How to use smilies when texting in mobile

Based on your description, what you are referring to is called T9 Predictive Texting. It allows words to be entered by a single keypress for each letter, as opposed to the multi-tap approach used in the older generation of mobile phones in which several letters are associated with each key, and selecting one letter often requires multiple keypresses. Example, when typing the word 'love' in a T9 activated phone, all you have to do is press the numbers 5, 6, 8 and 3 once in sequence. As compared to the regular texting, in order to complete the word 'love', you have to press the number 5 thrice, the number 6 thrice, the number 8 thrice, and the number 3 twice.
If you want to disable T9 predictive texting, it can usually be disabled by pressing and holding the hash or number key (#).
Hope this information is helpful.

You must disable your Predictive text option, T9® predictive text mode allows you to type words with only one keystroke per letter, and the phone interprets what word you want. For example, to type the, press 8, 4, 3. To enable/disable T9® predictive text mode, select Options. Scroll to and select Prediction on or off.

it is the same key as to change case. If you press it repeatedly, it'll cycle through various options in the top right of the screen:
initial caps with predictive,
all caps predictive,
lower case predictive,
numbers,
initial caps without predictive,
all caps without predictive,
lower case without predictive.

When T9 is not displayed, predictive text is off.

Just to spice things up, Samsung's idiotic software designers made it so that depending on the situation you're inputting text, the order that things cycle through is different, so you can't just press it a certain number of times to turn it off, you have to pay attention to the icon in the top right.
