    Hey,
    I have the following problem with Huawei P9 Lite. The microphone does not work completely during calls, but the sound recorder is recorded on the recorder. I exchanged the entire bottom plate with the microphone, I inserted the softa and still the same problem.
    greetings

    Enter * # 2846 #. You can cancel further tests by pressing the switch and then the volume key down. Do this until you get to the top and bottom microphones test and check that they both work.

    I will tell you that it looks bad. This is VNS? You would have to measure if there is a microphone supply voltage and the PMU is under the solder screen. Do you have a diagram? If not, see if you can measure them on the microphone board. Look carefully at the connector on the disc, whether it is damaged. Third thing you've probably already done is check if the microphone hole in the housing is clogged.

    Cousin: Girlfriend wrote that the part mentioned. Since the substituted plate is the only thing that is a multimeter microscope and checking in turn. The substitute band is left. Phone after flooding?

    The tape did not unfasten this connecting bottom plate with the upper one - at the bat connector. At the bottom of the connector you have a piece. Check it out.

    In my case, the tape turned out to be a fault, after the replacement the microphone works, even the old plate has come to life. I'm just wondering how the tape could have broken, I understand if it was a slide phone but a hmmm brick.

    Thanks to everyone for the answers. My phone was supposed to go to the trash but first I checked if there was anything else I could do. Huawei p9 lite 2017. Suddenly I look and see to clean the microphone. I had the same problem. After cleansing it worked. Thanks again. :)
