I figured out the issue, by using a different app that can play rpg maker mv games, I found out that when running the game with WebGL compatibility is the issue, turning that off fixes the issue.
Oh I see, that is great to hear and also good to know if someone in the future is reporting a similiar problem. And yeah it sounds logical, if it is some kind of emulator it makes sense that it may cause graphical problems. It most likely has problems grabbing and loading the "visibility range image" and just turns it completely black, is my guess.
Rpg maker offer a option to also export the games in a mobile game format if I remember correctly, so it should be able to run natively on smartphones. I personally just never experimented with that feature and have tested it out.
But great to hear it works now : )
