Do you want to buy a Samsung Galaxy Core? Beware, think twice. I am having a terrible time with it. The phone hangs, you cant recv call at times. The message it always shows. In fact any time. Unfortunately, the process.com, Google process apps have stopped and actually unfortunate are those who have purchased Samsung Galaxy Core.
Qulacom is just nonsense and it will make you out of your sense. I keep throwing my Samsung Galaxy Core every now and then.
