My phone was stolen a week ago. I went home to log into my Google account in order to erase my device through Android "Find My Device". There was a check sign next to the erase, but it is still showing up on my account. I watched videos that told the owner that the phone was factory reset and I think my phone has not. Does this mean the thief has access to everything?
When you press on the erase option on the find my device, page, it tells you "If your device is offline, erasing will being when it next comes online" This is because Google cannot erase your device if it cannot connect to it.
The check mark you see, tells you that you put it into "erase mode" but it will only take place when it's online.
Had the device been online when you tried to erase it, it would have told you that it's online, and you would have seen the actual location.
I must conclude that the thief turned the phone off as soon as he got it. He could then put it through factory reset, or access your data while in airplane mode.
If you had a lock on your phone, the chances of him getting passed it, are very small. But If you did not have any lock on it, then he could have access to your data, and there's not much you can do about that.
