How To Erase Your Lost Phone Data

If you have lost your mobile phone and want to erase its data so follow these steps:

1. Sign in to your Google Account on android.com/devicemanager. If you're helping a friend with their lost device, we recommend opening an incognito tab in Chromeand having them sign in to the Google Account they use on their mobile device.
2. Click the arrow next to the device name to select the lost device. Android Device Manager will show the location of that device.
3. Select from the following options. You may need to enable Lock & Erase first.Ring:Rings your device at full volume for 5 minutes — even if it's set to silent or vibrate.Lock: Locks your device with a password if you don't already have one set.Erase: Permanently deletes all of your data. Android Device Manager may not be able to wipe the content of an SD card in the device. After you erase the device, Android Device Manager will no longer work on it.
4. If you're helping a friend, they can sign out when they're finished by touching Sign out at the top of the screen. If they don't sign out, they'll be automatically signed out after 5 minutes of inactivity on the website.
