Android: If you’re not using the Android Device Manager to help find your lost phone, we highly recommend it. What happens when you actually lose your phone, though? Thanks to a guest mode in the Android app, you can use your friend’s phone to find your own.
The Android Device Manager app allows you to quickly locate, lock, or wipe your other devices. However, you can also use the guest mode to allow someone else to quickly log in and find their device. This makes it much easier to help a friend find their phone, as the only alternative is to log in to their own account from a laptop, which may not be as easily accessible. In any case, if you’re not using ADM to track your phone in case of an emergency, it’s highly recommended you set it up now.
