Steps to reproduce the bug

The text that should have been blocked was a political text. The keyword that should have been blocked was "stop=end". I suspect the message got through because it was sent with an image.

Testing with friends revealed that:
-The original text only contents of the political text were blocked when sent by a friend.
-The SMS character limit is not a factor, the keyword was blocked when at the beginning of a short text and at the end of a long text.

Unfortunately, I forgot to ask them to send the text with an image, so I haven't tested MMS (and I'm a little hesitant to keep bothering my friends with this). Steps to reproduce are most likely:

1. Set a keyword to block (in this case "stop=end")
2. Have another party send an MMS with an image and the keyword
3. MMS should still be delivered with a text that should have been blocked.

Expected behavior

Expected behavior is that any text message, SMS or MMS, image or not, should be blocked if it contains a keyword.
(As a side note, it would be nice to have the option to allow texts that do contain keywords through if they are sent by someone in your contacts).

Actual behavior

A text message with a blocked keyword was received.

Screenshots/Screen recordings

@CaseOf are you saying MMS from blocked phone numbers is not blocked?

on sms, I’m still getting notifications, but when opening the app, the message disappear.

I understand this is a feature request, so it should probably get its own post, but would it be possible to allow your contacts to act as a whitelist? That way in case someone I know sends me a blocked keyword I can still see it.

You can create a new feature request for this.

I also have been getting this bug. I installed this messages app instead of my phone default because of the keyword blocking, but I constantly still get political messages like this despite them containing keywords that I have blocked. Also, I don't know how to check whether some are getting successfully blocked or not because I don't believe there is any indication in the app if I would have received a message but it was blocked.
