Recently, my wife's 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? She is running CyanogenMod7 on her HTC Incredible.

In Settings - Phone settings

or

In Dialer - Menu -Settings

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

  • I'm not finding either of those in the settings for CM7.1.

  • @roxan Are you sure it's from this version?

  • Actually no. I assumed after reading couple of post this is where it should be. Guess I also have to take my answer down :)

I got this to work under CM 11 by opening the Phone app, hitting the dotted line for settings, then un-checking the "Dial pad touch tones" option. I can't hear the touch tones anymore, but at least I can access my voicemail.

I have an international i9300.

  • My problem was the opposite. Dial pad touch tones was disabled. When enabled, tones started to be transmitted again, though unfortunately annoying touch pad tones are now audible. This is probably changing as Android goes through each iteration, so worth toggling the Dial pad touch tones setting.

I 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.

I had a similar problem of not hearing the touch tones. It turned out to be that the volume for "Music, video, games, & other media" was set to the lowest level. "Settings > Sound > Volume" Maybe this will help someone.

Solution that worked for me is very different:

My mobile is Android, Lenovo K8

After searching a lot, nothing worked to me, and based on Lenovo call support this worked finally.

Network & Internet > Mobile Network > Enhanced 4G LTE Mode [DISABLE]

Disabling this only worked for me, Changing Touch & hold delay to different values [short, medium, long] also not worked!

Hope this helps someone, I struggled with this many years to get it fixed :-(

Definitely this is a bug, however no updates also sent to my phone :-(

On Galaxy S4 I changed to option long instead of normal and it worked:

  • From the Keypad tab, tap Menu Menu icon (located in the upper right).
  • Tap Settings.
  • Tap Call.
  • Tap DTMF tones.
  • Tap Long

I used the dtmf app and now my phone is making the necessary sounds.

    Can you provide the link for the app?
