Accidentally, I found that the Dell Venue 8 has a dialer screen. This screen can be used to enter "secret codes". The only one that I have found that works is *#*#4636#*#* (or *#*#INFO#*#*). This brings up a "hidden menu" with Tablet Information, Battery Information, Usage Statistics and Wi-Fi Information items.
There might be other codes that work on this tablet. I have not found any others that work.
To access the screen open the Settings app. Go to About Tablet and tap repeatedly on Software Version.
Debugging
Also if you go into settings and hit the BUILD seven times, you unlock the Developers option for USB debugging!

HELP !!!
I use a program that requires the screen lock on my SGS 2 is set with at least 8 characters. It is very difficult to have to enter the code each time the screen has been turned off.
My screen lock is disabled by the administrator and if I use "Select Device Administrators" and uncheck the administrator, then delete the program itself.
Can I with my rooted SGS 2 go in and uncheck the administrator by change in any of of system files, so I can get permission to disable the screenlock ???
( running Rooted SGS 2 with android 2.3.5 )
Can't you take it with your IT admin?
Is your company so big that you have to cheat the company security policy rather than argue with the IT guy about it? The IT guy has set that policy to preserve company sensitive data I assume. My company force me to have some screen lock, not sure how big so I used a 4 digit PIN to unlock it, and that's a small thing.
Notice that you may also tweak another setting: how soon after screen saver does the screen get loked. What if it was locked after 10 minutes and not straight after it shut down the screen? Not sure how to do that though.
Yes, the company security policy can unfortunately not change. Then I
must cheat a bit and try something else.
On my old SGS 1, I could use the "SGS info" and disable screen lock
But with my new SGS 2, "SGS info" does not disable screen lock.
So I must try something else now.
Super Cool !! I solved the problem myself today !!
Now screenlock is not get active, even with password enabled.
The solution on the Samsung Galaxy S II
Install app "SGS Secret Code"
Start the app and select "Power Button Settings"
Mark "Shutdown"
That's all.
Thx a million P.Bue
I have been searching for this quite some time...
Have a customer with a Samsung Galaxy Tab E SM-T560NU. It's running Android 5.1.1. My customer wants parental control filters put on because he can't stop himself from watching porn on it (planning on using Norton Family). Problem is, Android 5+ have this stupid guest account that lets anyone get on and use the device, bypassing any filtering or parental controls.
All the guides have told me to go to Settings, Users, then press the 3 dots in the top right to disable guest account creation at the lock screen. Even Norton's instructions say to do this. But this tablet doesn't have 3 dots. It doesn't have a menu button. I tried holding down the program switch button, and it wants to do split screen apps.
I got desperate, so I rooted the phone. Tried a half dozen SQLite editors, followed the instructions at reddit. com/r/Android/comments/323l36/android_5x_how_to_disable_guest_additional_user/ (skipping steps 2 through 4), and it just won't save the change of guest_user_enabled to 0. I also installed ADB, ran ADB Shell on the PC, enabled USB debugging, approved the ADB connection, and ran "settings put global guest_user_enabled 0" to no effect. Running "settings get global guest_user_enabled" shows the value as 0 instead of 1, but reaccessing the SQLite DB shows it's still 1, and I can still get into the guest account from the lock screen after deleting the guest account. I also tried "settings put global guest_user_enabled 0" after running su to no avail. And I did restart the tablet after running the command. Once I did get behavior as expected, clicking on the person icon in the top right brought up the contact card instead of the menu to switch users, but after I went into settings and clicked on guest, it undid it.
So. Long story short, tl;dr, is there any way to disable the guest account?

Bump - Anyone?
Does anyone have Enpass working on Android 10? I have encountered two problems.
First, I go into an authentication loop trying to sync with Google Drive. Authentication is successful, then I am sent back to the "Pick an account to sync with" screen. I can get around this problem by copying Enpass settings from another phone running Android 9, then I have the second problem - autofill does not work. Autofill prompts me for a PIN, asks me to select the item, then returns to the login screen without filling in the user/password.
Possibly the autofill problem is caused by copying the settings from another phone, but I can't determine that until the authentication loop problem is fixed.
Enpass version 6.2.0.245
Android 10 build # QP1A.190711.020.C3
Problem solved. First, if the "Don't keep activities" option under Apps in Developer Options is enabled, disable it. If that does not fix it, disable Developer Options and test. Re-enable Developer Options. It should still work. Some of your developer options will be disabled, so you'll have to re-enable them.
Just got this treadmill and it’s basically a 23” android tablet connected to the treadmill. Thanks to another thread here, I managed to get into “privilege mode” which allows you to access the android shell and settings. For others looking for this info, instructions to get into this mode are
1. In the ifit app go into settings
2. Tap on maintenance
3. In the blank space below the maintenance settings, tap rapidly, around 10-20 times
4. “Privileged mode” will show up as a message at the bottom of the screen
5. Swipe up from the bottom edge and you will see the android taskbar, tap on the circle and you will go to home, now you can access android settings
I do not know how to turn off this mode. However it seems to be ok, only difference is that the treadmill will boot to android home, then launch the ifit app, which may be disconcerting to some SO sharing the device.
Now on to the hard part, it’s running 7.1.2, so I assume after going into settings and turning on install from other sources, I could side load. Nope, browser crashes every time when I try to download something, eg apk file.
There is no user accessible USB port, any idea what I should do or side load stuff like Netflix? YouTube on the browser seems to work though.... any help here would be much appreciated!!

