Hello. I woke up today and tried to place a phone call, and there was no sound. I had just used my phone last night, so I don't know how something went wrong. The speaker isn't broken, because when I get a voicemail/turn my phone on or off/press "play" when I'm lowering/raising the master volume, it plays sounds. But when I try to preview my sounds/ringtones, nothing happens, when I press the speakerphone button, nothing happens, and most importantly I cannot hear or be heard during phone calls. I can't tell whether this is a hardware or a software problem, and would like to know if I can fix it without professional help. Thanks in advance! :smileyhappy:
