Phones are a really important part of the day to day lives that most people end up living on a regular basis, and this means that if your phone ever gets lost then you are probably going to be extremely upset about what has just happened. A big part of the reason why that is the case has to do with the fact that your daily tasks usually require you to have a phone, not to mention the fact that you would no longer be able to contact anyone which is another thing that would prove to be a source of serious frustration for you all in all.
Now, you must go to the police if your phone gets stolen so that you can report the theft and make it so that someone who is in a position of power would know that such a thing has happened so that they can do something or the other about it. At that point in time you could potentially leave it to the authorities, but you might want to take matters into your own hands which is why using the find my iPhone feature is going to be great for you if you think about it.
This feature will give you a location that you can go to, and if the person that stole the phone was not very smart then it might just lead you directly to them. At that point you will have successfully found your phone and you can tell the police that you now know where it is, giving them the chance to move forward and get your phone back for you as well as punish the person that was responsible.
