I replaced the back of my phone with a new black one, and after putting everything back together, the ear speaker is not working. The speakerphone/game sounds speaker is working, as well as the headphones if I put them in. I took off the screen three times and put all 3 cables in again to make sure they are in right, and it is not working yet. Also, when calling voicemail to test the speaker, when I change the volume it just shows a speaker, it does not say "headphones" so that is not what is causing the problem... Thanks for any help!
