Fair use images can be displayed in the Explore feed in WP for Android 2.5.195-r-2017-04-21. For example, right now if I tap the app icon on my phone I go to a page (not the mobile view page) that begins with News. There is the Mumbai Indians logo which is a fair use image.
Another user believes the Android app will display images from any news story (and not display the free news image that is carefully chosen by admins which is visible in a laptop).
This seems related to T165807 mismatched news images.
