What Is Real-time Text On Samsung


Use real-time text (RTT) with calls

Real-time text (RTT) allows you to converse with someone over the phone while using text. There are no additional accessories required for RTT to function in conjunction with TTY. Please keep in mind that the information in this article may not be applicable to all devices. In order to determine whether or not RTT is compatible with your device and service package, contact your carrier. RTT consumes call minutes in the same way that a voice call does.

Step 1: Turn on RTT

To enable RTT, go to the app settings for yourPhone.

Step 2: Use RTT

You can use RTT to make a phone call, or you can switch from voice to RTT while on the phone with someone.

Make a call with RTT

Note:If you choose “Always visible” in the Phone app’s settings, you will have access to this feature.

  1. Open the Phone application on your device. Choose who you want to call: RTT should be pressed. While the phone is ringing, an offer to join the RTT call is shown on the other person’s computer screen. Enter a message in the text area once the other person has responded. During the typing process, the text that you input is visible to the other person. When you’re through with the call, use the End call button. The call bubble will go to the bottom right corner of the screen if your call has been minimized.

Switch from voice to RTT during a call

Note: If you choose “Always visible” or “Visible during call” in your Phone app’s settings, this option will be available to you. You have the option of switching to RTT on any call, regardless of whether you initiated or received the call.

  1. During a call, press the RTT button and type a message into the text area. During the typing process, the text that you input is visible to the other person.

Merge, hold, or switch to voice

These choices are only available on a limited number of carriers.

Tips for using RTT during a call

  • In contrast to chat messaging, the text that you type appears to the other person in real time when you send it. To provide an example, if you make an error and then remove it, the other person will be able to see both the error and the deletion
  • Even if you have “Not visible” chosen in your Phone app’s settings, the other person might want to switch to RTT. RTT calls are accompanied by an audio stream. To mute or unmute your microphone, select Mute from the menu bar. It is possible to have numerous RTT calls running at the same time. When you need to contact emergency assistance, you can use RTT. In the case of some carriers, RTT is accessible for emergency calls even if you have the option “Not visible” enabled in your phone app’s configuration
  • When traveling outside of the country, RTT is not accessible.

View a call transcript

  1. Open the Phone application on your device. Select Recents from the drop-down menu. Call information may be accessed by tapping the call button. See the transcript by using the “See transcript” button.

Delete a call transcript

The following are the two methods for removing a transcript from your computer:

  • Calls from this number will be deleted from your call history. Learn how to remove your phone’s call history. Android settings allow you to clear the data associated with the Phone app. Learn how to delete app data from your device.

The call transcript is solely saved within the Phone app on Google Pixel smartphones, and other applications are not allowed to see or use the information included in the call transcript. Other gadgets may operate in a different manner. In order to learn more about how your transcript is saved, contact the maker of your device.

What is an RTT call? How the text accessibility feature lets you send real-time text messages

  • RTT, often known as real-time text, is a text messaging service that delivers text messages as you write them, without the need for you to push the send button. A wireless device such as an iPhone or Android phone that uses IP-based technology on a network that supports RTT is required for RTT to function properly. The use of RTT can reduce the need for specific equipment for device users who are deaf, deaf-blind, or have speech-related difficulties.

While making or receiving a phone call, you may have seen the abbreviation RTT or T at the top of your phone’s display screen. RTT is an abbreviation for “Real-time Text,” and it refers to a function that communicates the text of your entered messages to the intended recipient in real time. Users who are deaf, hard of hearing, deaf-blind, or have a speech-related handicap regularly utilize this feature, and it can be critical for callers who are deaf or hard of hearing in an emergency. On December 31, 2017, the Federal Communications Commission (FCC) issued an order requiring cellular providers and manufacturers to develop RTT-compatible networks, a downloadable RTT application, or a plug-in that would enable the accessibility feature.

Local and regional service providers, as well as resellers, must have cellular devices that support real-time text by June 30, 2021, or face a fine.

What is an RTT call?

