[AC Question]

How can I block text messages from a particular number on my Samsung Galaxy prime. I have add the number to my auto reject list , but still receives text from the number.

The reject list for the phones calls is separate from the reject list or texting.
In your SMS app verify the number is in that app's reject list.

This will not prevent the phone from receiving text messages. What it will do is either (1) receive and delete the message, or (2) receive and store the message without given a notification. Which one will depend on the app.

Which SMS app are you using?

Add the number to your contacts, open contacts... Find the number... Tap the three dots on top right corner... Tap block number....
