I don't think that will work either. We had a user on discord who tried both JoiPlay and official app. The problem here is mostly related to the phone's SoC not being able to handle new Ren'py version. And switching Ren'py version isn't as easy as you may think.
I'm probably the guy, i had many problems with the 7.4.X Ren'Py and asked for alternative builds of the games in many discords. Tom (Ren'Py creator) changed how Ren'Py render works in 7.5.X/8.0, now it works like a charm. The latest JoiPlay uses Ren'Py 7.5.X/8.0 (and forces the games to use it too). I really think its worth a try.
