My galaxy s4 recently stopped working. Last week i was having problems with the phone turning itself off even though it still had sufficient battery. Id remove battery and reinsert and it would be fine. Then one day it wouldn't turn on. Remove the battery and reinsert and Samsung s4 logo would appear and then disappears and nothing else. would not charge or turn on. I figured it was a faulty battery so i ordered one online. I received the replacement today and it worked for about two hours then had same problem and wont turn on or charge. Help is greatly appreciated
