    I have a Motorola G4+ that recently took a bath in motor oil. Long story short, it was in my pocket, oil change gone wrong, and it wound up soaked as well as my pants.

    I had a case on it, which protected it mostly, but there was obviously some oil in my speaker and microphone. Turned it off, have liberally sprayed the mic and speaker with electronics cleaner many times.

    All is well, except the microphone does not appear to work during a phone call.

    What puzzles me, it picks up fine if I record video. I have a messenger app called WhatsApp, and if I record a voice message (and yell) it can be heard ever so faintly. Phone calls, text to speech text messaging, voice searches via Google, none seem to work.

    Can anyone shed any advice on this? Has anyone opened one up? I've dissected and repaired a couple Samsung phones and an LG G4, so I'm not terrified of opening it up if I can get the correct screwdrivers and the mic can be replaced or cleaned better.

    But since video picks up fine, I'm now not sure that that is the issue. Are there multiple mics? Are there different sensitivity settings for different functions?

    If there is an app that can work around it, since obviously the microphone(s) do work, I'm all ears. That would suffice. I use my voice to text often, but rarely hold phone conversations.

    I'm beginning to wonder if my problem is due to the headphone jack.

    Recap:

    Whatsapp messages can no longer be heard faintly. Now they just sound as static.

    On a call, my audience hears nothing, but I hear an echo of what i say in my own ear. Voice search, text to speech does not work. Both mics appear to work when recording video. I sprayed the mic out liberally with electrical contact cleaner, but since it appears to pick up under certain situations, I'm inclined to believe it isn't clogged or muted with oil any longer. Which is also partly why I am reverting to wondering if it's a headphone jack malfunction.

    I've read of phones acting wonky when headphones are plugged in during a call.
