[Android Central Question]

It only happens with one specific caller. It's never happened before today. It is a set of black hash lines and a capital T. When they try to call me they can hear me but I cannot hear them

I have a strange symbol next to 1 of my contacts. When they call me I can't hear them but they can hear me. Its its several hash Mark's and a capital T in black to the right of there name. If I can figure out how to post a picture I will. Galaxy s10+.

I don't know if this is Samsung or an app installed. Never seen it before?

[B. Diddy]

Could it be TTY calling? (Or RTT, Real Time Text?)

[Javier P]

Are you on T-Mobile? Maybe some carrier related feature like WiFi calling or similar?

[B. Diddy]

Found it -- it's Real Time Text: The International Symbol Of Real-Time Text | Real-Time Text

Here's a help page from Verizon: http://www.verizonwireless.com/suppo...e-base-227245/

Yes this can be turned off in dialer app settings

So, what's the use case for RTT exactly? I saw this first on the Note 9 last year. I understand you can see text as it's being typed, while you're on a call. Other than seeing the other person's typos in real time, how is this different from just sending an SMS?

[Rukbat]

SMSs are limited to 140 octets (160 ASCII characters or 80 Unicode characters). Anything longer has to be sent as an MMS or as individual 140 octet SMS messages. RTT is sent as you type it - no chopping it up or depending on the carrier's MMS server. It's probably going to become part of RCS.

It's a symbol on my call log next to an incoming call. It has 4 horizontal lines and a T.

the one I saw that looked useful (cool even) was when it was used in conjunction with video. so let's say you're in the library or cafe or someplace where you'd rather not talk out loud, rather than watch the person type their responses and wait till they hit send you can read what they're writing as they write it.

Nope, it's not carrier related. I have unlocked note 10+ and I use it on Verizon.

Have you seen B. Diddy's comment above?

Yes, I did see it if you must know!
Are we not here to help each other???
Excuse me for letting the person know it's not carrier related!

Yes, we are here to help each other and we try different things until we find the right one. As posted above B. Diddy found the right answer and other members agreed with that. Many times we'll try different approaches until the right fix is found, that's how a forum works. There's no need to go back to previous posts after this.

This is the reason I asked you if you have seen that particular post since mine was obviously the wrong approach to the problem.

It is carrier related my Att unlocked dont have it ...for RTT

[msm0511]

I know in the unlocked version you can go into the dialer settings and turn off persistent RTT as @mustang7757 said. I've never used it though.

BTW stang, clean out your inbox. Replied to your message. LOL

Ikr? He's the sole reason why the Samsung pre-order thread looks like that. I tried to message him about the Stang, but it was full. I posted it, then chaos ensued. Open season on derailing the thread. 😂😂😂
