The GfxTablet project should allow you to do this. It's network-based rather than USB though.

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)....

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 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

A touchscreen tablet is not like a Wacom tablet. Drawing tablets use a stylus with one or two pressure-sensitive tips and several buttons. The stylus is also sensitive to the angle you hold it at, and the tablet can detect when the stylus is hovering above the tablet, even with no contact. A drawing tablet has a resolution of a fraction of a millimetre. You ...

Turning the tablet off at night will most likely extend its life, but this defeats the purpose of having a tablet, since a key feature of the tablet is instant power-on from standby. Generally, there are two things that drain the battery of any device: the display (when it's turned on), and any wireless communications (3G, WiFi, etc). If you really want to ...

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 ...

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,...

Short answer: It depends. Long answer: Android developers have the ability to specify requirements for their apps both in terms of software (minimum OS version, for example) and hardware. For example, an app that does turn-by-turn navigation may require the Android device it's being installed on to have built-in GPS. Such an app would be listed as "...

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 ...

It's up to the app. Android provides mechanisms for app authors to specify different UI layouts for the different screen sizes (roughly speaking: phones, 7in tablets, 10in tablets). This means that the app might rearrange its buttons or use larger sizes to fill a 7in screen, or it might do something more radical like switch to a two-pane layout (such as ...

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 ...

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 ...

OLED screen are very bad for burn in and colour leaking (even worse that plasma screens in alot of cases) en.wikipedia.org/wiki/Screen_burn-in and so leaving them on the same screen for some time would not be a good idea You might also find the general life of the device shortened because of the hardware being used all the time, but unless you are putting ...

It most likely will work, depending on a few facts: your device must have GPS built-in you must have the map data downloaded while connected to WiFi (e.g. using Maps (-) Offline Navigation, which fills Google Map's cache) for navigation, you must have calculated the route in advance I'm not sure whether Google Maps supports pre-calculation for navigation --...

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, ...

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"; ...

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 ...

Typically yes, you can use a USB hub to connect multiple devices without any issues. Whether or not these peripherals perform adequately may depend on the amount of power that they require, but that's common to un-powered USB hubs in any situation. Google's Android support pages actually mention USB hubs. E.g. the Nexus S support page on keyboards and other ...

Yes, I had the same issue, it never worked for any PC USB Keyboards, except the one which we bought from DOMO, that nCase K6. That K6 worked perfectly (even to my PC). But a PC USB mouse worked on my DOMO Slate X3G. Buy a nCase K6 or, preferably you could install USB Host Controller from Play Store, as said by the first answer.. That should fix your issues.

If you already have the app on your phone, you might want to take a look at AppMonster. This app allows you to create backups of your apps' .apk files to your SD card (the Pro version even can do so automatically each time you install/update an app, so you always have the chance to revert to a previous version if an update breaks something). You can then ...

As you already put it into your question: You might consider installing a VNC server on your mother's device. Admitted, most of them require root access, so this could be a problem. However, at least one claims to do without root: VMLite VNC Server. But it comes at a cost: There's no free version available, so you'ld have to pay about EUR 6. To give you a ...
