Suppose I lost my phone and I could use find my phone to find it. The problem is I don’t have my phone in order to find my phone with. I don’t have a computer I don’t have a laptop All I have is a phone. How on earth would I use find my phone to find my phone?
I used my PC to wake up my android phone; there a Google thing that will make it don’t for five minutes even if it’s on silent. The two times that wasn’t easily accessible, I asked someone nearby to call my phone. Once I found it immediately; the other time, I found it later from the “missed call” beep.
