If you're referring to the updated Samsung keyboard, I agree: there are plenty of features that are easily accessible. However, I've used SwiftKey (as have millions of other people) for years and their keyboard is just as feature-packed as Samsung's. The added benefit is being able to theme the keyboard (I prefer the Neon theme). But right now there's a contentious conversation in the SwiftKey Support Forum over their decision to make the default emoji tab the 'crystal ball' predictions, based on what emojis generally follow the last words entered. We are absolutely flame-spraying SwitfKey over this, and demanding the option to make RECENT emojis the default. Why should we have to sort through SwiftKey's best guess of what emoji we want to use when they're right there in Recents? I understand that an update allowing just that is forthcoming. It had better be soon.
In the interim, I used the Samsung keyboard as an alternative, in case I had to make good on my threat to uninstall SwiftKey if the update didn't roll out by the end of April. It's okay... but it's not SwiftKey. I hope Samsung enables keyboard theming very soon: if that happens, it'll be a force to be reckoned with!
