Hi,
I'm currently in the process of turning some Nexus 7 tablets into hand-held scanners that we will use with our SAP ERP system to carry out transactions related to inventory management. I was able to configure most of the settings that I needed to and have successfully locked down the tablets causing them to act directly as kiosk type devices (yah). I have one problem left and that is when I plug the barcode scanner into the tablet (via Micro USB) it automatically disables the on screen keyboard. I'm aware that the system recognizes the scanner as a text input device and that is why it disables the on screen keyboard. I found that I can go into the SettingsLanguage & InputDefault, and change the input method for the Hardware/Physical Keyboard to off which in turn allows me to use both the on screen keyboard and the barcode scanner at the same time (perfect! right?). They need the on screen keyboard to type in their credentials with but also scan material id's, batch number, etc. with the barcode scanner. However the problem it that whenever the scanner is unplugged or the power is turned off the hardware/physical keyboard setting goes back to on thus locking the on screen keyboard from being accessed. Since we will have the tablets locked down, we will need some solution that will automatically turn this physical keyboard value to off whenever the scanner is plugged in as the user will not be able to navigate to the system settings (nor would we want them to). I initially thought that I could edit the code to change the default value for this setting to off however after some extensive research I haven’t found where this setting resides or how to change the value. I also thought if I could use a tasker like program to automatically change the setting to off whenever a physical keyboard is enabled that this would also work but I have not found a program that will allow me to automate in the details that I need. Can anyone please shed some light on this problem? Does anyone know where the value resides in the API/Android OS? It there a program that I could use to automate changing this setting whenever a physical input device (keyboard) is recognized by the system? Has anyone ever heard of someone successfully integrating barcode scanning with any android tablets (specifically SAP)?
Thank you for your time!
Cory
hello,
I assume that you have input fields in your tablet screend and when you click it a keyboard shows up. I am also searching a similar application novadays and found out this app: barcode-scanner-keyboard-for-android. you can find it in the market.
Basicly it installs a replacement keyboard to your tablet and during input if you change your stock keyboard to this, you can both scan barcode then send enter command by keystroke or other commands. when you check the link you will understand what i mean.
enjoy.
I've noticed that Android 5.0 allows to change many system settings (enable/disable WiFi/BlueTooth/Autorotate/etc) on its Lock Screen without entering any password.
I hate this liberty.
Does anyone have any idea how to disable this feature?
I cannot find anything in settings.

I too cannot believe this was left as a feature... I was hoping that would be fixed in the final version.
Bump.
This is actually a security issue.

I agree but there's nothing in android. 3rd party lock screen is the only way.
a fix for this would be good, as anyone can just pick up your phone and change any of the quick settings without unlocking it.
So you would not be able to track the phone if it got nicked and someone just stuck it in airplane mode!

does it matter if airplane mode is in quick settings or the main setting? if they want to steal your phone and put it into airplane mode, they will do it regardless if its in quick settings or the main settings. its stuff that you yourself use often that will appear in quick settings. i personally think its a great feature.

But they should not be able to do it while the phone is locked. At very least we should have the option of what should be accessible without unlocking the phone.

even if they were not in the quick settings, you can still pull down the notification bar while in the lockscreen, and go into the main settings. so, everything there is available to any thief.

If i do that it prompts to unlock the phone
Heck, I'm not even worried about the security situation with this, I just want to disable it because I think it is extremely poorly executed!
It offers nothing that power toggles doesn't, and is not even configurable for what options are present. I never use auto-rotate, cast screen, invert colors, etc, and yet, those options are available instantly!

They can also just remove the sim card or turn it off.
What I am looking for, is for the only possible thing you can do, while the phone is locked, is enter the password. Is there a way to set that up? Not be able to toggle any settings at all or remove the quick settings(I am ok with the emergency calling and camera widget, since you can't access the pictures on the phone until entering the password). I know they could still remove the sim or power off the phone but at least it might buy some more time if your phone gets stolen for you to track it or snap a pic of the thief. It would be nice if you could also disable the power menu and volume buttons while on the lock screen.
For now, until other solution is found or developed, you can go to notification settings and in 'When device is locked' change the setting to 'Hide sensitive notification content'. This disables access to quick settings from the lock screen but also hides titles of notifications, so you will see the notifications for emails, texts etc., but their content will be hidden.
This doesn't work. Well, if you have root and xposed you can install "Advanced Power Menu" to control the power menu on lockscreen etc and with GravityBox you can control the items on the quick settings. But I still couldn't figure out a way to totally disable it on the lockscreen.
As I remember the "X posed" Module "Notification Mod" could do exactly this. Problem is: It seems that development is discontinued and the stable ver1.2 doesn't (on my lollipop custom rom) work on 5.x

I am seeing this in my new Samsung S7 edge... with finger print and password lock.... it is not there on S5 with finger print and password lock... its a silly feature... why would they turn it on ? My son just put my phone in airplane mode accidentaly.... and I kept wondering why no messages and calls for the whole weekend.... hate to think what it would be like if it happened to someone who was say, on a on-call emergency personnel or something like that.... no one would be able to reach out to them.... I guess now have to keep checking my phone every hour.... hahahaha... or maybe go back to using my S5.. if someone has a solution to this pls share... appreciate it.
No way to disable access to quiick settings on lock screen on unrooted Android M....
Try the Market anyway,
One solution for me on Android 6.01 was to disable WiFi, Bluetooth, Airplane Mode, Mobile Data from Quick Settings using Systen UI Tuner in Settings then downloaded Settings Extended app at the Market and moved all mentioned in SE's Notification Shortcut. Don't forget to enable "HIDE LOCK SCREEN NOTIFICATION" in Preferences which is the objective of all this anyway. So don't forget to ｃｌｉｃｋ this.
You can even disable everything in Quick Settings and instead put them all in SE Notification as Shortcuts. What's great about SE is that its Notification gets the icon color/shade/background color/color when toggled etc. perfectly in Android 6. Exactly the same. It looks like its really part of the Notification Screen except that there's that horizontal gap that separates the notifications and makes the screen fiddle faddle.
Try it anyway. It might be your only hope against lock screen vulnerability in unrooted Android 6.0 phones.

