Hi,
just bought the Huawei P8. Im wonder if my phone is now fully encrypted, including the SD Card.
1. Internal Storage
After factory reset there was no screen lock (just swipe to unlock). I clicked 'encrypt phone' and it took only a few minutes. AFTER that i could still swipe to unlock, there was no option to set a password during the encryption process. So I set the password afterwards. Now the pw must be entered to unlock the phone.
Does this mean the internal storage is now fully encrypted and can not be accessed without the password? Even though i did not set a password before the encryption?
What if someone where to remove the internal memory module from the phone?
Does the encryption encrypt ALL files in the internal storage or just certain areas?
2. SD Card
That one was strange, too. I clicked 'encrypt SD Card'. There i had to set a pw in advance.
But the encryption also took only a few minutes. That seems odd because the 64 GB SD Card was half full. This should have taken hours to encrypt.
Can I be sure alls files on the SD Card are fully encrypted now?
3. Why I am asking
Before I had the Samsung Galaxy A5.
When encrypting the device you had to set the pw in advance and it took much longer. That seems logical to me.
When encrypting the SD Card the phone asked me if I wanted to encrypt all files on the SD Card, including Fotos, Videos, MP3s etc. It warned me, that this might take a long time. Encrypting the SD Card with some 30GB on it took severeal hours. That also seems logical to me becaus SD Cards are much slower than the internal storage. So I am wondering why the Huawei P8 only took a couple of minutes for the SD Card.
Can someone please elaborate?
I am especially interested in having my photos (which save to the SD Card) encrypted so nobody can access them when my phone is stolen. I also have company emails and such on the phone.
Hi,
on internal storage... Data Partition would be encrypted. I am not sure if cache partition would also encrypted. File's from internal storage would be saved in Data, so all files are encrypted.
But SD-Card wouldn't be encrypted...it's only password protected. That's why it takes only few seconds to set the protection.
If you set a password for internal storage, you could choose to set the protection in the Boot process. So before the whole system boots up you would be questioned for the password.
Thanks for the answer.
I activated the boot password.
What use does the sd card password have? I tried to put the sd card in my computer and the card wasn't even detected. Does this mean nobody can access the files without the password? What is the difference to a full encryption?

Hi All,
I have an S5 - G900F running Android 5.0 stock and I would like to encrypt the SD card. As I am often forced to factory reset, sometimes because the phone boot loops I am not always in the position to decrypt the SD card first.
I would like to know: can I access and backup the encryption key for the SD card so I can access the data after a reset. Or failing that, some encryption software that can secure the whole card and works with fingerprint log in.
Thanks
John
So I bought the S7 edge popped in my SD card and encrypted It. The card was giving me some issues so I backed up my files on my Pc formated the SD card and reloaded the files (MP3s) now when I go to play many of the songs they don't play and just say "sorry unable to play file type" it's odd because about half of the songs do work any ideas for fixing this I have a quite a large music collection and it would be quite pain staking to have to download these one by one again
Would encrypting them and decrypting them help?
Really none of the brilliant minds here at Xda have any idea?
Did you copy the files off with the SD in a pc reader or via mtp from the phone? I would guess the the base encryption key data is different since you reformatted the card, it would make sense to me because otherwise there would be no point to supporting SD encryption.

SD in a pc reader. Is there anyway for it to read the files again?

If Google did their work well, not likely.
I don't know the details but the only consumer hope would be with the card inserted in the device that formatted it as theoretically the encryption of the SD card should be done with private key data that is tied to the device it was formatted within (in addition to whatever private data you provided such as a PIN). Otherwise it would be too easy to just move the card to another device to decrypt the data.
I've seen some references to the Android SD card encryption *not* necessarily encrypting media files (music, movies, pictures?) so it's possible those files were not at all encrypted - which is substantiated by the fact that you can play SOME of them.
It may be that the files that don't play are, unfortunately, simply, corrupted data and not encrypted at all. ;^(

I had the exact problem, it seems to be some issue with a lot of S7's from from my research online. After almost giving up after a few weeks I finally did find a fix which hopefully will work for you and anyone else who has encountered/ will encounter this problem. Here are the steps I took:
1. After the sd card became unresponsive on my phone after encryption, I transferred all my files from the sd card to my PC. I had to do this via the sd card slot on my laptop as the card was not being recognized when connected via the phone.
2. I then formatted the sd card on my PC. For those not familiar with the process just right click on the card in "my computer" and select format then quick format.
3. I then reinserted the card into the phone to make sure it was recognized, then removed it again, inserted it into the PC and transferred all the files back over.
4. I went into my phone under security settings and changed lock screen security to "none" while leaving fingerprint on.
5. I put the sd card back into the phone with the files. They won't be accessible as yet since they're encrypted but the next step is to go ahead and encrypt the sd card. Wait however long you have to, for me it took less than a min. After this go back and decrypt the sd card, let that process run through then the files should now be decrypted and accessible. If the sd card goes unresponsive again just try again by formatting the sd card and putting the files back, this time maybe a few files at a time.
If this method works for you I would suggest backing up your data frequently and staying away from encrypting the sd card at least until samsung/android release a fix for this issue.
Hey there fellas i am new to these forums so i dont exactly know how this thing works so bear with me and my english.
I had samsung J5 which i encrypted both (sd card and device) but somehow ive broke my phone and but thankfully was able to recover my sd card. but when i insert my sd card into my new phone the data won't load up although its shows the names and amount of files it contains but no picture,videos or audios. i remember my password which i used for encrypting the (card and device) but it doesn't prompt me to put my password and processes to decryption. please help me out how can i safely decrypt the SD card with all my data.
Hello,
I see in security options one for put a password to SD Card, but it does not encrypt the SD. Also I have seen in internet it is very easy for a thief to get the password in a PC. Do you know if is there any way to encrypt the sd card? also is internal memory encrypted?
thanks.
Hello, i own Xiaomi Mi A1 with rooted Android 8.1.0 and i got 32GB Samsung SD Card.
I was using it as internal storage, i wanted to get rid of it to make space for another SIM.
I made sure that there are no apps - Moved everything to internal space.
I checked usage of SD card and there were only system and apps, a said fine, i am ok with deleting and reisntall some apps.
So i formatted the SD card ("Use as external storage")
And then i noticed all my pictures are gone. If i am right, when you use SD card as internal storage, device encrypts the card, then it was formatted.
I immediately took card out of phone. I am still own this device, so is there any way to recover encryption key or something?
Now i am tryin recover files with app PhotoRec, but it doesn't seems to get any files.
Any idea how to get photos back? I don't have updated backup of Google Photos.
Sorry but you have no hope, did they not backup to google photos or did you not have that turned on.
So there is no way to recover content of card and then decrypte?
I did not turn that on intentionally, i thought i am smart enough not to do such a stupid stepwithout backup, lol.
EDL Mode
I had the same problem. I only managed to solve via EDL Mode. On youtube there are several videos teaching how to do it.
