I own a Metro PCS Samsung Galaxy Indulge 4g Android cellphone. I don't hear the phone ring when I get a phone call, email alerts and so on. I can't even listen to the music on my phone. I cannot use the speaker phone to talk to someone or listen to voice mail messages. I went to the store where I bought the phone and told them the problem. They said that it was the volume on the phone. Whatever! So I really don't know what to do, help here.
