[Q] Secure Viewing: Password Required To Enter And Exit! - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I'm looking for a way to handle reasonably secure documents. The idea is: I open the app/document, and the viewer has a few minutes (doesn't have to be timed). In order to give a reasonable amount of protection to other data, in order to leave the app, a password is required. So...a password is required to open the app, and to close the app.
I can encrypt the device to avoid restart and external exploitation. Extra Brownie Points if I could have the app open upon turning on the screen, and after leaving the app, you're sent to the lock screen where a password would be. In this scenario, this "mode" or app requires a password to enter the app, and if they try to access the rest of the device by exiting the app or pressing the home button, they're brought to the locked lock screen. I suppose this particular one would protect against the user simply restarting the device as well, but it would let me know that they tried to exit the app, and might have tried to access your data.
Also, while I'm not so worried about USB exploitation, it'd be nice if there was a way for me to turn off USB recognition.
I suppose this could be accomplished via some combination of an app locker and lock screen.
Just as well, it'd be uber cool if I could have this app be a secure, password protected launcher protected that only shows this one file or one app.
Maybe some type of kids-mode? Or store mode? But I want to protect against force closes, app closes, restarts, and turning the screen on and off.
If you're having difficulty imagining the scenario, just imagine that you wanted to show a PDF (perhaps proof of insurance) to a police officer, but you didn't want them looking at your photos or other text messages Like these guys:

SO....how on earth do I do this?
*EDIT*: I suppose if I could password protect a launcher, I could then install an app that password protects all appslauncher, and then hide all apps but one...but it would have to require a password to change the launcher or enter the settings app. I'd then have to figure out a way to protect the device.... and hide all files and apps except the one document and the one app, sandbox style.

For pattern lock: Settings > Location & Security > Security Lock
From there you can do a passcode or the pattern. I personally use pattern because it can replace the slide to unlock all together while keeping it secure.
I got the pattern lock....but what about adding a note or your personal contact information, thats whats missing...thanks
If there is a way, I haven't found it. I know you can do it on rooted devices, depending on how the rom is set up, but as far as the droid x, I haven't seen a way to do it. You can download an app from the market that will call your phone if you lose it. Also there are apps that will find your phone on GPS. I know this isn't really what your wanting to do, but it will help you if it gets lost.
after many hours on the net I found the answer. you get this by installing the antivirus program from the apps market. you change the "this phone belongs to:" by going to the antivirus program and pressing the menu button form there go to settings, then remote management and finely lost message. you can change the whole message

That's just specific to that app. There is no way on the stock rom to set this information you are looking for. Just add a contact called Me to your contact list. That way if you lose the phone, somebody may call you (If they don't keep the phone)

Too much work for something too small I think.
One way is to update your wallpaper image to have the text you want (using your favorite image editor). Of course then it'll show on the normal home/launcher as well. But a short "Belongs to John Doe, (555) 555-5555" towards the bottom-center should work.
just found WidgetLocker Lockscreen. I havent tried it yet but I guess you can put widgets on the lock screens so I can put a note there with all this information...worth a try

how to get a lockscreen with password and still be able to access apps with no pass?

I apologize in advance for the title, seems confusing but i'm unsure how to word it better.
We Share an A501 at home for a few apps and games.
Unfortunately all my info is in there and since Android doesn't support multiple users I thought a good way of doing this would be to use an alternate lockscreen (Like Widget locker) add a few widgets and apps in the lockscreen for everyone to use.
But you need to enter a password or pin to enter the device completely.
I've tried doing this with widget locker, but the problem is when I start an app from the lockscreen shortcut I get the Pattern prompt.
Any idea whether this is feasible?
Thanks
There's an app called seal that puts a password on individual apps. You can have a standard lockscreen, and just protect the apps you don't want anyone using.
probably would be a lot of hassle as I'd need to protect 10+ apps and have to type the password myself everytime.

It's actually not that bad. I use it to prevent my kids from opening bank apps and other non-games. I have it set up to prompt me for a pattern not an actual password. Try it!
When you enter the password for an app any other protected app can be run within X time. after that you have to put the password in again.
I use this on my cell phone.I lock SMS sunk and a wifi tether app.so that when my son uses my cell I still get my textessages he tries to turn it off so my tablet will not get his text.teenagers grrrrrrrrrrrrr.

