In my iPhone XR the bold, underline , italics function is not working. Sometimes it works, sometimes does not work. Any solution?

Hello avinash156,

Being able to bold, underline, and italicize text is a great feature of the iPhone. To confirm, are you having issues with this feature in all applications or a certain app? If the issue is only happening in one specific application, you'll want to complete the steps listed below. These steps can also be found in the following article. While the article references a different issue, these are application specific steps that can resolve many issues.

1. "Force the app to close."
2. "Restart your iPhone."
3. "To see if updates are available for the app, open the App Store, tap your profile icon, then scroll down to see if updates are available. If updates aren't available for the app, update the software on your iPhone or iPad.
4. Delete the app. When you do this, you might lose data that was stored in the app. Then redownload the app. Then check to see if the problem with the app is fixed."
5. 
   

If an app on your iPhone or iPad stops responding, closes unexpectedly, or won’t open

If the issue occurs in multiple apps, restarting and updating iOS are still relevant steps that can help with resolving this issue.

Let us know how that goes!
