Most people can confirm that they have, at one point or the other, sent funny messages to friends. This is courtesy of the auto-correction feature that Nokia Lumia smartphones have. To avoid such messes, you can simply deactivate the auto-correction features.
In your Nokia Lumia smartphone, you will have to go to the settings. Tap on ‘Keyboard’ in order to display ‘typing settings’. Once there, you should tap on ‘Press To Change’ option usually located at the top of your screen. It is here that you will find a ticked ‘Correct Misspelt words’ option. Tap on it to remove the tick, and that’s it.
