So I have the Samsung galaxy rugby pro. I love the phone but it's have some trouble. When I plug it in it vibrates once shows the spinning battery turn offs then show the green battery like it's charging. I charged it to 100% and I tried to turn it on. It shows the Samsung logo quickly goes away then it comes back for a longer time. After that it vibrate then it shows the spinning battery and says it has 0% and start to charge it to 100% again. It's like a complete cycle and it's so annoying. Please respond soon I would like to have the phone working asap.
