I guess this is really a rather trivial issue, but when I am phoning and the screen darkens, the phone of course hides the keyboard screen to avoid my pressing keys with my ear while phoning. When the call terminated, in the past the keyboard or previous screen re-appeared, but for the last week or so it's been necessary that I press the home button to reactivate the keyboard and end the call. I'm just curious since I haven't found a setting and would like to know how to handle the option.
