Twitter has announced that it is starting a test on Android that will ask some users if they have read an article if they are about to retweet it. If the device can detect the person has not opened the article within the Twitter app, it may display a prompt encouraging you to read before you share.

But this is just a test, and not all eligible people will see the prompt even if they retweet without reading. Also given this is likely to be a push to stop misinformation spreading in the US, it is a test limited to Android in a nation where the majority of smartphones in use are iPhones.