[Q] Unlock screen using tasker?

Hi,
since I have finally gotten NFC on locked phone to work on 4.2.2 rooted stock ROM, I would like to add a task that unlocks my phone in combination with an NFC tag (which I placed in my car dock).
Unfortunately, I cannot get it to work, whatever tool I use.
- Security settings, especially "clear password" oder "keyguard/patternlock off" don't seem to have effects.
- Widgetlocker can be reached with an intent, but only brings me to the pin screen instead of the desktop.
- "Unlock Keyguard Ad" takes me to the desktop but still seems to keep some kind of keyguard in the background that pops open when I e.g. open tasker.
The problems with "clear password" might be connected to the fact that my device in encrypted ...
So, any idea how to automatically unlock an encrypted Nexus 4 with PIN on stock firmware?
Update: Don't know what went wrong the last time, but now "keyguard off" does have an effect: The same as "Unlock Keyguard Ad". I get to the desktop, I can start apps, but if if I select e.g. tasker from the system bar, I am prompted for the password. Cannot see a system here ...
Also, "clear password" now has an effect: It sets the PIN to empty, but I am still prompted ...
Same issue with password on encrypted device
I was thrilled to find this thread because I'm facing the same issue of having trouble disabling my lock screen with an encrypted device.
My excitement turned to disappointment when I realized it's been over six months with no response. Did you find a solution? Does anyone have any insight into the best way of preventing the need to enter a password on an encrypted device?

Fingerprint for just Apps not Unlocking Phone

Like the title says, is there a way to just have fingerprint be used to get into certain apps like all your banking etc and just be able to hit the home button to unlock or swipe to unlock the phone. I'm new to it and not a fan of the spot of the fingerprint spot (who is right?) came from a Pixel XL and just cant get use to it. So just wondering if there is any option like that so I dont have to remember as many password variations to get logged in. Thanks
use either no lockscreen or a slide to unlock lockscreen(lock screen and security > lock screen type), and use the secure folder app to store all your sensitive apps and data.
or you can configure smart lock(lock screen and security) and use a secure settings app to set the lockscreen timeout to more than 24 hours, and use secure folder for sensitive data and apps.
any half decent banking app should already have protection through a pin and/or fingerprint so you shouldn't need secure folder.
I'm using the 2nd option since it also lets me use some of my phone's secure features that require a protected lockscreen.

Disable Magazine unlock

There's a category called "Screen lock style" in the Screen lock & passwords section of the phone's settings.
How can I add other screen locks to that list? From my limited experience, if I download another lock screen from the Play Store and enable it, after unlocking my phone with the new lock screen, it still opens the phone to Magazine Unlock, and the newly downloaded lock screen does not appear in the Screen lock style list.
My ultimate goal is to disable Magazine Unlock entirely, because I'm using the Gravity app to unlock my phone.
My phone is rooted. Hoping for a solution that doesn't involve switching ROMs.

Hmmm.... are you running the stock ROM? I appreciate the response, but there is no such entry in Developer Options.
Yes, I am running stock b180 rom. I thought it was in b170 too but not 100% sure. See attached pic.
Disabling screen lock is problematic for me, I believe because of huawei's encryption settings or because I use an sd card for primary storage. Ive googled around and played with a few fixes, but no luck so far..
Fwiw, there is no such thing as replacing your lock screen.. all you're doing is disabling your devices built in security and trusting a third party app, every one of which I've tried basically amounting to adware at best and spyware/malware as the norm. I'd be very careful running those sketchy apps..

It appears I looked right passed that, because it's grayed out on my phone. It says, "Disabled by Administrator, encryption policy, or credential storage."
I went to Advanced Settings > Security > Device Administrators - and disabled the two apps with access, but I don't know where to go for encryption policy.
Trusted Credentials is also located in Security, but I don't know what entry I'm looking for there either.

