Re: how do i add words to my library when i am texting
As Paul said it depends on the keyboard. But most of them use a similar way to do that. When you write a word that is not in the dictionary it will be underlined in red. Tap on it (maybe you'll need to long press) and a menu wil pop up where you can add it to the dictionary. You don't need to add the word right after writting it, you can always come back to it after you finished your text.
To add words try to tap letter by letter instead of swipe. It will be much easier.
