Deleting CRITICAL Imminent Threat Alert

I'm guessing you have increased the text size on your phone or are using zoom to make the text larger and the text is now so large that the entire message doesn't fit on the screen, meaning you can't reach the button to dismiss it.

Force restart your phone.

press and release volume up, then volume down, then press and hold the side button until you see the apple logo.

Where did you see this?

If it was while browsing the internet, then it is just an ad to scare you into subscribing to some service or downloading some software that you do not need. Navigating off of the page will remove the ad. A screenshot may be helpful to visualize what you are seeing.

Are you able to use your finger to slide the alert either up or sideways? If it is frozen on your iPhone screen, Force Restart your iPhone --> Force restart iPhone - Apple Support

some people view random internet popup windows as system warnings if this is the case for you

then you can disable those scam popups by reading

Got it. I was able to move it around and when I shifted it left i got a box that said 'clear'. That got rid of it.

Thanks.

You're welcome.
