Using Nokia 7 plus since last two months . The device shuts down randomly even when I am using it. I have tried hard resetting it and also taken to the service center but they say they did some software checks and the device is fine but the shutting down problem persists. I have very less apps installed now as I was doubting whether the issue was due to some app but I am not able to figure out. Can someone help and suggest what could be done before I again go to the service center and ask for a replacement.
