Laban SMS Customer Insights

1. Keyword based blocking doesn't work most of the time.Greatest app i like it, it hide message content at notification bar, and it has a private box which means a code can be set for personal msg, this app is v good, one thing to be improved that it show nmbr with contact name, only name should be exist in chat memu for better safety...Spam blocking is excellent, but I was not receiving any of my group MMS.

2. Hopefully the dev would add dark mode.If the colour of each conversation can be fixed as the default background colour, it is more perfect.Good.. it change the default messaging app and available option to send message by sim 1 or sim 2 (i use 2 simcard)This app replaces itself to my default sms manager.

3. Option to change colour of individual sender messages doesn't always work for some reason.Most of the spam messages in my inbox don't even show up when i try to add a blocking rule from messages.

4. No option to change the background to a dark one and no system wide option to change message colour which has made most of mine unreadable.

5. I want to usd it as a blocker not sms program.Blocking the number from an area code doesn't work.

6. Seemed promising but doesn't work properly with Samsung dark/night mode in earlier versions of Android.

7. more I suggest if you make it to popup the message and to show new message on the app.A great and simple app to block sms based on keywords.

8. I can't continue to use due to this.It is good app.

9. Although it says so in the app description.

10. I liked it.
