No, I don't take screenshots of mobile games because I don't know how to take screen shots of apps in Google Android, and I don't feel like installing an app for taking screenshots of mobile games.
I have taken screenshots on my tablet, but I don't use my phone too often, other than for calling, so I have never taken a screenshot of a mobile game on my phone.
Speedy Ninja is a jump n' shoot game where all you do is jump. You can dive under the platform to avoid danger, but that's about it, really. This game has a needlessly over-complicated upgrade system that doesn't improve the gameplay in any way, but only serves to distract its players from the fact that this is the simplest game of all time.
It's still fun though.
I don't take screenshots on my phone because I have no idea how to do it. I use the screenshot feature on my tablet because when I review a game, and I need a screen, I just click an on-screen button. That's it.
