Hi! My iphone 7 was stolen in a park. I found out it in 1-2 min. I took my friend's phone and tried to call my phone. First were tones, but then the phone was turned off by the thief. So I could not use the Find iPhone app as well. The suggestion: you can turn off iPhone only after entering the password.