For years, the Federal Communications Commission (FCC) mandated phone service providers such as AT T, T-Mobile, and Sprint, as well as manufacturers, to support TTY technology — sometimes known as Teletypewriter devices. TTYs, which were originally designed for landlines, allowed users to send written messages over phone lines. TTY technology, on the other hand, became increasingly onerous for mobile phone users as voice conversations switched to wireless phones and devices. That’s when the Federal Communications Commission (FCC) stepped in and established RTT, or real-time text technology.

Abbey White/Insider Photographer Real-time text (also known as RTT) is an assistive technology tool that allows messages written from a cellphone to be transmitted in real time as you write them to a recipient.

The receiver will then be able to view the message as it is being typed and react to you in real time at the same time as you are writing.

Because these instant message transfers are designed to look and sound like voice conversations, phone users with impairments benefit from greater ease-of-use and independence, which may be vital in an emergency.

For device users, RTT eliminates the need to purchase specialist equipment in order to send real-time texts on their wireless phones. It also provides them with a great deal of freedom and accessibility while utilizing wireless devices.

How RTT calls work

Unlike TTY, which requires both parties to take turns, captioned telephony allows RTT users to see their real-time text captions stream in combination with their voice during a telephone conversation. TTY also does not support a wide range of languages, but RTT offers the advantage of integrating characters, different languages, and emojis, among other features. When you use RTT, your messages are shown on the screen as you enter them. Android/Apple Using RTT calling, you may make calls to other wireless phone users — including people and companies as well as government agencies and other RTT and TTY users — regardless of the network or device they are using.

Initiating and receiving calls via RTT may be accomplished by dialing the same ten-digit numbers that are used for voice calls, with usual fees applicable depending on your carrier.

The function is automatically activated on some devices; however, in order to utilize RTT on other compatible devices, you must enable it in the phone’s settings.

Additional elements of RTT accessibility

The Federal Conversations Commission (FCC) promotes phone service providers to provide a greater variety of accessible phone communications. courtesy of miodrag ignjatovic/Getty According to the Federal Communications Commission, telephone makers and service providers should include different RTT accessibility features and capabilities into their products and make them broadly available to telephone customers by June 2021. There are several ways to improve user accessibility and experience, including offering accessible call indicators, which allow RTT callers to know whether they have reached a busy line or if the call has been answered without the need for an audible tone.

  • Color, size, and font may all be customized using the control options. Caller identification features, call transfers, teleconferencing, and interactive voice response systems are all employed. Improved compute rates to allow for simultaneous use with real-time phone conversations
  • Creating devices that come pre-installed with RTT functionalities activated by default, allowing users to access RTT quickly and easily

Implementing Real-Time Text

Using Real-Time Text (RTT) on Android 9, this post will show you how to build it. RTT is a function for deaf or hard-of-hearing users that takes the role of Text Telephone (TTY) technology in some situations. In addition, devices may utilize the same phone number for voice and RTT conversations, send text as it is being written on a character-by-character basis while concurrently transmitting it, allow 911 communications, and give backward compatibility with TTY with this functionality. Both the caller and the receiver are aware that they are participating in an RTT call when they make the call.

When typing, the text appears and is delivered in the order in which it is entered, letter by letter.

Examples and source

AOSP atCall includes framework components that may be used to build applications. RttCall and RttConnection are two different things. RttTextStream. These components are private to the IMS/modem provider and should be provided by the IMS/modem vendor. A reference implementation of the Dialer RTT protocol is also available. RTT dialer code from the AOSP:

  • AOSP atCall provides access to framework components. The call and connection RttCall and Connection RttCall and Connection RttTextStream. IMS/modem components are proprietary, and they should only be provided by the IMS/modem provider in order to function properly. A reference implementation of the Dialer RTT protocol is also available for downloading. For RTT, the following is the AOSP Dialer code:


It is necessary to collaborate with a modem/SoC supplier in order to deploy RTT since a modem that supports RTT is required. If you have an Android 8.0 device, you may either update to Android 9 or backport a list of telephony framework fixes to it. APIs included in Android 8.0 AOSP will not function properly. This functionality makes use of public APIs in the Android Open Source Project (AOSP) inandroid.telecom and @SystemApis inandroid.telephony.ims. The whole user interface is contained withincom.android.phone and the AOSP dialer.

