Hi there! Sometimes when I send voice notes in WhatsApp my friends cant hear whatever I say, I thought that it was WhatsApp’s problem until I made a call with the default phone app and turned on the speaker, whenever I speak ’normally’, the microphone works correctly but when I use speaker, WhatsApp, Skype or similar apps (even in-game) the mic doesn’t work
it uses a secondary microphone located at the top.. did you changed lcd?
What if the LCD has changed ? Does it affect the microphone, I bought this phone used so IDK what’s replaced in it. I opened it up and cleaned the mic ports now the bottom works well but the top is too weak.. and why does my phone switch to the top mic in loud speaker mode ? Thanks (Galaxy S4)
