@STEpark: Can you confirm which System Sound you have selected in Settings > Sounds and Vibration > System Sound? Try heading to Settings > Apps > Calculator > Force Stop > Storage > Clear Cache, then restart your phone to see if this addresses the issue. If not, as a workaround, head to Settings > Sounds and Vibration > System Sound/Vibration Control > Sound > Touch Interactions, and toggle this option off.
Happened to me too.
I don't know how to turn it down /off
Mine too.. It's so annoying.. What about setting system sound.. I did
What about restart the phone.. Yeah I did..
But nothing changed.
When on calculator I pressed either volume key then on the volume graphic that appeared turned this down to off.
Hope this works, it did work for me.
Samsung again, so annoying.
Sorry typo S20Ultra
Same here, just started making noise when typing. Turning the volume down in the Calculator app does nothing. Argh!
