My friend lost her phone and she received an email from Samsung which states that another Gmail account (her classmate’s Gmail) is logged into her phone. When the said classmate was confronted, she denied it and claimed that she borrowed the phone and signed in a long time ago. Is her reason valid? Is there a way to know when a Gmail account was logged in to a Samsung phone?
Go to the Google account, in the device whereabouts. It shows the location of all the devices logged in, and the last known location for offline devices.
