Apple phones have a Find my iPhone feature, did you know that Android phones have something similar?
You can ring your lost phone on a webpage using a desktop computer, or on an app using a tablet or other device.
The webpage is called Android Device Manager, and can be found here: https://www.google.com/android/devicemanager
You can also lock or erase your device if it’s lost.
The app is called Android Device Manager and can be found in the Google Play store, or here: https://play.google.com/store/apps/details?id=com.google.android.apps.adm
Finally, another option if you can’t find your phone around the house, but don’t have access to another phone to call it is: www.wheresmycellphone.com
