Hello!
I have a Samsung Note 8 and I had the same problem, but I fixed it. I am not sure if the set up works the same for all Galaxy Note cellphones.
Here's what I did;
° Go to your Messages Settings.
° Under Settings <--> Chat Settings
° Chat Setting <--> Image Size
° Under Image Size you'll have five (5) selections.
1. Best available
2. Original
3. Large (50%)
4. Medium (20%)
5. Small (10%)
I picked Original. But you can choose the sizes of your choice.
Under "Multimedia Limit" you'll have 2 choices.
1. Automatically accept all
2. Automatically accept files less than 9765 MB in size.
I chose "Automatically accept all"
Good luck!
Marie
