Hi, I was just using my phone today and it drained battery. Thinking that I just needed a charge, I plugged it into a wall charger and let it run. Last time I checked (or was able to check it), it charged up to 15%. The issue now is that I cannot turn on my phone, my computer does not register a device plugged in when I plug it in, and even when I plug it into a wall charger there's no red LED light on the top. My phone is the i747m (the North American version of the i9300, Samsung Galaxy S3) and the last update was Jellybean (4.3 something, just unsure of what the last digit was). I swapped batteries with my friend's S3 (exact same model), thinking that it might be a battery failure but while her phone turned on with my battery, my phone was still unresponsive with her working battery. Every time I try to turn it on (via power button) all I get is the white 'SAMSUNG' words and then it just goes blank again. Any solution or fix to this?