Gravity isn't a lock screen, it's an app that wakes your phone, based on movement and tilt, without having to press the power button. I don't care about security. If my phone gets stolen, I'd rather remotely disable it from the Find My Device website than put up with constantly entering passwords and pressing buttons every few minutes. I want to enjoy my phone. I compare it to the concept of having to enter your computer's password every time you pause Netflix or walk to the kitchen and back. The security level is ridiculous. Most would-be thieves aren't going to get anything from my phone before I remotely disable it. I don't use banking apps or store important passwords on the phone. The most they'll get is my contacts list and access to my music.
Do this to disable your lockscreen password, assuming your phone is rooted:
Rename both files (e.g. add .bak to filename) :
/data/system/
gatekeeper.password.key
and
gatekeeper.pattern.key
You can easily do it with TWRP File Manager or any root File Manager.
Then reboot the phone and you should not be prompted for the phone password or pattern.
Don't forget the thanks button if this helped you .
You take full responsibility for disabling your phone's lockscreen protection - e.g. losing all your bitcoins hahaha
Awesome! Got so fed up trying to disable my screen lock, ended up just wiping the phone, lol

In the security settings you should be able to clear the encryption policy or credential storage but that does not allow you to get rid of the lockscreen period but what I stated above allows you to clear the password meaning to take away the "Disabled by Administrator, encryption policy, or credential storage." Also if you can't find the option above goto backup and reset and reset the system settings you may have to reapply your EMUI theme and your settings but I usually use Next Lock Screen being a suggestion!

My lock screen is completely disabled by turning off "screen lock" in the developer settings. That is when i turn off the screen or the phone goes to sleep, i simply tap the power button and i am on my home screen without having to swipe or enter any passwords. i did delete magazine unlock folder, emui folder and theme folder in the system folder of the phone. not sure if that makes a difference though.
"My lock screen is completely disabled by turning off "screen lock" in the developer settings." isn't possible on my phone because it's grayed out. I don't recall what led up to it getting grayed out.
The solution I posted about renaming files is the only working solution I could come up with for my case.

I just wiped the phone and re-installed b180 stock from CLS (thanks cls!!). Screen lock toggle is available. I did not setup google account or att transfer at startup. I previously unlocked my phone to use for T-Mobile. On another note, I have been trying to figure out how to get Volte calling on T-Mobile. Under the specs of the phone, it is suppose to support it but there is no setting for it by default. But, i found if i delete the ATT folder in the "cust" partition, the toggle is now in the settings. Haven't tested if it works yet though. Ive been trying to get this phone as close to stock as i can. Ive deleted emui folder, themes folder, watermark folder, magazine unlock folder, cdrom folder, most huwaei apps and all att apps. I feel like the phone is snappier now.

Those files do not exist on my phone. I am rooted, I have TWRP, and I also have the paid version of ES File Explorer, which is granted root. I did a full search on the drive too, found nothing.
To ensure we're all on the same page, I do not have a lockscreen password. Magazine unlock is a screen you see when you wake your phone, and you simply swipe up, and you're immediately taken to the home screen. I am not attempting to disable a password. I am trying to disable Magazine Unlock. The screen that shows random pics upon waking the phone.

I was hoping to not have to flash the phone. It may be my only option unless someone else understands how Magazine Unlock still works despite the fact that it's folder has been deleted from the System directory.
Have you tried disabling magazine unlock in the emui theme settings? Perhaps try the stockify theme, free on the play store?
Also, do you use an sd card for default storage?
I'm using a different theme, have internal storage as default, and still can't just select swipe to unlock (unless I rename files I posted about).

Your typing got a little messed up there at the end ("and still have can't just select"?). Not sure what you're saying, but I have removed the files you suggested, and I still must swipe to get to the home screen. I want to only have to press the power button to wake the phone, and then go directly to home. No swipe.
Corrected to "I'm using a different theme, have internal storage as default, and still can't just select swipe to unlock (unless I rename files I posted about)."
The swipe screen is there for protection in case the phone is in your pocket. I don't think you can avoid it as it's a safety feature.

I have magazine unlock disabled, no swipe screen at all, thoughall options to disable are still grayed out. I don't recall doing anything special, I'll dig around a bit later.
