T9 (Text on 9 keys) was introduced in 1999. Since then, this feature can be found on almost every mobile phone. Android phones also feature a similar auto-correction feature. This can be annoying for some users. To disable this feature:
- From the Home-screen, press Menu button > Settings
- Go to the My Device tab and scroll to Language and input.
- Tap on Samsung Keyboard.
- Turn off "Predictive Text"
