Constraints: FirstVariationOnly

Instructions:

  1. Create a customization answer file using the contents shown in the following code sample.

    <?xml version="1.0" encoding="utf-8" ?>  
    <ImageCustomizations xmlns="http://schemas.microsoft.com/embedded/2004/10/ImageUpdate"  
                         Name="UseOKForUssdDialogs"  
                         Description="Use to change the button label in USSD dialogs from 'Close' to 'OK'."  
                         Owner=""  
                         OwnerType="OEM"> 
    
      <Static>  
    
        <Settings Path="Phone/PhoneSettings">  
          <Setting Name="UseOKForUssdDialogs" Value="" />
        </Settings>  
    
      </Static>
    
    </ImageCustomizations>
    
  2. Specify an Owner.

  3. Change the button label in the USSD dialog by setting UseOKForUssdDialogs to one of the following values:

    ValueDescription

    0 or 'False'

    USSD success and failure dialogs have a single button to close the dialog labeled Close

    1 or 'True'

    USSD success and failure dialogs have a single button to close the dialog labeled OK

Testing steps:

  1. Flash the build containing this customization to a phone that has a UICC.

  2. Open the Phone app and tap the keypad button.

  3. Use several USSD codes and strings to bring up a USSD success dialog and a USSD failure dialog.

  4. Verify that the button label in the dialog shows OK.
