Go to Messages -> Theee dots in corner -> Settings -> Chat Settings -> Default Message Type -> Automatic
Just worked for me
Mine is already set to Automatic and it doesn't fix the issue. Samsung, get this fixed or let me delete the Samsung apps.
The same thing is happening on the new S10 Plus unlocked. It's compressing the gif way too much and not one solution on this post has worked on my phone. Guess i'll be switching back to the android messenger.... Thank you samsung
