Sir/mam,
I purchased a brand new redmi note 4 phone32 gb 3 gb ram from flipkart on 4 august 2017. It had been only 14 days since i had received my phone that it stopped working itself. I rushed to the service centre in sector 22 chandigarh and they told me to submit the phone. Neither it was damaged by water nor any physical pressure was put on the phone. My phone is still lying in service centre and they have not been able to detect my phone's issue.
I am really dissapointed with mi services and their phones. I chose this phone despite having so many other options. Pls help me. It's not been even a month now that i purchased this phone. Pls help me in this regard. Phone is in warranty period. Hope to get help from u soon.
