You may use Alexa devices to find your phone.

For example, you forget where you place the phone and would like it to ring.

To do this, first you would need to link the find my phone skill with your alexa device on the Alexa app.

After successfully linked, use command

"Alexa, find my phone"

Alexa then will send out security code to your phone sms for verification.

Tell alexa the code and the find my phone setup is now completed.

Whenever you would like Alexa to find your phone, just repeat "Alexa, find my phone", and your phone would start ringing now.
