This morning it happened: MY NEXUS 4 WAS DEAD ! BLACK SCREEN !
Pushing the power Button had no effect and when i tried to charge it there was no battery symbol.
I tried everything with success !
1. Remove the Nexus 4 from the charger.
2. Press and Hold Power + Vol Down for 20 seconds
3. Connect the Nexus 4 to the Charger AND ….
4. Black Screen Problem should be solved !
if not try again. If nothing helps and you had problems charging you Neuxs 4 before. Try another usb cable to charge you phone. Maybe you charging port is broken. If you have a friend with a Qi Wireless charging station give it a try.
