Heyo, just noticed something big beta 4 has added, suggested replies/ai chat reply.
It was originally in beta 1 as a labs feature, I think it got removed in beta 3. Seems it's back. On opening certain apps, the predictive text above the keyboard becomes ai generated replies.
In the previous beta, it appeared on the screen/app itself and sorta got in the way. Seems they integrated it into the keyboard. Unsure of which apps are currently supported.
Also be aware, technically this means all your full conversations are now being sent to samsung ai for processing. You can enable on device mode if this is a privacy convern. This is also only enabled if you turn writing assistant, suggested replies on.