This necessitates the following:

  • Turning RTT on and off viaImsConfig setProvisionedValue(RTT SETTING ENABLED)
  • Indicating the RTT state of a call viaImsStreamMediaProfile mRttMode
  • And indicating the RTT status of a call viaImsStreamMediaProfile mRttMode InImsCallSession, support is provided for the following methods:
  • The following commands: sendRttMessage
  • SendRttModifyRequest
  • SendRttModifyResponse
  • InImsCallSessionListener, support for calling the following methods is provided:
  • Several calls to callSessionRttModifyRequest were received, as well as calls to callSessionRttModifyResponse were received.


Using the device configuration,config support rtt, in the device configuration overlay forpackages/services/Telephony, and the carrier configuration flag,CarrierConfigManager.RTT SUPPORTED BOOL, in the carrier configuration files, you may activate or disable this capability. Depending on how the feature is configured, it may or may not be accessible through the Accessibility options. To alter the default settings, access the device configuration. By default, the function is turned off in the settings.


Run CTS tests as well as dialer RTT tests to ensure that your implementation of RTT is sound and reliable.

CTS testing

The AOSP component of the implementation is covered by the CTS tests (android.cts.telecom.RttOperationsTest) in the Android SDK. You are responsible for developing your own tests for the IMS stack element of the implementation.

Real Time Text

I’m using a Samsung Galaxy S20 smartphone. Real Time Text, or RTT for short, is a function that has been integrated in the program. This is not an application that I have downloaded, and there is no way to turn it off. It is designed to allow hearing challenged individuals to type or receive text messages while on the phone. It appears that this function has a mind of its own and will start up at random when you are on a voice call. When this occurs, the call is severely disrupted, and it is almost always necessary to end it.

  1. If someone responds with “Go into settings,” I will know right away that they have no concept what this feature is all about.
  2. Samsung, take the lead!
  3. There are numerous internet complaints from dissatisfied customers.
  4. I fixed it by downloading and installing the ACR Phone Dialer from the Google Play Store and setting it as the default dialer.

There will be no more RTT issues. [email protected] Are you using the default phone app or are you using a different one? I’m aware that Google gives instructions on how to turn it off for their phone application. Have you tried any of the standard troubleshooting procedures on this?

  • Completely update your device
  • Reboot the phone
  • Boot into Safe Mode
  • And repeat the procedure once again. If it works, you may need to uninstall any programs that you have recently installed. Then restart your computer to try again. Try clearing the device cache and doing this procedure once more. Repeat the process of resetting the device and then doing this procedure once more.

If any of the methods outlined above are helpful, please let us know below and mark this article as the answer. Also, do you know if the Samsung support team may be of use to you?

  • If such were the case, I would gladly uninstall it and would not be commenting on this forum.
  • This EMBEDDED feature is a component of the phone’s software and is not separate from it.
  • The only way to turn this off appears to be if Samsung releases an update that removes it from the system.
  • There is nothing in the options that would allow you to disable it.
  • I did not stress on the fact that this was an app or declare that it was.
  • Is it possible that you were experiencing this issue (not only the function) with the S10 as well, or simply the S20?
  • Are you utilizing the default phone app or one developed by a third-party developer?

If you work with us, we might be able to resolve this.

This happened to me on a Galaxy S10, and it’s happening again with a Galaxy S20.

It is a pre-installed feature.

I am unable to stop or remove it because it is not an application.

There are several erroneous postings on various search sites on how to switch off RTT.

If I knew how to fix this, my posts would not be appearing on this site.

I spent a full day talking to Tech Support from my carrier and putting the suggestions they gave me to work.

None of this resulted in anything other than me losing stuff I really wanted.

It worked!

I appreciate your comments, but if you are new with RTT and how it is integrated into the device, you should sit in front of one of the devices and see how it works.

