Showing "error" on my screen

Jom1234,

Thanks for the additional information regarding your Lock screen error message.

Do you notice if this happens when you're attempting to perform a specific action from the Lock screen? Or, if you have a specific application opened and then go to lock your screen, is that when this appears? What happens when you tap Accept or Cancel from this screen? Does it then go away? Are all of your applications up to date in the App Store?

We'd like to have you try force restarting your device next: Press and quickly release the Volume Up button. Press and quickly release the Volume Down button. Then press and hold the Side button until you see the Apple logo. Does that stop the Error screen from appearing again?

If the Error screen continues even after a force restart, lets have you reinstall iOS on your device, in the case this is a software hiccup. Follow the steps in the section titled, 'If your device turns on but gets stuck during start up' in this article: If your iPhone, iPad, or iPod touch won't turn on or is frozen. The title may differ from your issue, but the steps there are the best ones to guide you through reinstalling iOS. Please be sure to choose 'Update' as mentioned in step 4, and not 'Restore'. 'Update' will reinstall iOS without data loss. 'Restore' will erase your device which we don't need to do at this point. It's still a good idea to backup your data before performing that step: How to back up your iPhone, iPad, and iPod touch

Keep us posted.
