The Linux user IDs that Android uses to isolate apps from each other are completely unrelated to user profiles on Android 4.2 tablets. In Android, each app gets its own directory for saving data. The Linux user ID system is used to make sure apps can't read each others' data. But all these data directories are inside one directory on the filesystem, /data/...

I attempted to get VNC options working, but they're all buggy. In particular the keyboard mappings and clunky and the screens never seem to render correctly. I even wrote to an author offering money for improvements but never got anything back. Teamviewer 8 is the only solution I've found where it actually works the way it is supposed to (i.e. seamlessly)....

The Virtual Tablet app is free on the Google Play Store. It works with some flaws but overall good. See the developers site for more information

With Kitkat your chances for a "complete solution" without rooting are pretty much zero: the Android project has definitely screwed up here. No apps get full access to the external SD card, which rendered a lot of them unusable: file managers: you cannot use them to manage your external SD card. In most areas, they can only read but not write media apps: ...

The manufacturer is trying to help you. Walking around taking photos with a tablet makes you look like a twerp, so they try to discourage you by not putting a good quality camera in there. That might be a slightly silly answer, but it's not entirely untrue. Taking photos with your phone is really popular these days, because you always have your phone with ...

I had the exact same wish as you, and I eventually found a solution I was happy with. It does not solve it in 100% the way you had envisioned, but let me see if it helps you. At first I was thinking to use the Android device as a remote desktop control (for example, via TeamViewer of Chrome Remote Deksktop) for my computer, and then open drawing software on ...

Your device will have a little magnetic sensor hidden under the display that can trigger the display to turn on. A small magnet lies embedded directly under the surface of the smart cover and lines up with the corresponding spot on the device. The device detects the removal of this magnet when opening the cover and turns the screen on, and can also put the ...

Solution (for flashing Qualcomm based Android devices) This seems to be an easy, fast and reproducable solution for flashing Qualcomm based Android devices (tablets, mobile phones), so it should not be limited to my device type. You should espacially read on if you have troubles with flashing an Qualcomm based Android device with tools like QcomDloader, QFIL,...

I had the same problem and had to try out a bunch of apps. In addition to what you were looking for, I was also interested in the possibility to add comments during the presentation using the s-pen of my galaxy note. All the apps listed below support full page view, so there are in principle an options for presentations. Moon Reader Pro This is an ...

The second user will have to explicitly install the wanted app (in your example: Facebook) – as otherwise all accounts' app drawers would be cluttered with a bunch of apps not wanted by everybody, except for those who installed them. But if the app already had been installed before by another account, it will rather be a "fake install" (i.e. it appears as if ...

From adb shell: am broadcast -a android.provider.Telephony.SECRET_CODE -d android_secret_code://<secretcode> Where <secretcode> is the code without the asterisks, e.g., 4636. This is more effective than the DIAL action because it's direct and does not rely on the dialer to parse the code and fire the secret code intent itself. (Some dialers ...

I honestly thought that only one device could be connected at a time using Bluetooth. In an attempt to prove my point I tested connecting multiple devices simultaneously to my Samsung Galaxy Tab 4: Sure enough I was able to stream music to my Milwaukee speaker while using an Apple mouse and keyboard- all connected at the same time. Granted, there are ...

There are at least three ways of doing it. Programmatically by starting an Activity with Intent.ACTION_DIAL: String secretCode = "123456789"; Intent intent = new Intent(Intent.ACTION_DIAL); intent.setData(Uri.parse("tel:*#*#" + secretCode + "#*#*")); startActivity(intent); Programmatically by broadcasting an Intent: String secretCode = "123456789"; ...

There's an easy way to check if the tablet has a faulty touchscreen. Go into Google Play and install a painting app. There are many free painting apps to choose from: just pick a simple one. Run the app and try to paint the whole screen. If the painting doesn't follow your finger, or any parts of the screen can't be painted, you can see the screen is faulty, ...