According to other forums, if your caller has RTT turned on, you will immediately receive it (unconfirmed).

Recently, the default dialer on Verizon/Samsung got a UI hit, and it was a bad one.

I needed to get rid of it, and I eventually discovered ACR Phone Dialer on the Google Play Store, which worked perfectly: I would highly suggest it.

RTT has been referred to as an app by you and others, but this is plainly not the case.

I spent the better part of a day resetting different aspects of the S10.

During a call, a vertical elipse appears on the screen, and it looks that RTT is engaged as a result of the elipse appearing on the screen.

RTT is pre-installed.

Please accept my apologies if you believe I am being confrontational.

Do you use any form of external equipment, such as a headset or earphones, to listen to music?

@user4Gdqjep2wZ Have you looked in the Settings menu for “Real Time Text” and turned it off?

This has never been referred to as an application.

You may get to SetingsAccessibility by typing in the URL.

Do not hesitate to contact me if you have any additional questions or concerns.

Please follow the steps you just sent me on your Galaxy S20 to ensure a successful installation.

I’ll say it again: this is important.

It occurred to me that one of the “suggestions” was to boot the phone into Safe Mode (which is the same as Airplane Mode on the S20) and check whether the event occurred.

It is possible to make a phone call in this mode, but it is not possible to do so. The little vertical elipse that shows only when you are on the phone occurs only during a call. And just for the record, you inquired as to whether you were using the default phone app or one from another developer.

Real-Time Text

Real-Time Text (RTT) is text that is communicated as soon as it is written or produced, rather than after it has been saved. Characters written on the transmitting device are shown on the receiving device almost as fast as they are typed on the sending device. RTT is something that happens in a short period of time!

Real-Time Text Benefits

It is extremely beneficial for those who are deaf or hard of hearing, or who have a speech impediment, to use Real-Time Text. RTT is also effective in noisy surroundings or for providing complex information, such as addresses, to several recipients.

Key Features of RTT:

  • It eliminates the need to connect to TTY devices on the move. The app is compatible with both the Cricket cellular network and Wi-Fi Calling. When compared to TTY and relay services, it allows for a more natural conversation flow. RTT-to-RTT calls can be made with both text and speech being delivered at the same time.

How to Setup Real-Time Text

  1. Activate the Phone application on your smartphone. Select the More icon, followed by Settings. Text Telephone mode may be activated by selecting Accessibility, then TTYmode. If you see Real-Time Text, make sure it is turned on.


  1. Navigate to the Settings menu. RTT/TTY may be enabled by selecting Accessibility > RTT/TTY > Software RTT/TTY > Relay Number > Enter a phone number for TTY relay calls > Save

What is RTT? How do I turn off RTT on Android? Step By Step Guide

RTT (Real-Time Transport) is discussed in detail in this article, as well as how to disable RTT on Android. In real-time texting, this technology allows wireless phones connected to IP-based networks to send text messages as soon as they are generated, a process known as real-time texting (RTT). RTT eliminates the need to hit the “send” key, which is required for sending SMS, chat, or other types of communications through the internet.

What is RTT on my phone?

It is possible to send and receive text messages while having a phone call using real-time text. RTT may be utilized in combination with TTY without the need for any extra equipment.

This article may not apply to all types of gadgets, and the information included within it is subject to change without notice. Inquire with your carrier to see whether or not RTT is compatible with your device and service plan.

What is Samsung’s real-time text feature?

This article contains information about the RTT implementation in Android 9. For those who are deaf or hard of hearing, RTT technology takes the role of Text Telephone (TTY) technology. Using the same phone number, users may make both voice and RTT calls, send text that is character-by-character as they type, enable 911 communications, and use TTY backward compatibility, among other features. When they are conversing, both the caller and the receiver are aware that they are participating in an RTT call.

Text displays and is transferred character-by-character as it is input into the computer system.


