed me the battery and it has swollen immensely. But they are not servicing my phone because the Hazra service center had not sealed it. They want me to take it back to Hazra service center. So basically I have to spend 2000 rupees in traveling to get my phone repaired for free. Never buy an xiaomi phone. Their sevicing is even worse than their phones. never buy a xiaomi product.
