As I know, when the phone is locked that means it has been encrypted.
So how do Google and Samsung's "Find My Device" service bypass Android's Secured Lock Screen? Does it mean they have our decryption key?

1When the phone is locked it doesn't necessarily mean it's encrypted. Usually it's the other way around.– Izzy ♦Commented Apr 14, 2018 at 14:38

@Izzy, isn't it File-Based Encrypted with direct boot (source.android.com/security/encryption/file-based) ?– IT-FanCommented Apr 14, 2018 at 16:45

1As I wrote: Encryption will certainly require a "lock" (password) – but a lock doesn't require encryption. Screen lock usually doesn't: while you lock your screen, the file system stays "decrypted".– Izzy ♦Commented Apr 14, 2018 at 16:50

@Izzy, even the file system stays "decrypted" but the rest still stay encrypted right ? We still need the key to decrypt in order to fully use, don't we ?– IT-FanCommented Apr 15, 2018 at 1:30

1I don't understand what you mean. When locking the screen one simply locks the screen, nothing else. If encrypted, the file system always "stays encrypted" – even if the device is unlocked and you're working with it. Knowing the encryption key and passphrase, the OS can access it. As soon as you shut down, the passphrase is forgotten and the file system thus inaccessible. But that has nothing to do with locking/unlocking the screen. IOW, "bypassing the lock screen" doesn't touch encryption, AFAIK.– Izzy ♦Commented Apr 15, 2018 at 8:37
