I know this is just picky, but my Samsung Messages app shows a callback (CB# xxxxxxxxxx) every time it receives an SMS message. I know it doesn't affect functionality, but it's like a little itch in my brain that I can't scratch when I see it. The Callback number setting turned to Off apparently only blocks my phone from sending a callback number, not the other way around. I've been using Textra which works without the CB#, but I really like the stock Messages app, and would prefer to use it. Is there any way to turn this off (so that it doesn't show a CB# with every text message)?
