One of my biggest pet peeves is that my phone auto-corrects the F-word to “duck. If it happens to annoy the sh*t out of you too, here’s how to fix it.
There are two ways: You can enter the F-word as a contact in your address book (make sure you enter effing eff to cover the action too).
Or go into your keyboard settings and tell it to always replace the F-word WITH the F-word. On iPhones, it’s called “Text Replacement.” On Androids, it’s “Personal Dictionary.”
