Anyone had a problem with their external speaker? I think mine has a loose connection or something, yesterday it suddenly stopped playing any music, notifications, alarms you name it. Gave it a few taps where the speaker was and it started coming back to life. Today it died again and tapping it isn't working so I took out the battery cover and sort of pressed down on it abit and it started working again. What do you guys propose I do? Is this something I can get done myself?
