How to find a lost phone

It depends on what the smartphone is for you -

1. An expensive device - you must try to return it,
2. A device with valuable data, for example. photos, account accesses, bank details ... - all need to be deleted.

To return phone

In many cases, you can understand where it might be if you lost it or left it.

If the place is completely new to you, then it is in the hands of another person.
Armed with this information and call, try to negotiate with this person, in terms of what you know where he is.
Just remember the story of how one person found the iPhone and wanted to return it. At once there was a call with a demand to return and threats. The man listened to it and dropped the iPhone on concrete all over the place.
A natural response to threats, that's before this is not necessary.

There is still the possibility, when you have found an approximate location of the phone and you need to clarify, you can turn on the forced call, it will ring loud even if the phone is off, minutes 5.
