    Phone as in the title. Overnight it stopped working almost completely. The voice recorder did not record anything, the decibel meter showed around 80dB all the time. I blown it with compressed air and it dropped to normal values.

    The voice recorder caught the loud speech very poorly. It's OK on the headphones.
    What are the chances that only the microphone is damaged?
    If the headphones are OK, does it mean that the audio path is OK?

    I went to one of the services and said it was a difficult topic because the phone is glued and it is easy to damage the display when taking it apart. I laughed and left. I dismantle the phone myself in 5 minutes.

    The microphone is soldered to the board. Can someone with the concept of soldering be able to solder it or look for someone who is sitting in the phones ??

    Best regards.

    You have to have a hot air and experience because the microphones are so delicate and easy to damage.

    I know that the transformer will not be soldered.
