[Android][iOS] Image Asset Named with ISO Code doesn't Work

[Soap-141]

Current behavior

When an image asset is named with an ISO code representing a language the image doesn't work on Android and iOS.

For example: image_bg.png.

The image on the left is named Doge.png and the Image on the right is named Doge_bg.png.

UWP:

Android:

Expected behavior

The image should work properly.

How to reproduce it (as minimally and precisely as possible)

1. Download SampleImg.zip
2. Open the solution in Visual Studio
3. Start the application in UWP
4. Notice two images
5. Start the application on Android or iOS
6. Notice only one image

Workaround

Rename the image asset.

Example: Doge_bg.png would not work but Doge.png would work.
