Hello, my microphone does not work on speaker mode calls, but it works on normal calls and WhatsApp voice messages. What part do I need to change on my phone? Thank you very much!
Off the top of my head, I think it’s the charge port you need to change. Check the bottom left of the phone to make sure there isnt any gunk built up over the pin hole sized mic port. Even in a case, I have fixed this very issue by cleaning the phone.
