I just started seeing this screen appear on my phone. It's an iPhone 6 with iOS 9.1 - factory unlocked - never jailbroken - never done anything even remotely unusual with it. It's obviously a hack of sorts. I didn't press "accept" or "decline" just took a screenshot. There is no "app" visible on the home screen, and nothing running in the background (that I can see).
Can't find anything online that relates as to what this could be, or where it could come from. Very curious to know.
- The back button just takes you to the home screen.
- I wiped the phone to factory settings, and the screen reappeared while I was still on the "hello/welcome" page.
- This is not a support question. I 'm curious to know if anybody has heard of this exploit.
