Received the phone yesterday from Flipkart. Yesterday the phone shutdown suddenly while I was just using whatsapp. Its instant black screen and then I had to use the power button to switch it on. Today morning I was changing the notification tone and it went to instant shutdown again. No gaming or overheating happened before this. Yesterday the battery was around 50% and refresh rate was 120hz when it happened, today around 90% battery and 90hz refresh rate. The phone runs normal,
Please tell me what to do. I still have time to deal with Flipkart. Today is the second day I have this brand new phone with me.

Will flipkart give a refund? How to get a 1 to 1 exchange?
I just spoke to the service center, they said that I have to keep the phone with them for a day or more and they will check if there is any problem.

Isn't there a return and refund period for purchase from Flipkart? Many users here have gotten a refund.

Flipkart has a 7 days replacement policy. They don't have a refund policy.
If many have got a refund, they I can hope for it. But what I need the most is a solution, as I'm not looking for the money but the device as it is intended to work. Any moderator or expert has a solution to this problem? If I take this to the service center then they'll take time to do anything.
