I'm glad you're enjoying the game! And that it's not crashing for you :) I'm afraid I didn't do anything, though - compatibility with Android versions and models is entirely up to PyTom (who creates the SDK I use, Ren'py).
I updated my version of Ren'py a few months ago so it could be that if you haven't played for a while. Otherwise it could be that your phone updated its own software and that sorted things out. Either way, I'm glad it works for you! :)
