    hello everyone :
    I'm using OnePlus 7 pro long time ago and I'm so happy with it since it's a very powerful device, but I'm facing a trouble with phone calls because most of people calling me is hearing their voices echoes and it's very annoyed.
    - I've tried to hard reset the phone and it's still not working
    - I've stopped my Google assistant and also it's working
    I've tried to install a new software from the OnePlus dealership support and also it's not working

    anyone have the same problem? and any solutions for it ???!!!

    I remembered that I have insert the SIM tool pin by mistake in the top microphone hole; anyone know if it might be the reason for the echo sound during calls ????

    not really. receiver should be speaker as well by designed. I dun think that is speaker / Mic hardware problem if it work well unless phone call. Maybe try to turn off VoLTE / VoWifi.
