    Lumia 1520 highest cam resolution not working in my app

    I have a camera app and a shiny new 1520. When the highest resolution is selected (3072, 1728) the camera screen is either blank or has a frozen picture. No exception is thrown and the camera is fine if you select another lower resolution.

    The app works fine with a 520, 920 and 1020 (with the added two highest resolutions.

    Has anyone else tried this?

    Update - redefining the preview canvas after changing the resolution fixes the problem (?). It is only needed for the 1520 afaik.

    I dont have a 1520 to test but can you explain it a bit better? Show some code perhaps?

    Try to take a look at Photo Inspector sample here. Its prepared to get High-Res pictures:

    In theory you just need to know whats the full res resolution of 1520 for 4:3 and 19:6 (its different in both resolution and captured megapixels) and use those instead.

    Hi Yan, can you share your code to do this in the meantime? Perhaps it's helpful for him in identifying the issue.
