Device encryption - Nexus 9 Q&A, Help & Troubleshooting

On by default. Is there a way to disable encryption?

Also for those that use encryption can it be made to ask for a pin at boot but pattern lock for normal unlocking?

It is encrypted....
I didnt notice that. I wonder why?

Why do you want to disable encryption?
The Nexus 9 apparently uses a hardware-backed key store (based on ARM TrustZone technology), which is partly why its able to enable encryption without a passcode. It also seems to make use of ARMv8 AES instructions, which allows fast and energy-efficient crypto operations. Basically, there shouldn't be a performance or battery hit.

[Q] How to disable GPS warning on Android 2.3.4

In 2.1 there was no warning when enabling GPS, but now it is. And for that reason all widgets that enable GPS lost functionality because, that action cannot be done with one click. Is any way to bypass or disable that warning?
if i am not mistaken this issue started with GB.. not only it renders all widgets and toggle into less useful thing to have in our phone, it also renders some anti-theft apps that requires automatic activation of gps radio to work.
I dont know when is started, but I know that is very bad "feature" and hope someone will find way to fix or bypass. If we can root device I am sure there is way to disable this warning.
I just leave it on all the time.
As long as no app is using it there is no battery-drain afaik.

[Q] Device Encryption wiht Pin

Hello Guy's,
we are testing the S3 for Enterprise use. We also want to use the Device Encryption Feature.
When i want to Encrypt the Device it Says i need a least a 6 Character long Password with one Number in it for the Sreen lock.
Thats maybe more Secure but a little to complicated for Every Day use.
Samsung E-Mail Support told me that is it Possible, to encrypt the Device with Pin Screen lock only.
But if i have a Screen Lock with Pin the Device won't start Encryption.
Can Somebody confirm that, or tell me what i'M doing wrong?
Basicly on my HTC Legend with ICS Custom i saw that PIN Only Encrpytion is Possible on ICS.
Regards
Steven
First off: encrypting with PIN is as secure as not encrypting at all - you really don't want to do that if you're not only using it as a gimmick but to actually keep your data save and secure.
That said, I think it's possible the same way as I did it on the S2.
With a custom app that triggers the encryption w/o forcing you to set a specific password first.
// EDIT
Connecting to an Exchange Active Sync server with a security policy set up to your needs might work as well.
Hello Hellcat,
BIG thank you for your reply. Setting a Active Sync Policy with 4 Chars allowed me to encrypt with pin.
i didn't know that Active sync is that powerfull out of the box.
The Interesting Point is that the Settings of the mobileiron device Managment Software didn't work, although i had the same settings.
I know that a 4 Char Pin ins't really secure, but it will still lockout 95% of random people how find a lost device.
And theres always a trade off between security and usability.
regards
Stefan
Kinda Sorta Similar
I normally just lurk and observe the talent around here, but I had to register to voice a kinda sorta similar issue. (watched noob video)
The balance between security and usability with the standard encryption scheme seems problematic. I'm pretty sure I have an original gameboy that can crack a 4 digit passcode, but I don't want to have to enter 20 characters every time just to unlock the screen.
I want to be able to have a strong password on boot, but have a separate weak password lock screen. I think that would fix the problem of usability while maintaining strong security. Is there anyway to do this?
Are there any groups or projects that include or work on user friendly encryption?

[Q] Credential storage - PIN

Hi,
I have just upgraded my Note2 to 4.4 - clean install. I have mostly set it up, when I noticed i requires PIN for storing a VPN connection or a CA certificate. However I was used to the gesture lock screen, but pin makes it harder to access while driving and other activities, so it's definitely not appreciated.
I have read some forums, and the general answer was to simply clear the credentials, but I want to keep my CA certificates, and my VPN connections, I just don't want this kind of security. I have also tried this: http://forum.xda-developers.com/showthread.php?t=2253123 but with no success - Sqlite manager can not find table locksettings (the other two are shown).
So, can anyone help me with this? I am definitely not using PIN, I'd rather set up some enormous timeout, which really is questionable from security point of view, but still better for me than typing that st*pid PIN each time.

Encryption

Has anyone enabled encryption and can comment on performance?
I activated on device (not sdcard) and didn't notice changes in daily usage. But i'm not running load tests
Longer to boot due to additional step at startup, but except that, I use it the same way
I use FDE on my Z5, performance is flawless, no difference to non-FDE use.

Activate accessibility option and secure start at the same time

Hi all,
apparently this seems to be a known bug (feature) of the S9, at least I found several reports on different forums, however without any solution so far.
The problem: It is not possible to activate both, the accessibility option for an app (e.g. for Nova Launcher, Tasker or BixBye) and the secure start / secure boot option (official name might be different - I'm talking about the option that requires you to enter your PIN / passphrase before your phone boots).
Whenever I try to enable one of the accessibility options, secure start is switched off.
Is there any workaround for that?
Thanks and cheers!

/edit: I forgot to mention that I never experienced this problem on my S7.
On my AT&T S7 Edge, and my AT&T S9+, I just go into the Security Settings and turn Secure Startup back on. It warns that the accessibility services won't be available until the phone fully boots.
