General :: How To Change Disk Encryption Password Keyboard
Mar 5, 2014
I set a password to encrypt the disk on my N4. When I reboot the phone it ask me a password with a standard keyboard.
My question is : can we change this keyboard for another one or at least its orientation?
the cause is that my screen is broken on the lower right coin and it block the "Done" button. annoying...
The TWRP keyboard to decrypt the disk should be fine (its "done" button is larger enough)

I am running Android 4.1.1 on a Samsung GT-I9250M Galaxy Nexus.
Third, I have two carriers: a Straight Talk Unlimited Prepaid SIM (United States GSM/HSDPA) & a Claro Prepaid SIM (Honduras, GSM)
1) I installed the Straight Talk SIM in the phone.
2) I installed the battery in the phone.
3) I powered on the phone.
4) I enabled full disk encryption, choosing an easy-to-memorize password.
... over two weeks, i successfully decrypt the phone on boot 30 - 40 times with the password ...
... then i travel to honduras and purchase a Claro SIM ...
5) I powered off the phone.
6) I installed the Claro SIM in the phone.
7) When prompted to "type password to decrypt storage" I enter the correct password.
8) I am prompted to "try again."
9) I enter the correct password.
10) I m prompted to "try again."
11) I powered off the phone.
12) I installed the Straight Talk SIM in the phone.
13) When prompted to "type password to decrypt storage" I enter the correct password.
14) I am prompted to "try again."
15) I enter the correct password.
16) I am prompted to "try again"
I have tried booting with the Straight Talk SIM, the Claro SIM, and with no SIM. I have tried removing the battery. I am able to boot in Recovery Mode. However, performing a factory reset is not a viable option for me. I need to regain access to my phone. Why would the encryption key be altered by the SIM change? And wouldn't reinstalling the Straight Talk SIM be enough?

I have a Google Nexus 4 (rooted, of course) and I'm using the native phone encryption.
There is some information that can be found, revealing that google uses the native linux dmsetup tool for this.
Now, just in case anything goes wrong, I'd like to have a backup of the encryption master-key,
that I could use to restore the dm-crypt header.
On a normal linux system, this would be easy, only one call to dmsetup and I'm done.
However, I just can't find any info to do this on android.'
The UI doesn't offer this option (as is to be expected) and I just don't know how to do it by using adb.
I've opened a root shell session and tried some commands (dmsetup, cryptsetup, some calls to "vdc cryptfs", etc...), but I just don't find a way to do it.

I recently received the OTA update to my Eris and am loving the new interface. However every time I want to unlock my phone I am now required to enter an 8 digit password as opposed to the screen pattern I was using prior. From messing around I realized that this is due to the fact that my company's exchange account requires SSL encryption and therefore requires the password be entered to unlock the phone. My question is whether there is a way to keep my email but only require the screen pattern to unlock my phone? I know iPhone users at my company that are still fine entering their 4 digit code so have to assume we should be able to do the same.

I am developing an app that uploads files to an FTP server, and the app will have the ftp user name / password in the code. I'm investigating making the FTP user name and password as secure as possible (including an encrypted value for each in a strings.xml and decrypting in the app when it needs to connect to the FTP server).
My concern is this is not actually secure at all, it seems someone could unzip the .apk, decompile it, view the strings.xml and java code that decrypts it - and thereby obtain the ftp login info.
So my question is.. am I approaching this wrong way? Is there a standard method of ensuring passwords that are hard coded into an app can be secure? (note - in this case this is not a password a user of the app would enter, the FTP password is universal to all that install it so it is included in the app).

My wife has a D3, tonight she got a pop up warning her that her handset password will expire in 14 days with choices to remind her later or change the password. I've never seen this pop up on any android phone we've had. She does use the native Email app on her corporate account, so this may be due to that. I usually use Touchdown, so my phones haven't needed password protection for unlock.

I don't have my phone encrypted but I always have it password protected. I updated my Droid RAZR MAXX HD to KitKat 4.4.2 and discovered Swype was no longer bundled with Android. Straight to the PlayStore to get Google Keyboard (aka the old familiar Swype but significantly upgraded). As I had configured previously before the KitKat update, I had Swype as my default keyboard and all other keyboards disabled. So I went to settings disabled the default keyboard and enabled Google Keyboard and Voice Input. Later I went to use my phone and was presented with the expected login screen but saw a spinning red microphone with "Speak Now" and "Waiting for results". No keyboard. Tapping on the red microphone did nothing. Calling the Droid from another phone allowed a keyboard icon to appear to the left but tapping it did nothing (since it was disabled).
It appeared to me after research for several hours most people had not disabled their Default Keyboard and could recover from this. Since I had disabled mine, I have concluded that mine was bricked and left with only a factory reset.
In conclusion, Google Keyboard still has some bugs if it can't handle the login screen. This seems like a precondition to releasing this keyboard software to the community.

