RTT Won’t Turn Off On Android | Quick Fix Guide

What Real-Time Text Is And Why It Stays On

Real-time text (RTT) lets text flow during a call so both sides can type and read without taking turns. It replaces older teletype (TTY) tech on modern networks and ships on most phones by default. Carriers back it to meet accessibility rules, so you’ll see an RTT button in the dialer or a banner in call screens. In some builds, that button can stay visible or calls can start in text mode if a toggle is set to “always show.”

Two things make it feel stuck. First, the toggle lives in different places on different brands, so you may switch the wrong one. Second, cached dialer settings sometimes keep a stale state. The good news: you can switch it off cleanly with the steps below, and if your device shows only “always show” or “show during calls,” you can still stop calls from launching in RTT.

Fast Fixes At A Glance

Turn Off RTT On Pixels And Many Stock-Like Phones

On Google’s dialer and close variants, the switch sits in the Phone app.

1. Open Phone → tap the three-dot menu → Settings.
2. Tap Accessibility → RTT (or TTY/RTT on some builds).
3. Turn RTT off. If you only see a visibility choice, pick Show only during calls and make sure “Answer as RTT” is off.

These paths mirror Google’s own help guide for Android accessibility and real-time text. If your menus differ, the search bar inside Settings finds the page quickly. Place a call from Recents to confirm the change sticks now.

Disable RTT On Samsung, Motorola, And Others

Samsung

Samsung places the control in either the Phone app or Accessibility:

• Phone app path: Phone → Menu → Settings → Real-time text → set visibility to during calls or turn it off.
• Accessibility path: Settings → Accessibility → Hearing enhancements → Real-time text.

Some recent Galaxy builds only offer visibility choices. Pick during calls so the dialer won’t launch in text mode.

Motorola

Motorola models often tuck the switch under Accessibility:

• Settings → Accessibility → Real-time text (RTT) call → toggle off.

Carrier Variants And Flip Phones

Carrier firmware can add an RTT tile or move the setting. If you use a branded device, look in the Phone app first. Feature phones and flips usually keep it under Accessibility or Call Settings with a simple on/off or visibility choice.

If The Toggle Comes Back: Deep-Clean The Phone App

When a switch seems to revert by itself, stale cache is a common reason. Cleaning the dialer resets its stored preferences and clears the stuck state.

1. Go to Settings → Apps → Phone (or Dialer on some brands).
2. Tap Force stop, then open Storage → Clear cache.
3. If the issue persists, tap Clear storage/data. You’ll keep contacts and call ability, but the Phone app’s preferences and quick filters reset.

Place a fresh test call after each step. If audio returns and the text banner stays hidden, you’re set.

Understand What You Can And Can’t Change

RTT is part of modern calling standards. U.S. rules endorsed by the Federal Communications Commission moved networks toward this tech years ago. That’s why you see the feature on nearly every recent device. Even so, you control whether your calls start in text mode and whether the shortcut sits in view.

Two common limits exist. First, some firmware only lets you hide the button during calls, not remove it from the dialer completely. Second, a carrier profile can pin the feature on branded phones. In that case, updates to the Phone app and carrier services can restore full control.

Extra Steps If Calls Still Start In Text Mode

Update Phone, Carrier Services, And Dialer

Out-of-date apps can keep old behavior. Open the Play Store and update the Google Phone app, Carrier Services, and any OEM dialer or call plugin.

Reset Network Settings

If a carrier profile glued the behavior, a network reset can refresh it.

1. Settings → System → Reset options → Reset Wi-Fi, mobile & Bluetooth.
2. Reboot, then confirm that RTT stays off during a test call.

Check Call Accessibility Shortcuts

Some skins add a call accessibility shortcut. Turn that off so the dialer doesn’t flip into text during calls.

Try Safe Mode

Third-party call recorders or dialer add-ons can interfere. Boot into Safe mode, place a call, and see whether text still takes over. If the issue vanishes, remove any call-related add-ons.

When You Might Keep The Shortcut

If hearing or speech makes voice calls tough, the feature can help in daily calls. It sends text as you type, and both sides can write at once. Android also offers Live Caption, Live Transcribe, and Sound Amplifier for different needs. If that’s you, keep the button visible but leave default calling as voice.

Myth-Busting: Five Common Misreads

• “It’s a virus.” It’s a built-in accessibility feature, not malware.
• “Turning it off breaks emergency calls.” Voice calls still work. Text during calls remains available when you re-enable the feature.
• “Removing the icon deletes transcripts.” Hiding the button doesn’t erase past call transcripts stored by the dialer.
• “Only one party can type at a time.” Both sides can write at once; that’s the point of real-time text.
• “It’s the same as SMS.” This runs inside the call, not over your texting app.

Step-By-Step Troubleshooting Checklist

1. Open the Phone app → Settings → Accessibility → turn the feature off.
2. If you only see visibility choices, pick during calls.
3. Force stop the Phone app → clear cache → test a call.
4. Clear the Phone app’s storage/data if the banner returns.
5. Update Phone, Carrier Services, and system apps.
6. Reset network settings and reboot.
7. Test in Safe mode; remove call add-ons if the issue disappears.
8. If a carrier build locks the switch, contact customer care for a profile refresh.

Why This Feature Exists

Modern networks moved away from legacy teletype hardware. Real-time text was adopted to provide text during calls over IP voice. It helps people who are deaf, hard of hearing, deaf-blind, or with speech disabilities place and receive calls without special terminals. That’s the reason the option appears broadly across Android phones and why carriers surface it inside the dialer.

Link Out To Official Guidance

For menu paths, see the Android real-time text help. For background on network backing, read the FCC’s real-time text page.

What A Greyed-Out Switch Means

On some carrier builds the toggle looks locked. That doesn’t force text on every call. Pick during calls inside the Phone app, update the dialer and Carrier Services, then restart. If the icon still takes over, ask the carrier for a feature profile refresh.

Privacy, Transcripts, And Storage

When you use text during a call, the dialer may keep a transcript for that entry in your recent calls list. Hiding the shortcut doesn’t erase previous transcripts. If you don’t want text logs, avoid turning the feature on during calls and clear individual call details from the recents screen. The logs live inside the dialer app, not inside your messaging app.

Why Calls Sometimes Go Silent

When both ends default to text, the audio path can be muted at call start. That’s by design so typing stays clean. If you hear nothing, look for a T icon or an on-screen message about text mode. End the call, turn the feature off in Accessibility, and redial. You can also switch to voice during the call if the on-screen option appears.

When To Call Your Carrier

If the switch is locked, calls still launch in text mode after you clear data, or you use a carrier model that hides the menu entirely, reach out to your carrier. Ask about a feature reset for the line and whether your plan profile pins text during calls. Store staff can also check for a firmware update that restores the menu path.

Trusted References For The Setting And Its Behavior

Google’s Android help pages document how to use and switch this setting. In the United States, the Federal Communications Commission explains why carriers back it and how it replaces older teletype systems. If your menus don’t match the paths above, use the Settings search box for “RTT” and you’ll land on the right screen.
