I recently upgraded my phone (Huawei G8) to android version 6.0.1
model: Huawei G8 RIO-L01
Build Number: RIO-L01C185B321
EMUI Version: EMUI 4.0
Android Version: 6.0.1
Custom Version: CUSTC185D005
I enabled encryption and the phone asked for password at boot time, which was normal. However, I then configured "accessibility” option ("switch access" for testing purposes) and the phone stopped prompting PIN/Password at boot time. The normal remedy of this problem over Internet is to disable accessibility and then reset PIN/Password but this did not work for me. No matter how many times I reset PIN/Password, the phone never prompted PIN/password at boot time.
So I tried encryption without enabling any accessibility option and it seemed to work as expected i.e. prompted PIN at every boot. However, as soon as I changed PIN (just for the sake of testing), it stopped prompting.
This phone also has no "Secure start-up" option to specify PIN at startup/boot explicitly. Having no password at boot sort of defeats the whole encryption purpose.
Anyone has solution to this issue? I did not try encryption in the old version (android 5) on this phone so I can't really say if this issue was present in earlier version as well.

Hi Guys,
My OnePlus 3 ist rooted, open Bootloader + TWRP.
Oxygen OS 3.2.4 is running. First time I used the device, encryption was offered to me - so I set it up.
I than used the phone for about 2 months, always had to enter a Passphrase when I rebootet.
I noticed, that if I use TWRP I can browse through my personal files without entering any credentials.
System-Preferences says: "Phone Encrypted".
Do you have any suggestions for me?
I´ve found the solution by myself.
Anyone who is having the same issue, read this thread: http://forum.xda-developers.com/oneplus-3/help/questions-encryption-unlocked-op3-t3427360/page2
You have to set up the display security again and activate the checkbox "PIN/Passphrase is needed to start the device".
I noticed that when I enable "PIN on boot" in security settings (when setting a PIN, it gives you the option to require the pin to boot - to my understanding it's hiding the decryption key for /data in another boot image, which then decrypts the key and hands over the boot process) I can briefly see a "Android is upgrading" message before I can enter the PIN.
It does not take long, it just does this on every boot. Note this is for the decryption only, it's not for the "regular" Android lockscreen that comes later.
I was wondering if there's anything wrong with this, or if it's just like this. It's not a major annoyance.
Maybe someone else on 3.2.7 can check and let me know.
Thanks!
I'm having the same thing here on 3.2.7 but never really wondered why tbh
I used to see that but I removed the "pin on boot" option as it is just annoying as it means the phone stops in the bootup process and you have to manually continue it. If you turn that off then the phone still requires a pin entry instead of fingerprint to unlock the first time after booting.
That's true. But it means your system is still much easier to break into. When Android has fully booted, the data partition has already been decrypted. Pin on boot (to my knowledge) unlocks the partition only after the pin has been set.
I have encrypted my data on the M9 (see settings->storage->encryption) . Every time you reboot the phone, a prompt for the password (in my case a pattern) appears before the phone proceeds and decrypts your data. A failed attempt after 50(?) tries resets the phone to factory. Currently, the encryption option in settings is checked and not modifiable but rebooting never produces a decryption password query?
This is a SPRINT phone Android Ver.: 7.0 Security Patch level: Feb 1. 2017
Don't quote me on this but I think it applies to turning the phone off and back on. Once the phone knows the key it's pointless to keep asking every time you unlock the device because if you know the pattern then it is obviously you..
If anyone can help that would be awesome - this is the first time i have encountered this problem on an android device.
one of the first things i do is remove encryption on my android phones because
1. i like the option
and 2. i notice a considerable amount of difference.
now starting from Pie we have metadata encryption with file encryption
removing metadata encryption causes 0 problems.
however when i remove file encryption i run into a problem
i am un-able to setup a fingerprint (the option isnt even there anymore)
also when i set up a PIN, i am unable to change it (it says incorrect pin)
when i use the pin to unlock the phone, it says "wrong pin" but it works in unlocking the phone.
i didnt experience this on my oneplus 5/6 or samsung / huawei devices having them decrypted.
does anyone know how we can get fingerprint / pin working without encryption?
i notice the phone is more responsive and snappy without encryption
Hi,
I have Mi 9 SE with global rom v 10.2.2.0(PFBMIXM).
When I go to system settings->Additional settings->Privacy->Encryption & credentials, it shows that my device is encrypted. But in the past on other xiaomi phones I owned there used to be an option "Encrypt Device with lock screen password" which is missing in MI 9 SE.
So, in the past the phone used to ask for lock screen password during boot and only then then system/data disks would be decrypted and phone would start booting. Now this is not happening because the phone is using whatever device default password it has for decrypting the device during boot up. So I have following questions,
1) Can someone with above version of global rom confirm that they also do not have "Encrypt Device with lock screen password" option?
2) Can we also confirm if China and EEA Roms are also missing these options?
3) Is there any possibility of somehow enabling the "Encrypt Device with lock screen password" because I would really like to use my password for encryption rather than some device default password.
Many thanks in advance for your help
There is no way doing this and it's this way on all ROMs.
