I noticed last night that my Samsung Galaxy wouldn't charge when I plugged it into the computer. I use my USB to charge it since it's a European phone and I don't yet have an adaptor for the charger. Anyway, I figured it would last me the day without being charged, but then a little while ago I had a go at charging it again. I borrowed my sister's Samsung charger and plugged it into the wall, but it still wouldn't charge. I've tried taking the battery out and leaving it for 5-10 minutes at a time a few times now, but nothing is working. Does anyone know what could be wrong with it?
