To remove RTT from your Android phone, open the Phone app, tap the three-dot menu, go to Settings, then Accessibility, and turn off Real-time text (RTT) or set it to Not visible. The exact label and location of this setting vary by device manufacturer and carrier, so you may see options like RTT, TTY/RTT, or a section named Hearing enhancements.
What is RTT on an Android phone
Real-Time Text (RTT) is a feature that lets you send and receive text messages instantly during a phone call, with each character appearing as it is typed. RTT uses IP-based technology for real-time text conversations over the internet. On Android, RTT support is implemented through device and carrier configuration, controlled by the device config flag config_support_rtt and the carrier config flag CarrierConfigManager.RTT_SUPPORTED_BOOL. RTT requires both parties to have compatible devices and a network that supports the feature. Because of this, the user-facing menu path is not universal across all Android phones.
How to remove RTT from your Android phone
- Open the Phone app.
- Tap the three dots menu, then tap Settings.
- Open Accessibility or a similarly named section such as Hearing enhancements depending on your device build.
- Tap Real-time text (RTT), RTT, or TTY/RTT if that is the label shown on your device.
- Turn RTT off, or set it to Not visible / Show only during calls if the phone offers visibility choices instead of a full off switch.
If you are troubleshooting other audio or call issues, you may also want to look into voice assistant and microphone fixes to ensure your phone's call quality is not affected by unrelated settings.
Why the RTT menu path varies by device
This means the exact label and location, whether it appears under Accessibility, Hearing enhancements, or a different section, depends on the manufacturer’s skin and the carrier’s configuration. Disabling RTT can reduce data usage during phone calls. Disabling RTT can improve battery life during phone calls. RTT can occasionally cause performance issues like slowing down the device or causing freezes.
Does hiding RTT block all RTT calls
No. One documented behavior is that setting RTT to Not visible only hides the RTT calling button from the phone UI; it does not necessarily stop the phone from receiving incoming RTT calls from other users who have RTT enabled. On some builds, turning RTT off removes the option entirely, but the feature may still be triggered by calls from other RTT-capable devices.
Frequently Asked Questions
Does Android have one universal RTT off path?
No. Android’s official documentation says RTT support can be controlled by device and carrier configuration, so the menu path can vary by model and build. You may need to look under Accessibility, Calling settings, or Hearing enhancements depending on your phone.
Will turning off RTT on Android stop all RTT calls?
Not always. One documented behavior is that hiding RTT can remove the button without preventing incoming RTT calls from other users. Turning RTT off fully may stop outgoing RTT, but incoming calls from other RTT users may still connect with the feature active.
Where is RTT on iPhone?
Apple documents it under Settings > Accessibility > RTT/TTY. Turn off RTT/TTY to stop RTT from being used on the iPhone.
What if my phone shows TTY instead of RTT?
Some Android builds and carrier configurations use TTY, RTT, or TTY/RTT interchangeably. If you see TTY instead of RTT, tap that option, it typically controls the same Real-Time Text feature.
Can I remove RTT from the Phone app without going through Accessibility?
On most Android phones, the RTT setting is located inside the Phone app’s Settings under Accessibility or a similar section. There is no documented alternative path that bypasses these menus. If you can't find the RTT settings, consult the user manual or contact the manufacturer's support.
