Word flow has never worked for me. Ive done multiple hard and soft resets to no avail. If i have suggestions on the keyboard freezes after i hit space. I have to disable everything just so i can type anything. I had a 920 with dev preview and i just thought it was something i had to deal with then I just upgraded to a new 1520 and the poblem followed me to the new phone. I gave the 920 to my son and after a reset everything works fine for him. Any help would be greatly appreciated!
