A brand text me everyday.

How can I block it?

In the phone number area only brand name is visible. (Phone number is not visible.)

Tap the profile picture -- do you get an option to block there?

[zanshin777]

Profile Picture is unclickable.

(Although Normally a profile is clickable.)

One option is Google message app has option to report as spam

[B. Diddy]

What about long-pressing the message thread in the main message thread list?

What about long-pressing the message thread in the main message thread list?

Then It selects the message. There is only option after selecting it which is "delete".

It looks like It's not possible without a 3rd party app.

Open one of those spam message thread and show us a screenshot. Do you get any options if you tap the Menu button when you're in the message thread?
