You don’t need to be a genius: Just be aware

Be aware of smartphone theft
You should know your phone
Every smartphone is unique. It comes with a unique description also and it is important for you to know its numerals. The three important numbers you should copy and keep safe are the serial number of the device, the model number, and the unique identification number of the device. In the event the smartphone is stolen, you’ll have to report these numbers to your carrier and the police. You can find the IMEI (International Mobile Equipment Identifier) for most phones by simply dialing *#06#. The number displays automatically on your screen.
Always lock up your Smartphone

Activate your GPS / Location Tracking Apps
It is important to install an application that allows you to monitor the whereabouts of your phone. Although thieves have ways of turning the phone off or thwarted the tracking, it is a good practice to also install such an application. Many cell phones have been recovered that way. You can also use the Apple’s Find My iPhone app that can be downloaded for free from iTunes or Apple’s iCloud. For Android phones, you can also use the Where’s My Droid tracking device.
Contact the police as soon as possible
You should contact the police immediately after your phone is stolen and give them the IMEI, the serial number, and the password of your phone so they can log to your tracking device remotely. The next place to call will be your carrier. Let them know that your phone has been stolen. You should change your passwords to sites you have accessed using your phone such as Facebook, Twitter, Email password, banks and other sites. You can brick your phone as well, making it absolutely impossible for anyone to use it. Police says thieves have ways of modifying the IMEI, and some stolen phones often end up in foreign countries where the carrier cannot have any access.
In situations where your life could be in danger, it will be wise to let go of your phone. Make sure you get a detail description of the thief and then contact the police to make a report.
