This is very easy and simple way to find out where your phone is. If you have lost your Android phone then open Google home page with any browser. Then log into the account which you've used in the phone you've lost. As you know to use Google's services you have to use a Google account, so in this case you must have used an email address for the that lost phone.
Ok, after logging in, it will say connecting your phone and screen will show up where it will say "allow" hit the allow and then you will get all the details. And then you will have three options. Ring, lock and Erase. If you hit erase, your phone will be reset. That means you will lose all your data, and your memory card might get formatted too. I hope this tip helps you.