RTT deployment necessitates the use of modem/SoC providers, since a modem capable of supporting RTT is required. To deal around this issue, you may backport a number of Telephony Framework changes into Android 8.0, or you can upgrade to Android 9. There will be difficulties with APIs that were introduced in the AOSP release of Android 8.0, according to Google.

  • This capability takes use of the @SystemApis annotation in android.telephony.ims and the public APIs in android.telecom in the Android Open Source Project (AOSP). The AOSP dialer and the com.android.phone package are in charge of all UI
  • The AOSP code should be imported, and an IMS stack should be provided that implements the RTT @SystemApis on the IMS side of things. This implies the following: RTT may be enabled or disabled using ImsConfig setProvisionedValue(RTT SETTING ENABLED)
  • ImsStreamMediaProfile mRttMode is used to indicate the RTT state of a call

ImsCallSession supports the following methods in addition to others:

  • SendRttMessage
  • ssendRttModifyRequest
  • ssendRttModifyResponse

The ImsCallSessionListener class provides functionality for invoking the methods listed below:

  • Call to SessionRttModifyRequestReceived

Real-time text – Wikipedia

Real-time text (RTT) is text that is communicated immediately after it has been written or produced. The message may be seen directly by the recipients while it is being typed, so they do not have to wait. Real-time text is used for a variety of purposes, including conversational text, collaboration, and live captioning. TDD/TTY devices for the deaf, live captioning for television, Text over IP (ToIP), some types of instant messaging, captioning for telephone / video teleconferencing, telecommunications relay services including IP-relay, transcription services including Remote CART, TypeWell, collaborative text editing, streaming text applications, and next-generation 9-1-1 /1-1-2 emergency service are examples of technologies.

TDD/TTY devices are being phased out in favor of more current real-time text technologies such as Text over IP, ip-relay, and instant messaging, which are replacing obsolete TDD/TTY devices.

During 2012, the Real-Time Text Taskforce (R3TF) developed a standard worldwide symbol to symbolize real-time text, as well as an other term for the technology called Fast Text, in order to promote public education about the technology and its benefits.

Use over instant messaging

While normal instant messaging does not support real-time text (the message is only delivered at the conclusion of a thought, not while it is being produced), certain instant messaging software does support real-time text, such as AOL Instant Messenger’s “Real-Time IM”feature. With the usage of proper software that has a real-time text capability, real-time text may be transmitted via anyXMPP-compatible chat network such as those used byApple iChat, Cisco WebEx, and Google Talk, among others.

Real-time text programs have been around at least since the 1970s, when the DECPDP-11 introduced thetalkprogram, which is still in use on Unix systems today.

This enables the sender to construct the message as if it were a conventional instant message or text message before sending it.

Use by the deaf

A variety of real-time text services, such as IP-Relayservices, TDD/TTY devices, and Text over IP are popular among the deaf. Real-time text allows the other person to read what is being delivered instantly, rather than having to wait for the sender to finish drafting his or her sentence/message before starting to read. This enables for the use of text in conversational situations, much to how a hearing person can listen to someone talk in real time.

Captioned telephony

It is the streaming of real-time text captions in tandem with speech over a phone conversation that is known as captioned telephony. Those who are hard of hearing can benefit from this by listening as intently as they can, picking up on all of the intonation and other subtleties of speech, while also having subtitles for the words that they cannot hear well enough. captioned telephony is one of the free relay services provided to those who are hard of hearing in the United States, and it is available to anybody who has a hearing loss.

Use in collaboration

Collaborative real-time editing is the use of real-time text for shared editing rather than for chat, and it is becoming increasingly popular. It is also termed real-time text when the conversational text displays in a split-screen format that is continually shown. For example, Apache Wave and its derivative SwellRT, Etherpad, the editor Gobby, and most famously, Google Docs are all instances of applications that deliver this as a service.

Captioning, transcriptions and other uses

Real-time text is utilized in closed captioning as well as when captions are transmitted live and constantly during live events, such as sporting events. Transcription services, including Communication Access are available. Translation and typing in real time When we talk about real-time text, we’re talking about text that is broadcast live to a distant display.

