Hi everyone ,
Thanks for a all contributors and for answering questions.
From my understanding, in an encrypted device, the phone is really secure after turning it off and before the first decryption/unlocking (BFU), after the device is first unlocked/decrypted (AFU) it is not as secure even if it is locked again because the encryption keys are stored in RAM. For extra security, would it be possible and hard to implement an option in the encryption settings to make the phone like in BFU every time the phone is locked ? Even if it takes longer to unlock each time of course
