So My iphone speaker stopped working yesterday and I checked forums. I read that blowing into the jack may help so I blew into the charging port and it starting working, but my phone never showed any devices connected to it. Then today it did it again so I blew once more and it worked for a second and stopped. I realized after a few blows that it was working when I blew into the speaker, not the charging port! Now, nothing is working! Whats the problem?
