I read that Smart Keyboard Pro does predictive text with hardware/device keyboards. I played with many options, including hiding the on-screen keyboard. However, the on-screen keyboard still pops up when I tap an input field. After I close the on-screen keyboard with a swipe down or back button, then I can use the device keyboard with predictive text. Please have an option to always hide the on-screen keyboard but continue to allow predictive text.
Also, the Samsung Galaxy Pro has arrow buttons. Is there a way to select from the predictive text results using them?
