Cannot use keypad during calls to select call centre options eg i can’t “press 1 to select this option” on my S9

Help!!!

This is an ongoing issue for me and others....I've also heard this is affecting Huawei phones too...I have an S9

The issue: during a call (inbound or outbound) the keypad does not recognise/accept me pressing the numbers...

EG the automated voice at a call centre says "press 1 to select this option" - I press 1 and nothing happens - i actually get a "bleep" tone when i hit 1 but it doesn't register and the automated voice just repeats its message until i get fed up of pressing 1 multiple times....

That's strange, @madfrank7. Have you seen the guide below (from Samsung US) and checked whether the suggested steps enable you to resolve this?:

Please let me know how you get on.

Wow this worked!  I tried everything else and it was driving me nuts!  Thanks

Did you try the * in front of the number? For 1 use *1  I also tried everything but this worked!

What worked for me is to turn off 4G calling

Settings> network and internet> sim choose your sim and switch off VoLTE
