I have the same problem! So frustrating. Did you get an answer to this? Ives scrolled through replies and tried a few but nothing for me alot doesn't apply ... I have Samsung s7!x
It seems to be an issue with the stock Samsung keyboard. Do you have the Samsung Neural keyboard as one of your keyboard options?
If not, download Gboard. It's really good
I have a s7 running oreo using the stock Samsung keyboard version 184.108.40.206 (says it's up to date). And there is not an option to search for gifs, only able to scroll thru categories .
Many of the above suggestions about the smiley face aren't using the stock samsung keyboard.
If anyone has found a solution I'd love to hear it. I have used gboard in the past, I like it. But if I can use stock apps then that's memory I save.
Lol.. solution is overdue, but I read this thread hoping to find something-found nothing here, and starting pressing buttons..then.. shazzam!
First, pull up a message thread..
