Rispondi a "Microphone not working when on whatsapp call"I had a problem like this in my iphone 6s. Front mic didn’t work or had low sound in all video calling (whatsapp, facetime, google duo etc). After reinstalling all apps or system factory formatting it didn’t fixed. After that I changed the battery with unscrewing screen, facetime has fixed and had great sound, but whatsapp has normal or low sound. I think my problem has fixed.
