Windows phone back button task preview - windows-phone-8

On the windows phone when you press and hold the back button a collection of tiles will appear that represent apps that were recently run or are running in the background. Generally the tiles will show a preview of the app in the visual state it was in when it last navigated away from. I have seen some apps however that will show their logo on this tile regardless of the state the app was in when navigated away from. I have been beating my head against the internet trying to find how this is done. Perhaps I am missing the proper terms to search for in order point myself in the correct direction. Does anyone know how to accomplish swapping the back button history preview image or perhaps help me find the correct search terms to locate help on this?

iOS 9.2 breaks app protocol handling

I have a link in my app that points to an app protocol of type myProtocol://". Until a few days ago this was working completely fine, whenever you clicked on the link, the native app would open.
However, iOS9.2 seems to have broken this. Now what happens is when the links is clicked, I get a prompt to open the native app which disappears after roughly 1 second, not even close to giving the user enough time to access. Shortly afterwards I get prompted to go to the App Store to the app's page.
Any idea why this is happening and what changes in iOS9.2 that is causing this would be helpful.
It seems that with iOS9.2, Apple is making a move towards Universal Links and traditional deeplinking is not supported anymore. While I was not able to find any information published direct on iOS9.2 release notes, following links indicate the same:

How to create links based on changing text on the screen

I am trying to figure out a way to create links to point to help files in my application based off the text on the screen.
Lets say my application reports the status of a car if it is running or not. If it is running everything is ok, but if it is not running it will display a reason such as:
In Park
Door is open.
Shut off.
Flat tire
When it displays the reason on the main page I want it to have a link pointing to the help file which will include a resolution to get the car back up and running.
The problem I am having is the the reasons change on the fly and update in real time. The resolutions for the problems are all different.
To give some background, the application is asp.net web application. I tried searching the web and I tried linking it to a simple page which had the links to the correct pages but that requires more user involvement. I want it to be click the problem and bring it right to the page.
Any information or suggestions would be great.
Thanks

Sliding control in wp8

I have developed wp8 app and looking for a control to slide. I am showing single verse in the page and I want the user to slide (forward and backward) to show next verse, verses may reach 286. I have seen this feature in many application in windows phone store, but I don't what wp8 control they are using.
appreciate your feedback!
Panorama is that you have one image in the background you move a little everytime you go to one side, it is what is used in the image app.
But since you need 286, you should not use the panorama control. Then you should rely on the pivot but beware of microsoft not wanting the users to be confused and caught inside 286 pages, so you need to give the user and overview and use a button that can return a person to the start page.

Windows Phone Live Tiles with Background from the Web and updated automatically.

I am currently working on a windows Phone App that is supposed to have a flipping liveTile. Here's how it is supposed to work:
The Front will be generated from UI Elements that are filled with Data pulled from a Web API. That Backside will be generated from an Image downloaded from the Web. the Idea ist to have one Image for the small liveTile size and one for the big live tile.
Can someone give me a hint, how i can update the livetile automatically without having to have the app opened? I can't do it with a Push notification because i don't have a server to do the pushing in the first place. I tried using the ShellTileSheduler and RemotImageURI property but this doesn't work for different sizes. Am i missing something? Has anyone done somehting like this and has an idea how to do it? I'm getting really frustrated.
Here is a good start to generate tile

Windows Phone Back Key Behaviour When Options Appear

I am developing an app. A page showing full image and when you tap on the image, image caption and sound options appear from two opposite sides i.e caption from left and sound options from right with translate animations.
I want to be clear about that when I press back button, I can navigate to back page or I have to make those options disappear first and then again press back key to go to previous page from microsoft certification point of view?
I believe this is the same since windows phone 7.
You should be allowed to capture the back event and add some code. I don't think that is seen as bad practice, you just aren't allow to stop it.
Saying that, I don't think you can easily do a double back. you might have to check.
Here is a fairly useful post on the subject:
WP7: navigate twice back
which leads to another post about navigating the stack:
