I had the automatic dictionary prediction setting in my Samsung Wave mobile phone. There are kids in the house and it got deactivated at some point ...

It was a real pain to figure out how to enable Dictionary Setting back on my Samsung Mobile Phone. I then figured it out after a long time. This setting must be the same on all Samsung Devices (Ipad or any other Samsung Mobile phone).

Open the Keypad and you should see a button at the bottom most row with a globe sign on it and text "EN" beside it as seen in the snapshot below (Red circled button).



Press on the button shown above and you should see the setting "Predictive Text" as seen below. Enable it to enable dictionary or auto predictive text mode. Disable it to disable dictionary setting. Pretty Simple once you know this
