While setting up my phone, I noticed it responded very slow to my inputs. After I got past accepting the second step (agree to terms and conditions, after selecting the correct language), the screen went out, didn't turn on. I restarted the phone, boot logo came up, but screen remains black. I then restarted it again, and now even the boot logo won't show up. I can see it's running when I connect to my pc, because it shows up as a music player with no data. I also tried restarting it using the volume down and power button, and with the power button and volume button pressed for 30 seconds, but apart from a little vibration the screen remains dark.
Any help on how I can hard reset the device without access to the screen? Or should I just return it and request a new one?
