How to slightly change the application on android?

Question

Android

I'm not good with applications. But I watch YouTube. And I watch it from the application on the phone in a vertical orientation. And in order to put a like, you have to take the phone in your hands, turn it over and only then like it and put it in its place. I want to finish a little so that the like button appears at the end of the video on top of the video itself, for example, like suggested videos.
How to do it? Can you suggest articles or, if not difficult, then describe?))

Answer 1

I don't know about apps

So on its own, no way.
You can try freelancing.

Answer 2

Writing to the application developer is not an option?
