iPhone stopped capitalizing proper names and "I"

If your iPhone has stopped capitalizing proper names and "I," these are the options that you can try

1. Check your keyboard settings: Go to Settings > General > Keyboard and make sure that "Auto-Capitalization" is turned on.
2. Check your language settings: Go to Settings > General > Language & Region and make sure that your language is set correctly.
3. Reset your keyboard dictionary: Go to Settings > General > Reset > Reset Keyboard Dictionary. This will reset any custom words you have added to your dictionary, but it may fix the capitalization issue.
4. Restart your iPhone: A simple restart can often fix issues like this. Press and hold the side button until the "slide to power off" option appears, then swipe to turn off your iPhone. Wait a few seconds, then press and hold the side button again until the Apple logo appears.
5. Check for iOS updates: Make sure that your iPhone is running the latest version of iOS. Go to Settings > General > Software Update and check for any available updates.

If the issue persists even after trying these steps, you may need to contact Apple Support or take your device to an authorized service center for further assistance.