I'm new to android but just used the guides at this forum to root my LG Optimus V. I was wondering if now that I have root there is a way to install a boot password similar to the one I have on my computer. Before it loads the operating system, the BIOS asks for a password. Is there any similar functionality for android?
Also, is this possible on other devices even if it is not on mine? It's one of my favorite laymen security measures.

I just received my Xperia mini and I'd like to change the keyboard to "landscape keyboard". The user manual says that I have to change the settings to auto rotate for the keypad to function in landscape. I've done this but I still don't have it.

Enabled native encryption on phone and SD card. Phone took a dip in the ocean. Files on the SD card need to be decrypted, and none of the posts I've read are user friendly to a person with almost nill Crytpo experience.
I understand native encryption uses AES128, but I haven't found an explanation or program that will decrypt individual files.

If you enable device encryption on devices with external sd card, the external sd card always remains unencrypted. As you cannot really control for every app where to store its data, you have some of your app-data on internal sd (encrypted) and some of you app-data on external sd (encrypted). To me this seems to be a security hole, concerning device encryption. why cm team does not include encryption for external sd cards, like some oems do? They put so much effort in security features and on the other side they leave parts of the local storage encrypted?

Any way to revert back to a gesture-based lock screen after enabling encryption on my LG730 with android 4.0.4. I ran the SQLite queries (had to pull the DB and edit on my PC, then push it back), generated a gesture key and pushed it to the phone, restarted and... no dice. The lock screen is still asking for a password to unlock it.

I have a tablet NaviaTec, running ICS. Google doesn't support, because this tablet is not so popular cuz it's very cheap. Sometimes when I charge it overnight, in the morning I get Encryption unsuccessful screen. I read 5-6 different threads but all are different methods for different devices.

I have a Galaxy S III [International Version] and I'm running Paranoid Android [Based on CM 10.1]
I have busybox installed as well as root access.
I want to change the font of the Stock Android 4.2.2 keyboard and the default bold font of all the widgets on the launcher homescreen.
I have no clue which font maps to which so I simply went to Font Installer's preferences menu and selected any font with a "-bold" suffix to be replaced. All I ended up with was a boot loop.
Or is there something in addition to this that I should be doing before attempting a reboot? And what font am I actually supposed to change?

But windows phone keyboard has this great feature, after writing your text or message. You can then go back through the whole message just tapping on misspelt words once and it will highlight the whole word and give you suggestions that you can pick from.

When I go to system settings -> security -> encrypt phone, with phone fully charged and plugged in and a suitable PIN set, the phone reboots back to lock screen but does not appear to do anything to actually encrypt the phone. After reboot, the option remains looking identical in the settings menu. No error messages or the like.
The lock screen works fine (PIN required), the PIN is suitably long, everything is updated, etc.
I'm not sure what the issue is. I rooted & changed ROM immediately on getting the phone (it's new), so I don't know whether it would've worked w/ stock bootloader / rom / etc.
I'm running:
Nexus 4 (android 4.2.2)
ParanoidAndroid 3.65 (pa_mako-3.65-20130712 + pa_gapps-full-4.2-20130710)
TWRP bootloader (openrecovery-twrp-2.6.0.0-mako)

I'm on gs2 I9100 cyanogenmod 9 and can't find a solution to encrypt internal databases like sms, call logs, contacts... ( so in /data).
No problems with documents in container created by luksmanager. But i wonder is it possible to make a sort of preboot script who mount after correct passphrase a luks container who is symlinked in /data ? Because android ics built in encryption installation stop at beginning.
Is there now new method or app to encrypt full or partial phone? Maybe new encryption function or improvement in JB? Pattern/face unlock fixed?

So I screwed up and lost the passphrase for TB encryption. I have a good working android backup with all the apps+data that I would want to use for my next rom flash. The problem is when I go to TB and disable encryption on my good backup it doesn't allow me to restore the data when I flash a new rom. is there a way to completely remove TB and all of it's app data so that I can start from scratch with TB in order to good unencrypted backups of my apps+data without completely formatting my SD card? I'm stuck on my current rom setup.

I'm interested in encrypting my phone (rootbox 4.2) including the external SD Card (if that's possible..?) but i need to know if you do it, then let's say you take that sd card out of the phone and plug it in your pc, how do you access the data? And is that still impossible to unencrypt the phone after it was encrypted (i mean on last android versions)?