Wow. I have the 2017 version of the 2950 that has Android 5.1.1 along with an external USB A female port and a (useless) female HDMI out port that should allow hard wire video / audio to a nearby HDMI input capable device.
I, too have privleged mode active per a tech support call a while back. Anyway, let me say that a while ago I nearly bricked mine trying to sideload a few APK's, so be ready to assume the responsibility for anything that may happen. You should be able to get to the browser in the OS and go to Google.com and sign in... this will let you get to Drive and Gmail and grab any APK's you've parked there from a PC or whatever?
Hey, do you have WiFi for 2.4GHz only or maybe 5.8GHz as well? Just curious, not that it will help me at all... I have a USB-A to Ethernet dongle that refuses to work with the console's USB port . My 2.4 connectivity is garbage.
This is ironic. I opened the built in browser and was going to sign into google to grab an APK of Google Home... all of a sudden I see Privilege Mode Removed (or something like that) pop up and the iFit app stared up. Now the 2950 fires up quicker like it did when new. SO bizarre!
Hi there XDA. Been a while and hope everyone's been fine. Need some expert help and hopefully some resolution can be found.
I have a Note 8 that was dropped. Belongs to a family member and was taken to me as the resident tech to get things off. I managed to get all FILES copied off the device, and they no longer need it however...being how I am, I'd like to try and recover EVERYTHING from the device. All notes and such - especially as some of these things were used for classes. However I'm stuck,
Screen is totally black and was responding to finger touches before - not doing so now. Unlocking the device isn't an issue as I can do that using the stylus or a USB keyboard through OTG. I'm able to navigate using the USB keyboard and get into certain settings, but without actually seeing what's going on I don't know what is stopping certain actions or why they don't work.
The current goal is to get talkback working so that it can read to me the various options. If I can get it on then I assume there will be smoother navigation - however....
I got my hands on a Note 9 and used two USB keyboards with OTG simultaneously to try and mirror the actions. Attempts to enable talkback failed. On the Note 9 the option comes up and you hear when it asks to be enabled, but on the damaged phone you never hear it. This is a tedious process which involves:
Attaching USB keyboard.
Using shortcut keys to get into the apps menu (ALT+A).
Navigating to SETTINGS.
Typing in the name of the area I need to get to.
Pressing the arrow keys the appropriate number of times.
etc. etc. etc.
Finally when it SHOULD be at the talkback option, nothing is read back to suggest it's enabled. Holding the VOL+/- keys for 3 seconds don't work. Inserting a SIM with data then using voice to "turn on talkback" results in a response: "I can't change talkback yet."
So now - I'm at a loss. Once I'm able to turn on USB debugging I should be able to connect to my PC/laptop and mirror the screen. From there all navigation should be easy - but following what is seen on the Note 9, it doesn't work. So I can't enable talkback and I can't enable USB debugging. I'm also not 100% sure where on the screen the prompt would appear - so unplugging and replugging then guestimate tapping have not been successful.
So far I can use it like an expensive USB drive, but I'd like to get all things off, test the functionality otherwise, and then factory reset before giving it away or selling it. Not ready to buy a screen as the cost is the same as buying a used device.
Well - that's everything. Hopefully someone can assist. I can post the exact steps after someone replies, but let me give a quick rundown below. If you have one you can try with a USB keyboard and see where it gets you.
Unlock device with PIN.
ALT+A
UP x2
Type SETTING
ENTER x3
UP x2
ENTER
Type TALKBACK
Enter x3
Down......can't recall. Think it was x2. To the voice option.
ENTER
DOWN
ENTER
DOWN
RIGHT
ENTER
The last bit should select the ALLOW option and ultimately enable talkback. But for some reason it doesn't. Nothing is heard. For the USB debugging it's the same thing except at step 8 it's "USB debugging" then down like 9 or 10 times to get to the option - then enter - then right and enter.
Nothing has worked so far to blindly enable either talkback or USB debugging. So any help is appreciated.
I'm hoping there's some file I can copy directly to the file system, or something I can manipulate on the file system to enable either of these features, but I won't hold my breath. No idea whether or not this will work, but hopeful all the same. Looking forward to replies and thanks in advance.
