Look for the gear icon on the home screen or in the app drawer. Use this method if you have a Samsung phone or tablet and haven’t installed a different keyboard. Depending on your model, you may have to tap General or General management to find this option. It’s under the ″Keyboards and input methods″ header. It’s usually under the ″Smart typing″ header. If the keyboard has been keeping track of what you type to make predictive recommendations, the switch should already be set to ″On.″ If the switch is in the Off/gray position, there’s no keyboard history to delete. The name of this option varies by model, but you’ll find it near the bottom of the menu. This removes all of the words saved by your keyboard. If you want to delete all of your keyboard’s settings, including dictionaries, layouts, and languages, see the Clearing All Android Keyboard Data method.
