Had the galaxy S4 for over a week, and everything worked great till yesterday. Plugged the charger into the phone, and left it over the night. In the morning, found out that the phone wasn't charging (on battery stats I had a flat horisontal line in the time of charging. Tried to put the charger in again, phone doesn't recognize it. Got the battery out and back in, still no effect. Couldn't connect the phone to computer either.
After the battery run out of juice and phone turned off, tried the charger again. The phone obviously recognize the charger, since it gives a short vibrating alert, and shows the picture of the empty (gray) battery with the frozen loading ring, but the problem is that it won't initiate the charging procedure - battery image goes off after a second or two, and the whole vibration, battery picture sequence repeats every 5 seconds. I have noticed tho that it charges the phone somewhat, since it can be turned on (but only when I unplug the charger), and has some charge, but when I plug the charger with the phone turned on it still isn't recognized.
EXACTLY what happend here. Ill however admit that it happend after i dropped. From about 40 cm, it even landed softly on my foot. wtf is this
