s4 suddenly stopped charging and "dock connected" message appeared
So up till 15 min ago, my 10 month old unrooted not damaged samsung s4 was working fine. Then as I connected it to the charger because the battery was low, it stopped recognizing the charger and wouldnt charge, i checked it on several USB chargers and wall mount tradiitonal ones and my PC but it just would not recognize. Then a message appeared saying "dock connected" and then it disappeared and a new message came "HDMI connected" thats when i switched it off to restart it.
Suddenly, the screen went black and an Android man popped up saying Downloading Do Not Turn Off Target. I waited a few minutes and then did a batt pull and its not been charging since and the Dock and HDMI messages keep repeating!
What should I do!