I have the same problem with my S7. Its weird that you cant change the wifi or bluetooth without unlocking the phone but when you select mobile data or airplane mode you can turn that off from the lockscreen so when your phone gets stolen, the thief can so easy turn that off that there is no way to trace your phone. Why do they even call this a smart phone while its so dumb?

I must apologise first, I’m not a nerdy-head about android, but I was thinking about my new phone (upgraded to A7) and your question is one that I sought out for answers.
In Nougat, I logged in as Guest and used a pin for the user so that a ‘guest’ can’t access the Guest account without my permission.
Then comes you’re question.
You can remove all the worrisome quick start icons from your quick settings (probably leave flashlight). Then use a 3rd party app (Notification Toggle is mine) which isn’t available to a user from a protected login.
As I’ve never had a lollypop viable phone I’m afraid another user might need to help you with a more detailed method for A5.
Hope it helps somewhat. As an old 8080 machine code programmer, it was always about solving problems and then working the bugs out. I'm not even sure how to post on these - socially thingy’s.
This issue it's still there in Nougat, so before it is passed on to Android O, we have to POPULARIZE this issue so they(Android developers) know how big of a pain in the ass it is. I'm posting the complaints to every forum, magazine, fan page, etc. When it's on the social media, they have to do something. This issue has survived because people don't want their friends to know about it, coz it's partly embarrassing...
Okay so this happened a few days ago and has still not been fixed. The problem is that when I go to unlock my phone with the fingerprint scanner witch is what I've been using since I got the phone. Scan my finger and it just keeps saying no match I do know the backup password and it unlocks the phone. But I have tryed to scan my fingerprint again through the scanner option in settings. It want me to scan my finger for verification as this does not work iv tried. I then go to enter the backup password to access the setting to change my lockscreen code swipe exc. When I enter the backup password it tells my the the wrong password has been entered. Now this same password opens my phone unlocks it just fine. But will not let my scan my fingerprint again or change my lock screen. Any ideas on how to fix this woth out a backup and restore? It's rooted so it's not big deal but I'd rather not have to.
Did a bit of research myself as i had the same problem, always remember to deactivate fingerprint scanner before making a backup (This didn't sound like your issue but just something to keep in mind). I found this post from another forum which fixes your issue.
You will be able to input new fingerprints into your phone from the settings menu once you have completed this guide:
Hahaha it's not a fix so much as a workaround. It removes your registered fingerprints without having to factory reset.
Ready? In recovery, navigate to /data/validity/ and delete "template.db"
This won't remove the lock screen setting so upon reboot the lock screen will still think you're using fingerprint... But your backup password will work.
I actually had to do a reset the only thing I can think of that happened was I had the finger print scanner as the lock on my phone before I rooted the phone. I'm not sure exactly but I believe that it deleted the "details" I guess that's the best way to put it. You know the way it makes you scan your finger in multiple times in different ways. I always used the same way every time thinking about it now I always had problems with unlocking my phone with the scanner I just thought it he scanner was total crap. But yeah I guess when I rooted the phone it did something or maybe I just didn't do it right the first time.
But the problem has been solved and the phone works fine the scanner is a lot better than I thought.

Give this guide a try for the fingerprint scanner if you wish to use the scanner. Always had issues with it till i found this and it has helped out drastically.

My issue is......while using the phone it jumps frpm what am doing then prompt me with the option to enter my backup password
Hey everyone.
So installed Microsoft's Next locker to see if it is a worthwhile replacement for the stock EMUI lockscreen (and because they recently added fingerprint reader support), however I have been facing some issues with disabling the stock lock screen, and therefore end up with the "double lock screens". The problem is that, when trying to set the "Password" under Screen Lock & Passwords, the "None" option is greyed out with the following notification: "Disabled by administrator, device encryption or credential storage."
I've had a look at this thread, and the solution that @RobboW posted there doesn't seem to work for me. First of all, the Huawei Unlock doesn't exist in EMUI 4.0 it seems. I did find a Smart Unlock feature (with a Huawei logo, hence the assumption that it is a successor to the Huawei Unlock feature) under Settings - Advanced Settings - Security - Trusted Agents, however disabling that did not work.
Further digging on the internet suggested that I clear the credential storage, however that didn't solve my problem either. Further than that I cannot see any of the two currently active device administrators interfering with the lock screen (I tested it to be safe, and disabling them didn't make a difference).
Has anyone had this issue before, or perhaps know of a workaround?
Cheers! :good:

Hi there, I know it's been a while but lately I faced the same issue and somehow found a solution. Hope it helps you as well.. Try this http://ministryofsolutions.com/2016/10/disable-screen-lock-huawei-devices.html
Does anyone else have issues with the separate app sound setting getting turned off? It's pretty damn annoying to have to turn it back on every time I reboot my S8+
On the note of annoying things at reboot, why does the phone require a password instead of your finger print, retina, or pattern if you have them set up? It doesn't make any sense to me, especially when it seems like either of the bio-metric options are much more secure than just a password.
Thanks.
For me it's secure boot that turns itself off. What's more interesting that you usually need to type in your password to confirm disabling secure boot but it doesn't ask for it.
Just wondering if anyone discovered a method to automatically enable this feature after reboot? Maybe something Tasker could trigger?
