    I have this same issue. I've been working with OnePlus for MONTHS on this and they refuse to help. I recommend you sell the device and buy another brand. This company is disgusting.

    Go to settings>system>accessibility and check the settings. Everything should be off except auto-rotate screen.

    It's an issue that Oneplus is "working on" rtt has a bug under Verizon services. I suggest following XDA forums and converting software to the international version. Be aware, the conversion will wipe your phone but if you'll use the oneplus switch app to backup your stuff onto a memory stick or pc, you'll be just fine

    Heads up!!!

    The most recent update T-Mobile released has fixed this problem. (I work for T-Mobile) You may need to put a T-Mobile SIM in the phone and search for the update in settings. #finally

    I have a OnePlus 8 and there is no option to turning off RTT. Has anyone had any luck getting this bug addressed?

    I also am wondering if this bug has been resolved. I have the Verizon UW version of the phone and it does the same thing for me. Only when I download and try to use the stock Google dialer and contacts app. The garbage stock ones that come with the phone actually work. It happened on Android 10, was hoping the 11 update would squash the issue but wrong again. I have been noticing that as I go through this community app, I don't see a lot of resolutions made by the Oneplus developer team. Anyone see something wrong with that? Do they even care about a HUGE bug like this? Buyers remorse.

    I too am disappointed.

    Here is a video demonstrating the lack of ability to turn off RTT.

    I will probably be returning to Google in the future for phones.

    I suppose I'll still take OnePlus over Samsung though.
