    No. They need your password. Without that, there is no way to decrypt anything you have encrypted.

    Advanced encryption works using a set of keys (not to be confused with your password). Your password is "hashed" into a set of encryption keys, which is used by the algorithm to encrypt the device. The hash is a one time thing - two people using the same password - say "password123" - will end up with a different "hash" used to encrypt their files. The end result is: If you wipe out those keys, you lose any chance of getting your data back, even if you use the same password. The keys will be different.

The same with my lock screen password. Just a PIN setup.
    Using an S4...but looks like the same issues.

    This doesn't seem to be of great use.

    First, the lockscreen and encryption pws must evidently be the same. That's annoying since screenlock needs unlocking constantly and the encryption only when the phone is booting after a power down. The encryption pw should be differentiated. Can it be, or am I right?

    Second, the encryption only works if the phone is powered off. That's almost never. So, someone swipes my phone. All they have to get through is the screenlock. How does encryption much help? Why bother?

    What am I missing? It sounded like a great security feature. It seems very insecure.

    I have a Note 2 Verizon Android 4.3 with a 16 GB internal SD card (90% full) and a 64 GB external SD card (30% full). After encrypting the phone to comply with an employer's policy, I find that after every restart or power-up, the system "encrypts" the external SD card again, taking 16 minutes to do so. During this time the Vold process is using 25% of CPU time, so I figure it's continuously using one of the quad cores nonstop to run that. The external SD card has an unmounted status until it completes, so all files on it can't be accessed until it's done. Has anyone else experienced this? I have gone through the recommended procedure of reformatting the card as exFAT using my laptop.

    Yes, my phone does exactly the same thing. I never timed it, so I can't vouch for 16 minutes long, but it does take a number of minutes for the phone to do its thing. This only happens whenever I manually do a restart. The whole restart process takes a number of minutes, plus the phone takes additional more minutes for encrypting the external memory card. I've learned to just tolerate it until it's all done. I've thought about unencrypting my device (and memory card) just so I don't have to type in a long password (versus a 4 character pin), but I've gotten used to the hassle for some time now. By the way, the reason I periodically do a manual restart is whenever I feel my Note 2 is getting sluggish in response time. After doing a restart, things seem to improve. I manually restart my phone at least once a week or more.

    Glad to hear I'm not the only one with the problem. Wish there was a answer for it. If I let my battery run down to zero, I have to go through that 16 minutes again. Also, I have an app from JVC that tries to organize my music by its mood, and that app now rescans the music on my Ext SD card after every restart, as if I'd replaced the SD card.

    You generally don't want to restart your phone if you're already at low battery life, cuz as you already found out, restarting requires a bit of juice. I'm always at 100% battery life, or have the phone plugged in prior to doing a restart.

    Dear Friends,
    I am using Samsung Galaxy Grand 2 since 6 months. Today morning i want to see what is encrypt Device though i have only vague idea about it, so i entered the password and began the process. When it was 6% completed i was not 100% sure what exactly it is about so removed my battery so that the process would be stopped. When i turned my mobile on, all my data was disappeared and lost everything. Please help as the photos and contacts in my mobile are very important to me.

    Hey Everyone, I'm trying to decide on a password. I have a really good memory and can remember super long ones. looking at the encryption process on my note seems to imply that I can only use the password unlock screen option only when the phone is encrypted as it does not permit me to begjn the encryption process when I have any other unlock settings. I don't actually mind putting a super long password when I first turn on the phone but if I have to put it into the unlock screen every time I lock my phone that will be too anoying. In my old galaxy S, my password and unlock screens were completely independent. Is it the case here? Have anyone been able to encrypt the phone and, once the phone is encrypted, switch the unlock screen to say pattern or pin or an easier password once the phone is encrypted or are we forced to unlock the screen with password we are encrypting our phones with?
