I don't use the Samsung messaging app because of some of the feature I have mentioned below
1. To archieve specific contacts
2. To group by known senders, also an option to show this group at launch
3. To block the conversation (not just the messages having phone number, but every conv including promotion, spam messages)
4. Spam filter like in Google messaging app and also an option to turn off notifications for spam messages
5. No Notification and no sound(option) for request message received feature
For now this is all I can remember.
I am currently using Google messaging because of blocking and span filter feature and archiving conversation. But I don't like the that material themes. I want complete dark themed what's the use of Amoled if it is doesn't have dark theme.
