Although the Auto-Correction feature on iOS devices has long been criticized for causing you to write "brain" when you meant "Brian", it is a very useful iOS feature. Because it makes it easier for you to input your sentences and increases the chances that you will get the words correct.

It is, therefore, possible to get caught up in the function of the Auto-Correction feature that you can find yourself stuck when it fails to work. This problem can present in so many ways. Here's how one of our users described it.

"When I write the text messages, a red line often appears below any misspelled words. But I don't see it. I am also not seeing any correction options. Do you know how to fix it?"

Here we will take a look at exactly why your iPhone Auto-Correction is not working and some of the solutions to fix the problem.

Why iPhone Auto-Correction is Not Working?

Like most other iOS feature issues, this problem is mostly caused by a glitch in the iOS system. It is also worth pointing out, however, that the problem can also come about if the Auto-Correction settings and other settings governing the device's keyboard are not set correctly.

Based on the most common causes of this problem, here are just some of the most effective solutions.

Solution 1. Check Auto-Correction Settings

The first thing you want to do is to make sure that Auto-Correction is set up correctly in the settings. Follow these simple steps to do it.

Step 1: Open the Settings on your device.

Step 2: Tap on General > Keyboard and scroll down to make sure "Auto-Correction" is enabled.


Solution 2. Check Spelling and Predictive Settings

You should also check whether the "Predictive" and "Spelling" setting your device are enabled. While spelling ensures that the auto-correction will work and predictive settings enable the iPhone to learn your vocabulary and suggest words as you type.

Go to Settings > General > Keyboard and scroll down to find the Predictive Settings.


Solution 3. Reset the Keyboard Dictionary

If all the settings are correct but Auto-Correction is still not working, you may need to reset the keyboard dictionary. This action will also erase all the misspelled words, allowing you to begin afresh.

Step 1: Open the settings on your device.

Step 2: Tap "General > Reset".

Step 3: Select "Reset Keyboard Dictionary".


Solution 4. Force Restart Your iPhone

If a reset of the keyboard dictionary doesn't work, you can force restart the iPhone. This will remove some conflicting settings, glitches and corrupt data that could be causing the auto-correction issue.

iPhone 6 and earlier: Press and hold the power button as we all as the home button together until the Apple logo appears on the screen.


iPhone 7 and 7 Plus: Press and hold the power button and the volume down button until the Apple logo appears.


iPhone 8 and later: Press and then quickly release the volume up button and do the same with the volume down button. Now press the power (side) button until the Apple logo appears and the device restarts.


Solution 5. Fix Auto-Correction Not Working on iPhone without Data Loss

Solution 6. Train Auto-Correction

Auto-Correction usually works by detecting a wrong word before you fully type it in and offering you the right word. But it follows your own patterns and may therefore recognize wrong words as correct ones if you type them in too often.

To re-train Auto-Correction to remember the correct word, begin typing the word and when Auto-Correction guesses the wrong one, tap the "X" in the Auto-Correction bubble to remove the suggestion. Doing this for all the words will take some time, but iOS will learn the correct words in no time, fixing the issue.
