Why are some models not supported?

I have the LG Velvet LM-G900EM. This model is not supported but other LG Velvet’s are supported. Why is that and can you make my model supported?

Hi, LM-G900EM is the Velvet EU model, we don’t get the model, so the test is not done. But if these phone models are the same in different regions, theoretically the glass can work. Anyway, we will try our best to get this model and do test.

Thanks, let me know if you tested it, if it works or not. I am gonna buy the glasses if it works with my phone.
