I am familiar with your problem. I recently bought a led light for my car, it has an android control function, but I couldn't get it set up. I ended up having to buy a new LED light at https://www.amazon.com/car-lights-car-led-lights/dp/B09L86JRRM, and guess what? The problem was solved. I set up all the functions with no problems. So maybe you should also buy a LED backlight from another manufacturer. Because often, it is just an incompatibility. Try other options. At least it certainly helped me. Good luck to you.
