I was trying to get dust out of my iPhone and I decided to use a tooth pick to use, I didn’t apply a lot of pressure and was careful too. Now my iPhone is kind of muffled/quiet now… Was it because of the tooth pick? What can I do now?
You will need a new loudspeaker. Get the replacement part here and follow this guide up to step 52. After step 52, install the new loudspeaker in, then reassemble the device.
