Question: Are There Really Secret Emojis that Google and Apple are colluding to suppress information about?

Answer: Yes! As of July 2015 there are a number of official emojis they are refusing to show on their devices. Part of the problem is that some of these are new additions for Unicode 8 that was released June 17 2015. But some of these are old emojis that should have been added by now. For example the middle finger was from Unicode 7. This following table is based on what is missing in Chrome on Android Lollipop on July 2015.
