Remotely lock your Android device with Android Device Manager5
Google has added another very important feature that enhances the safety of your Android model. Now, the Android Device Manager will remotely lock your Android phone. This actually helps you delay that gut wrenching moment when you wipe all data off your phone. With the remote lock, you can buy some time to find the device before you go with the nuclear option.
With the new feature, it doesn't matter if your Android handset is locked down using a pattern, PIN or other method. The Device Manager will override it and allow you to create a new password that will be used to open the handset once it is back in your possession, if it ever is. The feature will also allow you to turn off the screen if it's on. Just make sure that under the security section for settings, the Android Device Manager is listed as a Device administrator.
