why does not develop the main web browser programs such as Chrome or Firefox for UBports? Is there any technical or License problem?

Hi everyone,
How can I install a chrome (or chromium) web browser on UBports?

Hi every one,
I'm going to test ubports on my own Samsung tablet E 8.0 device but when I want to select my device manually, There is not any Samsung mobile to test!
How can I start my device testing?
Which list model is better to select and start?
