    I recently bought a Lumia 925 i will be using in future (maybe... if i'm unable to repair my Lumia 820).

    But this phone hase some major problems. I can't really use it as a phone right now. It's just for mobile Internet/WhatsApp right now. That's because the primary microphone doesn't work and the earpiece acts weird.

    Symptoms are:
    - Primary microphone does not transmits any voice during regular phone call. Only weird static noise
    - Earpiece transmits a very distorted/buzzing voice of the caller. So it works somehow... but not usable
    - If you switch to "handsfree mode" that it uses the speaker on the back and the secondary microphone on the top... everything works perfectly fine (but i won't use that option in public)
    - WhatsApp calls work perfectly fine on all mics/speakers/earpieces

    Are there any known solutions to that kind of issue?

    Kind regards,
    eviltrash
