Windows Phone 8.1 camera app prevent pin passcode from showing - windows-phone-8

In WP8.1, one can write a phone camera app which is used when the camera button is tapped (to replace the out-of-the-box Windows Camera App or Lumia Camera App)
Setting the camera app works fine, and launching it with the camera button works too, however, when a pin / passcode is set on the device, it first asks for the passcode / pin before showing the camera app. For the Lumia and Microsoft Camera app, they get launched without asking for the pin.
Do you have any idea why?
Thanks

PWA html5 open device camera as soon as page is launched

i have a pwa where i am showing a standard input tag like below. this let user tap on it and get access to device camera. However, i want to open the camera as sooon as you open the webpage. is it possible?
current code:
<input type="file" accept="image/x-png,image/jpeg,image/gif" capture="camera"/>
Like Mathias said access to the camera is gated behind user permission.
Instead of an input tag like you are using you should really use the Media Capture API.
You have to get the user's permission to access the camera first. Once you have that permission you can connect to the camera and capture photos and video.
Note: Apple has disabled access to camera from homescreen web apps. No idea when they will turn this on. You can access the camera from regular Safari on iOS, just not from a homescreen web app even though it is the same engine.

Is it possible to use Camera in Background or Hidden Mode in Windows Phone 8?

There are many ways we can access Camera in Windows Phone 8 / 8.1. Most of them launch specific UI for that.
Is there any way we can access camera without displaying anything related to camera in Windows Phone 8/8.1 ?
I want my camera to capture an image when my application opens.

No Basic Camera UI for Windows Phone 8.1

OK. Questions.
I know there is no CameraCaptureUI in Windows phone 8.1, so I have to use MediaCapture class. That's fine but what about UI? Do I have to make and position button in my screen from scratch?(like flash button, front camera button etc)
About Nokia Imaging SDK. does it provide any UI? and can I use that API for taking picture instead of working directly with MediaCapture?. I tried to find out some information about initializing and taking picture using nokia imaging sdk, but I couldn't find.
Can you let me know any useful link for implementing MediaCapture in windows phone 8.1? There are lots of links but only for silverlight 8.0 not 8.1.
You can use FileOpenPicker and if you specify .png and .jpg in the list of file types, the picker will have a camera capture button that will open standard camera capture UI:
FileOpenPicker picker = new FileOpenPicker();
picker.FileTypeFilter.Add(".png");
picker.FileTypeFilter.Add(".jpg");
picker.ContinuationData["Data"] = "Something"; // Will be passed back to the app after the picker finishes
picker.PickSingleFileAndContinue();
If you still want to write your own UI, check this link: http://www.romasz.net/how-to-take-a-photo-in-windows-runtime/

Samsung Smart-TV SDK Internet Browser not available

I just recently downloaded and installed the Samsung Smart-TV SDK 4 (without the IDE, just the emulator). I'm doing this because I want to test the Web browser only, nothing else.
However, when I start up the emulator (2012 version), I can't find any apps when I get to smarthub. I've created a Samsung account but I see no default apps that would usually appear on the TV, not even the Internet browser.
Is there something I'm missing?! I just want to test the Internet Browser.
Cheers.
The emulator is provided for testing your own apps, not to run the apps that people who buy TVs/BRPs/etc get with their device.
Only apps you write and place in the apps/ directory will appear.
That said, you can write an app that does nothing except:
location.href = "http://example.com/";
if i write an app with just location.href = "http://example.com/ is working (i have sdk 5.0) but the browser i get on the TV is not the same browser i get on the tv if i just lunch the integrated web browser app.
The big difference i see is that my app has a browser without the top bar with navigation controls and also there is no mouse pointer and i need to connect an external usb mouse to the tv
how should i do to implement this ?

How to detect phone function

I am building an html5 web-app which will hopefully be mainly run from a mobile device. The app has a phone number which when clicked, calls the number displayed.
This works great if the user is using an iPhone or Android etc, but what if the user is using an iPod Touch or iPad with no phone capabilities? On the iPhone simulator in XCode, i get an error message saying that safari cannot open the page.
Is it possible to detect if the device has a phone, and if not, disable the link
Thanks
