I've only had the Evo 3D for maybe a week and I've noticed now when I'm entering text in and I tap the space bar to separate words the text just entered disappears. The keyboard also disappears and when I attempt to get the keyboard back onto the screen, the screen will flash as if the keyboard was going to appear but nothing. The only way to temporarily stop this is to turn off the phone and then turn it back on and after a few successful texts it does it again. Also I noticed that this problem started after the last of the updates. Has anyone else had this issue?
I am sorry you are having this problem. Which keyboard are you using...the HTC touch keyboard or the Swype keyboard? Can you try to remove/replace the battery to see if it will work right once the phone has restarted?
It only does this when using the Swype keyboard. I took it in to a Sprint Store and they were unable to help since it does not happen all of the time.
after doing the battery pull. if it happens again try long pressing in the text box. chose input method and switch it to whatever youre NOT using (swype,touch) then repeat that again but switch it back to whatever input method you were using and it should work fine. its a weird hiccup in the system that has yet to be figired out or repeated on demand
