You can trace your lost phone using the ‘Find My Device’ app and Google Maps. However, you must have installed the app before it is lost. While the phone is lost, you need to log in to your Google account that is linked to your lost phone using a computer or some other device. Pull up the Google Maps and click on the menu and further tap on the ‘Your Timeline’ option. Now, put in the date to check the location history of your lost device of that particular day.
