Android has introduced a nifty feature that is web based. The Android Device Manager you can visit it here: https://www.google.com/android/devicemanager however it works best on a computer that web page.
There is a function to ring your device at maximum volume, or change your device name.
You can also see the location of your device on a map and the day your device was last used.
You can also send a notification to the device.
You can even perfom a complete factory reset and erase all the data on your device.
However, after doing that you are no longer able to control your device remotely unless you re-register your device with Google.
I actually saw a device that I lost this year on the device manager and it is in Mutare as I speak…
I bet now I will catch the thief who stole my phone.
