Hey! My friend has a Samsung Galaxy Note (just bought it yesterday). Today the phone went black and she's unable to turn it on. If she tries to charge it a battery flashes on the screen with a grey circle in it (cannot post a picture since I'm a new user), however, she can still not turn it on. This occurs both while connecting via USB or a "normal" charger. If connected via USB the computer doesn't register the unit We've tried flipping out the battery and put it back in but still nothing. Anyone able to help us out here?
