So my screen and somewhere internally has been suffering moist/liquid damage. Most noticable at the bottom right of the screen. Question is, since while I can hear the person on the other end though they can’t hear me unless I apparently turn on the speaker or use my earphones , is it the loud speaker/speaker or the microphone that’s damaged? There’s better sound when using earphones and even with it onfull volume it’s still pretty ’low’ without earphones.
There is a microphone located at the bottom left of your phone. Left of the charging port. This microphone is soldered onto the Charging Port dock assembly. You can buy a whole new charging dock assembly for your iPhone 6 to fix this issue. That is if the water damage is only on the microphone and near the dock connector on the logic board where it is also near the battery connector. Part is pretty cheap to replace actually: Charging dock assembly: iPhone 6 Lightning Connector and Headphone Jack Loudspeaker: iPhone 6 Loudspeaker How to replace it: iPhone 6 Speaker Replacement iPhone 6 Lightning Connector Assembly Replacement