This is utilized in court reporting, and it is also used by deaf participants at conferences to communicate their needs. Additionally, real-time texting gives an addition to text messaging on mobile phones through the use of real-time texting applications.

Real-time text protocols

Text over IP (ToIP), which is based on ITU-TT.140, IET-FRFC 4103, RFC 5194, and the XMPP Extension Protocol XEP-0301, are examples of real-time text protocols.

Total conversation

Total conversation, according to ITU-T Multimedia Recommendation F.703, is defined as the simultaneous use of voice, video, and real-time text in a discussion. Compliance would be achieved by using an instant messaging tool that can activate all three functions at the same time. Real-time text is a critical component of this system.


Real-time text may also be found in previous versions of UNIXtalk, BBS software such asCelerity BBS, and older versions of the ICQmessaging program, among other places.

AT&T Real-Time Text (RTT)

  • TTY capabilities may impose restrictions on RTT to TTY and TTY to RTT conversations, among other things. A one-way communication channel must be maintained during the dialogue between RTT and TTY users until the individual has finished speaking. The other individual can then answer by text message. Text messages can only contain characters that are compatible with the TTY. If you are using other softphone programs (for example, FaceTime ® and Skype ®) at the same time as your RTT device, you may experience difficulties receiving calls. The software runs best on tablets that are equipped with 4G and 5G networks. The usefulness of the 3G network is restricted. When you use a device that is not AT T-certified, or when you use a network other than ours (for example, Wi-Fi ®), the quality of your service may be affected. Devices that are on suspended accounts behave in the same way as devices that have been deactivated or disabled. Those devices will only be allowed to make voice 911 calls and will not be able to make RTT calls until the account has been renewed. Using our new 2-step sign-in procedure, we can help keep your information secure. Find out how to set it up and how to use it.

Answer or make RTT or TTY calls from your iPhone

Using iOS 10 or later on your iPhone, as well as a cellular connection, you may make RTT or TTY (Real-time text/Text Telephone) calls without the need for any additional gear. You may also see transcripts of earlier phone conversations. This feature is only available for plans from carriers in the United States and Canada. It is not accessible for international plans. Both Software and Hardware RTT/TTY calls are subject to the same standard voice call fees. RTT, TTY, or RTT/TTY are all possible options depending on your provider.

Set up RTT/TTY

  1. Navigate to the AccessibilityRTT/TTY section of the Settings menu. Activate the Software RTT/TTY or the Hardware TTY. Tap Relay Number and type in a phone number for RTT/TTY relay calls
  2. Then tap Save. If you wish to transmit characters as you type them, select Send Characters Immediately from the Send Characters menu. Alternatively, you may switch off Send Immediately to enter complete messages before sending them. To answer every call as RTT/TTY, select Answer All Calls as RTT/TTY from the drop-down menu. Turn on Hardware TTY if you wish to answer and make RTT/TTY calls from an external RTT/TTY device rather than from your iPhone.

In the event that you enable Answer All Calls as RTT/TTY, you will no longer receive voice calls.

Is there a way to turn off the real-time text (RTT) answer option for incoming calls?

