Hello everybody I am owner of Nokia. Lumia 620. I am satisfied with phone but... there are always but I am really disappointed with keyboard, there's no full screen keyboard :/ in landscape mode is almost the same size like in portrait mode.
Welcome aboard to WP central, it's great to have you here. Please look around the forums you're fine many answers to your questions. I also had a rough time with the keyboard but now it's great after getting use to it.