I could not find a "pure" presentation mode in Aldiko, Acroread 11.7.1, APV, MuPDF, PDFViewer and several others I tried. I finally settled with Perfect Viewer and its Perfect Viewer PDF plugin. Extensive (excessive?!) customisation options, and you can: Disable transitions Drastically simplify what touch actions are allowed (simple tap on left/right ...

Given that you and your friend both have the same tablet, this should be possible. Your friend will need to be rooted as well. Probably the easiest thing would be for him to perform a Nandroid backup which you then transfer to your tablet and restore. If this works, your tablet will be in the same state as his at the time he flashed, so you'll need to ...

You can install the .apk http://www.apkmirror.com/wp-content/themes/APKMirror/download.php?id=2395 Note: Make sure you enable installing from Unknown Sources from Settings>Security. If you cannot install the apk, you will have to root your tablet. You can probably find a guide at forum.xda-developers.com After rooting your device, install Xposed installer ...

You can't track the device after factory resetting it, since it removes the Android Device Manager and/or its settings. It is purely for preventing your information from being accessed.

DSMLawmo is a Samsung system app that is preinstalled, it is not malware but it does have many of the characteristics of malware likely leading to a false positive detection, the description is: "DSM states for "Dedicated Security Management " Which allows this app to get a full control over the phone using voice channel only... Dsmlawmo is to get ...

I am assuming she either set a new pin/password for you by mistake or you already had a pin/password before she locked it that you cannot remember. Either way you need to reset the pic/password. Here are the instructions for Android 4.4 which you are using: "Older versions of Android — Android 4.4 KitKat and older — have an integrated way to bypass your ...

You did it wrong I guess. There's a "safe" uninstall feature within Kingoroot app. This removes completely the app and the binaries from your device. Open the app Click the three dots upper right, find settings menu. Click "Remove Root". Your device will be rebooted and root should be removed.

In case of the DoorDash app I would say the developers are simply too stupid to understand that in the Android eco system there are still tablets without cellular. From my perspective the only functionality of this app which requires a mobile is the function to make phone calls from within the app (Android CALL_PHONE permission). I am not familiar with ...

Try XODO. I found this question because I was looking for exactly this. Since the question was asked, some new apps are available, so I thought I'd share one that definitely works (it has an option to disable animations). It also seems to have nice annotation tools. Good enough to use in a classroom I'm thinking.

You can install facebook once and log in with different user/pwd to have different setting for different account

What happens when you add a new user account is that a new account (or "User Profile") is created. This has nothing at all to do with the user/group management on OS-Level. You will notice that most how-tos (e.g. this one on HowToGeek) speak about accounts, as the term "user" would be rather misleading. I'm not an Android dev, so I cannot give you a deeper ...

A couple of points for those swinging in from Google.. Uninstalling an app in one user account doesn't remove it from the other, unless you use Titanium or similar, in which case it is GONE. If you install an app at the Play Store web site, it installs into the primary user "desktop", even if you are logged into another desktop using the exact same account ...

Yes, you can use a tablet while it is charging. But, if you do something cpu intense (like 3d game) it can become a little hot. No, you don't need to stop charging when fully charged. The tablet will make sure you don't overcharge.

Rebooting into Safe Mode fixed the issue for me somehow. To go boot into Safe Mode: 1) Long Press on the power button for 1 second. 2) in the power off menu that appears, press and hold the Power Off option. 3) A Reboot into Safe Mode dialog will appear, Click Ok to boot into safe mode. After you have booted once into safe mode, check if your ...

Aside from the usual battery-saving tips (like disabling data / Wi-Fi), you could use an app like Screen Filter to reduce the brightness of the device; this reduces power consumption. If available, you might also invert the colors in your reader app. For example, ezPDF Reader has a Night mode feature which makes the background black and the text white (as ...

There's no special procedure that works with unbranded tablets. As the question you've already found describes, if there's no official upgrade from the manufacturer, you need to look for a custom ROM based on a newer Android version. Where can I find stock or custom ROMs for my Android device? gives you some places to look. There's only one feature peculiar ...
