"Why won't my Samsung Galaxy S II charge?"에 답변It's an issue of samsung devices when battery is "too empty". The Problem is now that the samsung charger only starts to charge if it get's a response from the device if not it won't release any current for charging. The solution is that you need a charger which doesn't uses this technique, for me an old apple charger works. Most of the old chargers with currents below 1 A should work. When the display then shows the battery bar you can change to your normel charger faster charging.
