Auto Capitalization Not Working On iPhone

This issue has recently been reported by Evelyn on our iOS 15.5 review page:

“Ever since updating to iOS 15.5, my autocorrect and auto-capitalization stopped working. It’s turned on.”

How To Fix Auto Capitalization Not Working

These are the most common troubleshooting options:

1. Auto-Capitalization vs Caps Lock

First of all, let’s be sure that you’re not confusing Auto Caps with Caps Lock!

Auto Capitalization vs Caps Lock

As mentioned above, auto capitalization will only capitalize the first letter of the first word from a sentence. If you’re looking to have all letters capitalized, the option is called Caps Lock!

Caps Lock is enabled when you double-tap the shift key on the iPhone, iPad or Mac keyboard. To disable it tap the shift key (upwards pointing arrow) once.

2. Turn On Auto-Capitalization

Next, make sure that the feature is enabled. It should be turned On by default in iOS, iPadOS and macOS but it’s alway good to double-check:
turn On Auto Capitalization on iPhone

  • Open Settings and tap on General.
  • Scroll for Keyboard.
  • Check Auto-Capitalization, under All Keyboards.
  • Tip: Do mind punctuation. Auto-Capitalization detects the end of the sentence and capitalizes the upcoming letter only when you type a period, exclamation mark or a questions mark!

On Mac: Go for System Preferences -> Keyboard. Click on Text and make sure that ‘Capitalize words automatically’ is ticked.

3. Reboot Device

Minor glitches might cause Auto-Capitalization not to work on iPhone. When it happens try to restart your device. A fresh boot will flush any minor issues and Auto Caps should start working again.

How to: Click and release Volume Up, followed by Volume Down and press & hold the Side Button until the iPhone screen turns black and the Apple logo is displayed on the screen.

On Mac: Simply reboot the computer by clicking the Apple logo in the top-left corner of the screen and selecting Restart…

4. Reset Keyboard Dictionary

If Auto Capitalization and Auto Correct are still not working on iPhone, reset the keyboard dictionary and see if it makes any difference. This option is somewhat hidden in iOS 15:
