Click on the Ring icon and a message will appear telling you that your phone will now ring at the highest volume level.

The phone will continue to ring for 5 minutes unless you find the phone in which case it will stop when you press the power button to make it stop.

How to Lock the Screen of the Missing Phone

If you still haven't found your phone after using the Ring function then you need to make sure that it is secure.

In the first instance, you should create a lock screen which will prevent anyone with unauthorized access to getting in.

To do this, click on the Lock icon.

A new window will appear and you will be asked to enter the following fields:

  • Password. 
  • A message.
  • An alternative contact telephone number.

By providing this information not only will you be able to secure your phone, but you are also helping the person who finds your phone as they will know who to call to arrange for its safe return.

You should always set a lock screen on your mobile phone and you should not wait until it is lost to set one.

Your phone is usually logged in to multiple accounts including social media and email and without a secure lock screen, anybody who finds your phone has access to all of your mobile data.

How to Erase All of the Data on Your Lost Phone

Erase The Data On A Lost Android Phone

If after a day or two you still haven't found your phone then you will need to think about erasing the data and setting it back to the factory settings that were on the phone when you first received it.

If the phone has been stolen, then in the worst case scenario the phone could end up in the hands of somebody who can get more value out of your data such as your contacts, your email, and other accounts which may be accessed via apps installed on the phone.

Fortunately, Google has provided the ability to erase your phone remotely. If you aren't going to get your phone back at least you can protect your data.

To erase the contents of the phone click on the Erase icon. 

A message will appear telling you that the phone will be reset to factory settings.

Obviously, you only want to do this as a last resort but rest assured after pressing the button your phone will be reset to the state it was in when you first received it.

You should still consider changing the passwords to all of the accounts that are stored on your phone, just to be safe.
