Hey guys, so my N4 has done this twice now. I've had my N4 since release, and never had an issue until about 2 weeks ago it shut off and would not come back on. Today the same thing happened. I had to hold the power button +volume down button, of which a window prompt appears with a blue outlined arrow with START pointing to the power button. So, is this a clear sign my N4 is about to permanently bite the dust? Time to finally buy my N5 I have wanted for awhile?
