How to Fix the Latest IPhone Bug in 5 Steps
I upgraded my IPhone to 11.0.3, and then it started changing "I" to a weird ? in a box. According to Apple Support, changing the the keyboard setting will fix this bug.
Step 1. Go to Settings
Step 2. Select Keyboard
Step 3. Select Text Replacement
Step 4. Click on the +
Step 5. Type an uppercase I in Phrase. Type a lowercase i in shortcut & Save!
So far, this solution has worked for me. But, I'm going to bookmark Apple Support just in case!
