Have a look at this guide Guide: Text Message Tips (not sent or received) 

Change the messaging app back to the Samsung /Google App as well.

Have you done a full factory reset on the device, making sure you have backed all the data, before resetting the phone.

It might also be worth speaking to Samsung direct.
