It's been a while my phone is shutting down frequently even after I took it to a service centre. They said the issue has been resolved but it is the same even after I got it back. It suddenly shuts down while playing a game or using any app or even while it is charging. Sometimes it won't even switch on and it takes hours and hours of despair and frustration and it won't even respond to force turn on. Even now it is switched off and I'm writing this from my laptop. So, I request you to replace my phone or refund my money back as this is a brand new phone with no damage at all.
