Problems with mic & speaker on LG G2

Hi all don't know if I'm on the right forum or where I would start to look for the right one but... I have a lg g2 and I'm having some problems. My mic doesn't work right when the phone is not on speaker. It's not really a software problem because I poked the mic hole with a needle. When the phone is on speaker the mic works fine. So I'm wondering if there is a way to modify the telephonyprovider apk so the phone uses the same mic settings for non speakerphone conversations. So that people can hear what I say and when they talk back it doesn't play through the back speaker but from the phone speaker. I'm not great with coding or programming or anything I decompiled the apk and have been looking for something but can't find it. So can anyone help me fix this or can I send somebody the apk so they can fix it.
