I have a OnePlus 8 5G UW from Verizon. At one point soon after I got the phone I was exploring features and I hit the RTT icon during a call. That turned on the on-screen keyboard so I could type rather than talk. I don't need that feature and now I cannot figure out how to turn it off. Many of my phone calls result in that RTT screen turning on and it doesn't turn off if I hold the phone to my ear, it makes it harder to get to other call features, and the disconnect button is located such that I hit it with my cheek and lose the call.
I've looked in the settings for Real-Time Text (RTT). It shows as "on" in the top level menu and the only options for changing it are:
- RTT Operation Mode
- Visible during calls [checked]
- Always visible (Manual)
- Always visible (Automatic)
Does not seem to matter which of those I pick, it will still show up for many calls. There is no "Off" option and if I select "Visible during calls" it does not uncheck the option. When I make a call I don't get the original screen with the easy access to call features, like the keypad and the RTT mode, so I can't try to toggle it off.
Any idea how to turn this off or disable it entirely?
[Update] I've switched it to manual mode. Now every single phone call it asks me if I want an RTT call or a voice call. I pick voice and I get the regular call screen. Annoying every time I make a phone call but it seems that you can't force this feature off once it's turned on.