  1. I understand that this wasn’t always the case. In the line of options that appears when I get an incoming call, the option “Answer as RTT call” is now the first option that appears. Then there’s “screen call,” and so on. Is there a way to turn this feature off completely? This is not enabled in my options, as far as I can see. I’ll throw in this intriguing fact: I happen to deal with Deaf individuals and am proficient in American Sign Language (ASL). According to this, Google is surreptitiously recording you in the most extreme manner possible. Google determined that this was significant to me, and as a result, it requires that I have the choice easily available to me. Was it there, or wasn’t it? Do you have it with you? 05:51 p.m. on December 21st, 2019
  2. If the caller has RTT enabled, the RTT option is activated as well. That is something you cannot “defeat.” Originally posted byRukbat on December 21, 2019 at 5:18 p.m. If the caller has RTT enabled, the RTT option is activated as well. That is something you cannot “defeat.” That makes perfect sense. It doesn’t seem to make any sense to have this enabled by default, to be honest. I ran the test with two iPhones phoning me at the same time. I have to presume that neither hearing user (even one whose wife is Deaf) was aware of the existence of RTT, and that they did not activate it (or off). RTT has piqued my interest, and I’d like to learn more. I did give it a go. I’m not aware of any of my Deaf friends or coworkers who make use of it. We communicate by text message (they iMessage). Facetime. It’s possible that it’s a hearing person thing. Excellent. 12-21-2019 06:05 PM
  3. Excellent. We now understand what it is. What can I do to prevent it from appearing when a call is received on my phone? It’s something I don’t want to see. The other two selections are more essential to me, therefore I’m going to have to scroll over and send a text in response to them. Absurd. People who do bad design work. Please provide us access to our phones’ configuration options. RomeoAlphaBravo posted an original message on 12/23/2019 08:45 PM. Great. We now understand what it is. What can I do to prevent it from appearing when a call is received on my phone? It’s something I don’t want to see. The other two selections are more essential to me, therefore I’m going to have to scroll over and send a text in response to them. Absurd. People who do bad design work. Please provide us access to our phones’ configuration options. Please see the following page for assistance:. The issue, as Rukbat pointed out, has to do with the caller’s RTT setting rather than yours. If you had the capacity to reject or deny an RTT call, you would be interfering with the ability of a hearing-impaired individual to speak with you on a regular basis. In what way that choice is a burden on the user, I’m not sure I understand. Swiping up on a phone is the standard method of answering a call. The RTT call button would have to be deliberately tapped in order to be answered as an RTT call. Presumably, if you are aware that the individual is deaf or hard of hearing, you would do something similar in order to communicate successfully. EDIT: After re-reading the response, it appears that the problem is caused by the need to scroll over to react with text. However, because RTT is essentially a text-based call, you may use it in place of a text message if you like. 12:00:54 p.m. on December 23rd, 2019
  4. I’ll go through the source of my aggravation one more time. When a call comes in, I now have three options shown on my computer screen. RTT, screen, and text response are all possible. I utilize respond with text on a regular basis. For me, the RTT is both an inconvenience and an obstacle to readily accessing a function that is considerably more vital than it appears to be. I should be allowed to pick which of these I wish to view, and if I’m forced to see them all, at the very least enable me to select the order in which they appear. It is my hope that this has made greater sense to you. This is not a retaliation against those who must communicate over RTT. I just feel that, because it is my phone, I should be allowed to choose which features to display and which ones not to display depending on my own preferences. Some people may think you’re insane, but I’m not.:-) 24th of December, 11:55 a.m. I also appreciate the ability to send SMS messages quickly. I don’t want to have to answer the phone and then talk into the phone, just to have it translated into text. Keep things as basic as possible. 24th of December, 11:55 a.m. Okay, I get what you’re trying to express. The best thing I can recommend is that you provide comments to Google about it, and possibly propose that the alternatives be rearranged in the order in which they appear. I’m simply interested if you see the RTT option show regularly or if it only appears every once in a while. 24th of December, 2019 at 1:20 p.m. The difficulty with turning on rtt is that it makes it difficult to navigate numerous touchtone menus, which are used by many major firms these days, not just banks, to accept calls. As a result, unless a live person replies, one is out of luck. If Android is going to force this on users, it should provide a floating button that allows them to turn it off. 03-17-2020 02:03 PM

  6. Dear all those who are suffering with RTT- Google help is completely ineffective, as they have locked all posts on RTT. Samsung’s customer service department does not even understand the menus on its phones. According to this topic and other sites, if your caller has RTT turned on, you will immediately get it when they call (unconfirmed). The RTT function on my Galaxy S10+ does not have an off button. Recently, the default dialer on Verizon/Samsung got a UI hit, and it was a bad one. I installed the Google dialer, and while the user interface was improved, RTT was present on every call. I needed to get rid of it, and after after searching, I discoveredACR Phone Dialerin the Google Play Store. I would highly suggest it. 08:20 p.m. on June 18, 2021

