Android Device Manager is already a great way to ensure you can locate, lock, or wipe your phone if you lose it. You can remotely access it from your tablet or any full computer, but what if you're out and about and don't have any spare technology handy, and no way to connect it? Google has delivered a solution in the form of the latest Android Device Manager update. Now any Android device with ADM can allow guests to log in, with full access to remote location, ringing, locking, and wiping.
What’s New
So far Google hasn't posted the changelog, and the guest mode is the only thing we can find that has significantly changed. To access it, just tap the owner's name at the top and select "Guest," then log in with another Google account. All the guest's Android devices will be accessible, and there's a handy "Sign Out" button right at the top when you're done. Nice.
Download
The APK is signed by Google and upgrades your existing app. The cryptographic signature guarantees that the file is safe to install and was not tampered with in any way. Rather than wait for Google to push this download to your devices, which can take days, download and install it just like any other APK.
