My relative is running CyanogenMod 7 on her HTC Incredible. Recently, her phone started acting weird in that when connected in a phone call, pressing the touch tone keypad is not working. You can hear the tone being pressed in the speaker, but the other end of the phone call is not getting the tone transmitted. What might be causing this, and how could I go about getting this fixed?

You'll find an option for DTMF. Try changing that to different values. It might even have been turned off.

Commented Oct 14, 2012 at 12:56 @roxan Are you sure it's from this version? Commented Oct 14, 2012 at 17:58Actually no. I assumed after reading couple of post this is where it should be. Guess I also have to take my answer down :)
Commented Oct 15, 2012 at 3:35I don't even know if this will work, but after having this problem intermittently on an AT&T Samsung Galaxy Note 4 and not being able to find DTMF settings anywhere, I found this: Settings > Device > Personalization > Accessibility > Dexterity and Interaction > Press and hold delay (options short, med, long)
On a T-Mobile Samsung Galaxy Note 4, it was similar but not exact: Settings > Personalization > Accessibility > Dexterity and interaction > Press and Hold delay (options short, med, long)
I selected long.
I can't take credit for this; the idea came from someone making a post about a Samsung Galaxy S7, whom I wasn't able to thank but wish I could.
