I actually like using the physical keyboard versus using the virtual one, but I find myself using the virtual keyboard more often for one simple reason:
(For Texting) As I'm typing a word, it tries to predict the word I'm typing, or will give me a suggested word for what I've typed if I have a typo in it. When I use the physical keyboard this option is not available.
I've looked in the settings to see if the feature was turned off for the physical keyboard, but did not find anything. Any help would be appreciated.
