I vote for remove all!   Let's go back to the tried and true smiley set.  What's this Twitter stuff about anyways?  Isn't that for teenagers and Presidents?  It was working so good before!  Actually even on my Xiaomi Mi A1 there's some lag, and I think it's a pretty snappy Snapdragon processor.  I like smilies, but sometimes too much of a good thing is bad!
