I've noticed on several occasions that the earpiece speaker in my iPhone 5 is uncomfortably loud during phone conversations. Yes, I can just hold the phone further from my ear, but in quiet environments the buzzing of the voice on the other end can be heard from quite a distance. To clarify, I'm not referring to the main speakers (speakerphone) or using headphones.
Is there any adjustment I can make to enable lower volumes? I've searched and seen many results about boosting the volume, but I want to do the opposite.
If this is an unusual problem, could it be a hardware issue specific to my phone?
I've subjectively compared the volume of the iPhone 5 to an LG Optimus G Pro, and the middle volume of the Optimus sounds higher than the lowest volume on the iPhone.
