How can I view ALL videos received via iMessage in full screen mode?

[BlazingGold]

When receiving a video in messages, how do you click on it to make it full screen? Most times it just plays in the tiny box in messages. However, sometimes when I click on it, it blows up like it should to watch full screen. Seems very hit or miss though. Any way to always do it?

It depends on the format of the video. On occasion, all you have to do is double-tap on the video to get it to display full screen.
