I saw this in another forum somewhere.
Settings -> Call -> TTY mode -> TTY VCO
It works for me.
Thanks! I tried it this morning and now I can ditch the extra gear. I'm surprised this isn't better documented in the owners' manual!
I went back and double checked the owners manual and there is no reference that I could find about this setting. I also never heard anything from the complaint I filed on the HTC site. Since it's such an easy fix, I'm surprised they aren't advertising it more, since apparently a LOT of people were upset about this.
Never underestimate the ability of a company to misjudge the importance of the little things. In all actuality, it's not a huge issue, but it's one of those things that nobody should have to devote a second's thought to.
All told, I am really enjoying this phone. The battery is lousy, but it seems like all the HTC phones of this size have those issues, and I knew that coming in. Disabling the LTE radio has helped a bunch, but I want to squeeze a few more hours out of a charge without springing for the extended battery. Installed Das BAMF last night hoping to get it through a work day.
