"Find my phone"? Is that the thing you're supposed to do so it can be tracked if it's lost or stolen?
Yes. It's pretty effective. I set it up when I was at work, and it could show me where in the building my phone was. My ex-husband has used it a couple of times -- once it was at someone's house and he and his dad went there and got it back. The other time it was lying in the sidewalk about a mile from his home, and he got there just as some family was picking it up.
You can even set it so it beeps even when it's turned off or the battery is dead, so if it slips into a chair cushion you can dig it out.
