    I have an unlocked, universal s8 purchased at end of 2017. I've had intermittent problems with DTMF tones, but they are now totally gone, as is any option/settings to change DTMF settings. My old Galaxys had a setting for DTMF, and this phone DID have functioning DTMF when I got it.

    I use TMobile. I have WIFI calling switched off.

    It has most recent update

    I have tried:

    switching off VOLTE and going to 2G/3G network;
    Turning on and off "keypad sounds;"
    Turning on and off "notifications during call;"
    Turning phone on and off;
    Clearing cache/storage in phone app;
    Every other suggestion found on the internet in the many forums that discuss this very problem.

    NOTHING works. I cannot call stores, banks, or even the police without DTMF function!! What happened to DTMF and how do I get it back??

    try factory resetting the device. if that does not work then you can try flashing a firmware update from sammobile.
