    Lumia 1020 Memory Management

    Hi everybody,

    As we know Lumia 1020 has 2gb memory, but how Mb of memory we allow to use in an app? It's same as high-end devices(1gb memory) or much more. We normally have 300mb and 380mb for extended. Does Gdr2 provides api for to increase memory usage?

    To confirm that, Lumia 1020 owner can look that using this code
    Code:
    DeviceStatus.ApplicationMemoryUsageLimit
    To increase memory usage limit add following to WPAppManifest.xml
    Code:
     
    <App>
    .
    .
    .
    . 
    <!--Add FunctionalCapabilities to bottom-->
     <FunctionalCapabilities>
          <FunctionalCapability Name="ID_FUNCCAP_EXTEND_MEM"/>
        </FunctionalCapabilities>
      </App>

    No, the guidelines have not changed.

    It's possible they will change in the future with GDR3 which will introduce new hardware (screen and CPU) support.

    I believe that the extra memory on the 1020 is mainly used to deal with the bigger camera files that need to be processed and that 1Gb would not be enought. We are talking about ~35-38 megapixels of file to deal with.

    Documentation of WP8 specifically states that the limits are for devices with 1GB of memory or more so the same limits apply here.
