There are a few reasons as to this why this may have happened, I'll start from the top being most probable to the bottom being least probable: 1. The front camera flex / ribbon cable assembly has a physical tear on the cable cutting the line to the earpiece speaker connection. 2. Alignment issue with the front camera ribbon cable and earpiece speaker. 3. The front camera FPC connector (the ribbon connector on the logic board) has bent pins. 4. The earpiece speaker has gone faulty somehow and needs to be replaced.
