Caps Lock Issue on new Iphone 17 - iOS 26.2

This is what happens when you enable Caps Lock Switch to ON

On iPhone, the Settings → General → Keyboard → Enable Caps Lock option controls whether you can double‑tap the Shift key on the keyboard to lock it in uppercase mode.

Here’s how it works:

• When enabled:
  • Double‑tap the Shift key (the upward arrow), and it will stay highlighted.
  • All letters you type will remain in uppercase until you tap the Shift key again to turn it off.
  • This is useful if you need to type acronyms, headings, or long strings in ALL CAPS without holding the Shift key for each letter.
• When disabled:
  • Double‑tapping the Shift key won’t lock it.
  • You’ll only get uppercase letters while holding the Shift key for each character.

In short, it’s a convenience toggle: Enable Caps Lock lets you type in ALL CAPS easily by double‑tapping Shift.

"Caps Lock Issue on new Iphone 17 - iOS 26.2: I have seen several threads reporting this same issue, along with the recommended fix of making sure the Enable Caps Lock Switch is ON by navigating to Settings --> General --> Keyboard --> Enable Caps Lock. Unfortunately this is not working even after powering the phone on and off. I can force capital letters by holding down the Shift key but that is inconvenient and is a problem for letters near the Shift key.[...]"

Turning ON Caps Lock:

Double-tapping the up arrow (shift key) on your keyboard, it will lock.

"I need to tap the Shift key each time for each individual capital letter - double tap does not work."

-------

Getting Double-Tap to Work for Caps:

If this double-tap doesn't work, ensure that "Enable Caps Lock" is turned on in Keyboard Settings.

1. Go to: in Settings
2. Tap: General
3. Toggle On: Keyboard

"Caps Lock Issue on new Iphone 17 - iOS 26.2: Unfortunately, as stated in the original post, that does not work either on my Iphone. Enable Caps Lock is ON in Settings --> General --> Keyboard, but double tap does not cause Caps Lock to be ON.: This is actually a minor inconvenience, but it does appear to be a bug at least on my phone."

Thank you or clarifying this.

Getting Double-Tap to Operate:

Aside from reporting it, you might be able to fix this by resetting your iPhone to Factory Settings. Just be certain to take some screenshots of your Home Screen(s) and Settings app, so that you can remember what was laid out and how things were configured, respectively. Export items prior to the Factory Reset. It will take some effort, if you have lots to back up, and want all items to be the same. Elsewise, it's a matter of awaiting a new update release.

IMPORTANT: Be certain to back up your iPhone to a computer prior performing the Factory Reset. That way, you can have something to restore it from, should anything go wrong in the process of doing so.

"Thank you for the detailed response - I do appreciate the quick responses.: I am reluctant to perform a Factory Reset at present. My actual plan is to take the phone (IPhone 17 - not Pro) back to the Apple Store after Christmas (on Friday), where I purchased the phone, and report it to the staff there. The phone is brand new, less than a week old - this issue appears to have existed since I started Messaging. I will perform the backup to PC (Windows 11) as you suggested before going to the store."

You are most welcome. I was not aware that this is a new iPhone.
