When you type something on android keyboard then android system automatically saved the entered text word for suggesting these words next time when you just begin with few character.
You can do with setting to enable or disable auto saving feature but how you will delete a particular word?
Here is the image of suggesting the words when i start typing the “an” keyword
I need to delete the “anwered” from the suggestion
So hold your finger on “anwered” from some seconds automatically a popup will appear with Remove confirmation and you click the ok button to remove the keyword from already saved words that you entered.
