Unauthorised pop-up 'Scanning Device' on iPhone

It's a scam, presented by some Web site or app. Web sites and apps can't actually scan your phone (although an app that has been given permission to access things like photos, contacts, or you location can certainly abuse the access it has been given).

What it is probably trying to do is to

• Get you to pay for some worthless "security" app to solve a non-existent "problem", or
• Directly contact criminals posing as "tech support" so they can rip you off directly

If you can figure out which Web site or app is presenting it, you may want to avoid visiting that Web site or using that app in the future.

Your phone is not being scanned, it is a scam message designed to get you to purchase unnecessary software or phish for personal information.

If you see this while browsing in Safari or any third-party browser, just ignore it — it’s spam.
