Is there any way to determine the requirements for an app or game short of spending possibly weeks (for a long game or complex app) testing every single function or finishing the game to 100% completion on various Android versions? I am asking because you can't rely on what the play store says. For example, Foldermount works just fine on my Gamestick running 4.1 despite the "requirements" being 4.3 or later.

That is called luck, If it works in it and you can only check by trying them, unless you don't try it you don't know it simple
