About a month and a half ago, Google launched its Android Device Manager website to help Android locate and erase lost devices. At launch, the web-based utility allowed users to pinpoint a device’s location on a map, sound an alarm, and erase its storage. Now, Google has given the web utility a new and very useful trick.
Just as before, Android Device Manager works on devices running Froyo or later, and it installs itself as a Device Administrator (visible in Settings –> Security). Building on previous functionality, however, Android Device Manager now lets you remotely lock your device. This is particularly useful in the event that you misplace your device but find yourself unwilling to wipe its internal storage. After all, if your normally unlocked tablet is in the possession of a friend of yours, you’re probably better off securing it remotely than you are wiping all of your precious data.
While many may wonder why this seemingly simple feature wasn’t present in the first place, we’re just glad to see it there now. You can get started by visiting the Android Device Manager website. You can also learn more over at the official Google blog._________
