    My cell phone went through the wash, I'm pretty sure I got all the water out
    of it. It works again, except that the other person can hardly hear me.
    Just wondering what damage water can do to screw up the microphone, and
    perhaps if there's any way to boost the gain of the microphone.
     
  2. I'm surprised it works at all. I'd be just as surprised if it were fixable.

    Time for a new phone.

    Take it apart as much as possible and place it in front of a fan for a
    day or so. It should be fine.

    I am surprised it still works at all! It is possible that there is still
    water or humidity on the circuit board, or even in the microphone. The
    proper fix would be to replace the defective parts if necessary. There are
    no so-called pots to adjust in these. The set-ups for most cell phones are
    all done with interface softwares using dedicated calibration systems. You
    should have mentioned the make and model.

    Considering the low cost of these phones, they usually do not pay to
    service, unless the fault is very minor. When signing for some types of
    plans they even give away most of these models as part of the plan.

    Since you have nothing to lose, I would try drying it out with low heat.
    For example, if you live in a dry desert area, just put it outside in
    the sun for a day. Or remove the battery, put the phone on a plate,
    turn your oven to 200 degrees, put the plate in the middle rack, leave
    the oven door open just a bit for air circulation, and let it "bake" for
    several hours. If you can arrange a small fan (like a muffin fan) to
    circulate the air around it, that will help. Or put a small bulb (25
    watts) in a table lamp, and somehow balance or support the phone on the
    shade above the bulb. Turn it over occasionally. The column of warm
    air rising from the bulb will heat the phone and tend to suck out any
    moisture.

    Any source of modest heat should be as good as any other. Air
    circulation (to carry away the moisture) is important. The process will
    be faster if the air has low humidity.
