I'm preparing to ship my old iPhone 6 to a new home. When I press and hold the lock button, a white screen saying "Hello" in various languages appears. Does that mean I erased all of my data? I haven't used the phone in months so I can't remember what I did to get the phone to that screen, but I want to be sure that my data is erased before getting rid of the device.
TL;DR Is it possible to get an iPhone to the white "Hello" set up screen without completely erasing the previous user's data?
