When a contact on my G3 needs the phone to send extra tones (for calling cards for example), the phone will send the tones so fast that the receiving side will not register.

For example, a contact phone number is saved as 555-123-4567;999999
The phone will pause at the ";" and ask me to press a button to continue.
When I press it, the 999999 are sent in less than a second, all bunched up, and the other side of the call cannot make sense of it.

Used to work great on my other android phones, seems to be a problem with the G3.

 

Yes, the comma will add 3 seconds. But if there is a sequence of numbers following the comma, they will be sent in the same way, too fast to register on the other side.
I could put one comma between each number, but it would make it take too long to dial a full number....

I think it's clearly a bug with the G3 phone app. But I have no idea how to report it to LG...
