How to fix 'Can’t send GIF image' error pop-up on messages app

AGIF(animated GIF) image files can be shared with others by using the GIF keyboard on the Messages app. But total attachment size of MMS has limitations and it should not be over max size. (300KB~1MB, Max size may vary depending on the region or service provider)

When you attach the AGIF file via the Messages app, the application compress automatically the file however you cannot send the selected AGIF image files to others if the compressed AGIF size is over the max size defined by region or service provider.

This popup window is normal operation and we recommend to use another image.
