I lost one of my phone 2 months ago. I've sometimes checked Android device manager to locate it and try locking it, but recently my lost phone disappears from the list ! How it can happen ? Does a person know the way to skip this link in order to use or to sell the lost phone ? I still have the original box of this phone (with its IMEI). Please help, thank you.
As soon as the new "owner" factory-resets the device, it no longer has a Google account associated – and thus the link to ADM dies. Same if the account is removed from the device: Google services no longer have a way to query the device using your account information, as the device won't recognize those anymore.
There are also other possibilities:
- battery is empty, so the device died.
- battery was removed
- dedive went into airplane mode
- device was placed on a train track, and a train passed on top of it
- device was drowned in the sea and short-circuited
Many more possibilities, but I better stop here – you've got the idea ;)
