I dropped my Nexus 5 on tile. It is running Kit Kat never been rooted. I picked it up and tried to unlock it and wake the device. It did nothing. I plugged it in to the charger and it showed the black and white charging symbol. I then pressed the power button and it turned on. It is now on and the power button and volume buttons don't work. I unplugged it and now the charging symbol went away. I plugged it back in and won't come back. The notification bar says charging 51% even when unplugged. RIght now it is plugged into a wall charger and I have WiFi on while I back up stuff. I plugged it into my copmuter and it shows nothing. Please Help!!!!! I don't know if it is dying in my hands or if it is actually charging or what. I put it on the wireless charger and it does the same thing.
