Locate Yours Lost Android Phone

Similar to Find my iPhone above for iOS, Lookout Mobile Security provides a web-based control panel from which users can locate their Android device. Once the app has been installed and your device goes missing you’ll be able to disable silent mode to sound a loud alarm, remotely enable GPS to facilitate locating your device and view the location on a map.

The software also provides a good antivirus solution, making it an all-rounder in terms of protecting your device and data. However, there’s always the possibility of your phone going missing without any tracing software installed, and in these instances it’s reassuring to have Plan B available to you.
Also developed by Lookout, Plan B can actually be installed after your phone has been lost via Google Play. It will automatically start when installed and email the location of your phone to your Gmail address. You can then query for location fixes by texting “locate” to your number from a friend’s phone. While limited in its uses, Plan B is a great last resort for missing phones.
