What features do you lose with the stock keyboard if you use swiftkey? I love swiftkey.
First, I'll say Swiftkey is amazing. Coming from iOS, then using the stock keyboard for a few days, Swiftkey is on a whole other level.
The one thing you lose from the stock if you go with Swiftkey is a 4th row for numbers. Apparently that's an upcoming feature for Swift, so it's no big deal.
The upsides are huge. Yes, the stock keyboard learns, but Swiftkey started auto predicting almost whole sentences within the same day. The stock keyboard was in no way doing that. All Swift key had to do was scan my SMS messages. It's also NATIVELY multi-language. No need AT ALL to switch between, say, English and Portuguese keyboard sets. There's no globe icon, it's just integrated.
I start typing in portuguese, it just knows and completes sentences in that language. I can literally write 1 sentence in portuguese, the next in english, then back to portuguese, all in the same SMS, and the keyboard swaps between both automatically. If you're not a multilingual user, you have absolutely no idea how incredible this is.
Swift key all the way. Best purchase so far on my note 3
