Screen recording application recommendations?

[Icefrost]

My current smartphone doesn't have an inbuilt screen recording features and it's something that's very important for me in any smartphone that I'm making use of. I have managed to download DU screen recorder but it's working on my smartphone as it shutdowns on its own whenever I launch it.

I have never used any screen recording applications before because I don't have any use for it. I think my smartphone comes with the feature but I don't think that I have ever used it for once.