2019 Sprint Real-Time Text Talking Points

Q. What is Real-Time Text (RTT) and how does it work? 1. RTT is an IP-based technique that allows users to send messages character-by-character as they are being entered into a computer. Essentially, this implies that the receiver may view the freshly formed content while the sender continues to type it. Individuals who have a hearing or speech handicap and have been utilizing obsolete TTY technology will find RTT to be very beneficial. Sprint will begin its transition to RTT when it implements IP-based calling technologies, such as Voice over LTE (VoLTE), and as it expands its network coverage.

  1. What is the significance of RTT?
  2. In an attempt to ensure that persons with hearing or speech disabilities continue to be served, the Federal Communications Commission (FCC) has mandated that cellular carriers employ RTT to ensure that their requirements are addressed as technology evolves.
  3. Q.
  4. In addition to continuing our VoLTE rollout and testing in several locations around the United States, Sprint is now enabling RTT capability in those markets.
  5. The RTT standard will be expanded to include other devices in the near future.
  6. Does Sprint still provide TTY service?
  7. As a result, Sprint’s support for TTY over its CDMA network will remain even after the company’s countrywide deployment of VoLTE is completed.

In order to ensure that persons with hearing or speech disabilities continue to get dependable service in the future, Sprint is dedicated to ensuring that they do so in the present. In addition, please see the following information.

Q. What is Real-Time Text (RTT) and how does it differ from other text messaging services? 1. RTT is an IP-based technology that allows users to transmit messages character-by-character as they are entered in real time. 2. Essentially, this implies that the receiver may view the freshly formed content while the sender continues to type it. For persons who have a hearing or speech handicap and have been reliant on obsolete TTY equipment, RTT is particularly advantageous. Sprint will begin its move to RTT when it implements IP-based calling technologies, most notably Voice over LTE (VoLTE).

  • Notice to Customers Concerning RTT and Voice over Wi-Fi:

Sprint’s network allows RTT calling over Wi-Fi as long as the customer’s device has been correctly setup to use Sprint’s RTT and VoWiFi Calling services, which is currently the case. The quality of a VoWiFi call might vary depending on the strength of the wireless signal, the performance of the network, and the internet service provider through which the call is routed. It is possible that technical difficulties will delay or prevent the reliable and correct delivery of TTY messages via IP-based networks, such as Sprint’s voice over Wi-Fi (VoWiFi) technology.

It is possible that a user will disable the VoWiFi feature on their Sprint phone if they enable the TTY calling capability.

Customers are encouraged to investigate alternate modes of communication if a CDMA signal is not available.

Using any of these Relay services, you can dial 911 for assistance in an emergency. Finally, clients have the option of sending a text message straight to 911. (where text-to-911 is available). RTT Consumer Guide from the FCC:

Easier phone calls without voice or hearing

In order for the phone to listen and speak on the users’ behalf as they type, Live Relay makes use of on-device voice recognition and text-to-speech conversion. Smart Reply and Smart Compose, which provide rapid replies and predictive writing ideas, make it possible to type quickly enough to participate in a synchronous phone chat. Live Relay is totally contained within the device, ensuring that calls remain private. Because Live Relay communicates with the other party over a standard phone conversation (no data connection is necessary), the other party can even be a landline phone.

In the United States, for example, services such as relay and real-time text (RTT) are provided to those who are deaf or hard of hearing.

Instead, we intend to supplement them with Live Relay as an extra choice for the scenarios in which it can be most useful, such as when dealing with an incoming call or when the user chooses a totally automated system out of concern for their personal information privacy.

How many times have you received an essential call but were unable to take a break to talk with the person on the other end?

We are also looking at the possibility of integrating real-time translation capabilities, which would allow you to possibly call anyone in the globe and converse with them regardless of their language hurdles.

Although Live Relay is currently in the research stage, we are looking forward to the day when it will be able to provide our users with new and better methods to communicate—particularly for those who may be neglected by the current alternatives.
