Fixing Spelling Mistakes on Android: Beyond Autocorrect

August 16, 2026•4 min read•SmartType Team

Autocorrect misses more than it catches. Here is how to fix spelling — and the mistakes autocorrect creates — across whole sentences on Android.

Autocorrect is helpful until it is not. It fixes obvious typos but changes correctly spelled words, misses context, and cannot tell "their" from "there." If you have ever sent a message that autocorrect quietly ruined, you already know its limits.

Why autocorrect is not enough

Autocorrect works one word at a time and guesses from a dictionary. It does not read the sentence, so it cannot catch a wrong word that is spelled correctly, a missing word, or punctuation that changes the meaning. For anything that matters, you need correction that understands the whole sentence.

Fix spelling across the whole sentence

An AI keyboard reads the full sentence and corrects spelling, grammar, and punctuation together, then replaces your text in place. That catches the mistakes autocorrect makes as well as the ones it misses. See the step-by-step in our guide to fixing grammar while typing on Android.

Teach your keyboard your words

Names, brands, and slang are where autocorrect fights you most. A custom words dictionary lets you add the words you use so the keyboard stops "correcting" them. Combined with full customization, you get accurate typing that actually fits your vocabulary.

The bottom line: keep autocorrect for quick typos, but add an AI grammar keyboard for the sentence-level fixes autocorrect will never make. See the full AI grammar keyboard feature for details.
