Is it possible to change the background image of the start screen from an app?
Example: I have an generated image within the app and want to set it as background image (for tiles) of my start screen in windows phone 8.1 by a simple tap on a button.
Unfortunately, there is currently no API that allows changing the Windows Phone 8.1 Start Screen background image programmatically.

How to access to Standard Camera Capture UI from code in winphone 8.1?
I tried FileOpenPicker to open Picture Library (added button to access camera on navigation bar). Is there any another way to access Camera Capture UI than using FileOpenPicker, for example- custom UI with class MediaCapture or is it not a good idea to use MediaCapture for simple capturing image? It mean, Can I call to Standard Camera Capture UI if I know what happen when click button camera in FileOpenPicker?
Sadly, there isn't one in Phone 8.1, see here: CameraCaptureTask missing in Window Phone 8.1 runtime???
You can use the FileOpenPicker to let the user choose an existing image or if they so choose, they can capture on in the moment by tapping the camera button in the app bar.
Windows Phone 10 is set to bring this back, as far as I know.

I tried using:
CameraCaptureUI dialog = new CameraCaptureUI();
But its supported in Windows 8.1 and not Windows Phone 8.1
Try Using Video Brush.
Just Put the Video brush inside the Canvas and you can have full control over thhe UI and as well as code behind.

I want to set my lock screen and background image using c# in windows phone 8.1(WinRT) app.I have a button which jobs is to change lock screen by selecting the image from the gallery or made at runtime .Is there any api or specific tutorial or document available ?
Need help?
There is no way to set the lock-screen wallpaper in a Windows Runtime Phone app at this time - you need to keep using Silverlight to use the lock screen API.

EDIT:
Not applicable to 8.1, but there is now an API for setting the Start Screen and Lock Screen backgrounds in Windows 10 - UserProfilePersonalizationSettings. The API is universal, but it only does something meaningful on Desktop and Mobile (the IsSupported property is true). On other platforms like Xbox, it just fails silently (no exception, but no background is set either).
In my wp8 phone app, I want to show overlay window when a particular action is completed based on certain data a(eg: summary, or game level details).

How can I set my app Tile background to Start Menu Color?
I am fairly certain you cannot programmatically access the Start screen color programmatically, though I cannot seem to find a clear reference to that newer than the Release Preview.
You can set the tile background color explicitly via the app manifest
